PART I

Item 1. BUSINESS.

GENERAL

As used herein, the term “Company” means Koss Corporation and its consolidated subsidiaries, unless the context otherwise requires. The Company was incorporated in Delaware in 1971.

The Company operates in the audio/video industry segment of the home entertainment industry through its design, manufacture and sale of stereo headphones and related accessory products.

The Company does not report its finances by segment, as the Company’s principal business line is the design, manufacture, and sale of stereo headphones and related accessories. The percentage of total revenues related to this central business line over the past three fiscal years was:

	2005			2004			2003
Stereophones		100	%		100	%		100	%

The Company’s products are sold through audio specialty stores, the Internet, direct mail catalogs, regional department store chains, discount department stores, military exchanges, prisons, and national retailers under the “Koss” name and dual label. The Company also sells products to distributors for resale to school systems, and directly to other manufactures for inclusion with their own products. The Company has more than 1,600 domestic dealers and its products are carried in approximately 16,000 domestic retail outlets. International markets are served by domestic sales representatives and a sales office in Switzerland which utilizes independent distributors in several foreign countries.

In May of 2003, the Company purchased the assets of ADDAX Sound, a company that specializes in the development of communications headsets. ADDAX is principally a design and source operation utilizing contract manufacturers in Asia. The assets of ADDAX included inventory, receivables, tooling, furniture and fixtures as well as patents on designs for telecommunications products.

ADDAX has been renamed Bi Audio and services the public safety market through distributors. Bi Audio develops and sells headsets and microphones for communication via two-way radio by police, fire, and security personnel. Bi Audio also sells a line of telephone headsets for the small office and home office as well as for the call center industry. These products are developed on an original equipment manufacturer (OEM) basis and are sold to other companies for distribution at retail or direct to consumers.

Bi Audio also markets headsets to be used with cellular telephones and cordless home telephones. These products are developed on an OEM basis for sale to other companies who redistribute the products through retail channels or direct to consumers.

The Bi Audio category of products represents less than 5% of the Company’s total revenue and is further split into products for three categories Public Safety, Call Center, and Cellular telephone.

Ninety five percent of the Company’s products are stereo headphones for listening to music. The products are not significantly differentiated by channel or application with the exception of products sold to school systems, which sometimes include a microphone. Sales in this application represent less than 5% of the Company’s revenue. There are no other product line differentiations other than the quality of

3

the sound produced by the stereo headphone itself, which is highly subjective. The business could also be classified by distribution channel. Consumers purchase more than 95% of the Koss stereophone range of product through some form of retail channel or reseller.

The Company maintains a sales office in Switzerland. The Company sells its products to independent distributors in countries outside the United States (see Foreign Sales section below), including Western and Eastern Europe, Scandinavia, The Middle East, Africa, Asia, South America, Latin America, the Caribbean, and Mexico. The Company sells products in the Canadian market directly to retailers, and also through a distributor who services smaller specialty accounts. During the last three fiscal years, foreign sales of all Koss products, including the products of Bi Audio (since its acquisition), were as follows:

	2005			2004			2003
Percentage of Revenue
Derived from the Export of Koss Products		28	%		15.7	%		12.5	%

Management believes that it has sources of raw materials that are adequate for its needs.

No employment or compensation agreement exists between the Company and its dealers. The Company has two independent manufacturer’s representatives for distribution. The Company typically signs one year contracts with these manufacturer’s representatives. These agreements are seldom renewed in writing.

The Company has a manufacturer’s representative agreement with a firm in Detroit to work exclusively in the automotive arena. The sales from these agreements accounted for approximately 12% of the Company’s total revenue in 2005. The automotive representative was paid 5% for all business in this area in 2005, and will be paid 4% in 2006, 3% in 2007, and 2% thereafter.

The Company’s remaining agreements with distributors, past or present, pertain to geographic countries without compensation attached. The Company has the right to terminate these agreements with foreign distributors without cause.

INTELLECTUAL PROPERTY

John Koss has been recognized for creating the stereophone industry with the first SP3 stereophone in 1958. The Company regularly applies for registration of its trademarks in many countries around the world in which it does business, and over the years the Company has had numerous trademarks registered and patents issued in countries in North America, South America, Asia, Europe, Africa, and Australia. The Company currently has 193 trademarks registered in 65 countries around the world and patents in 25 countries. The Company has trademarks to protect the brand name Koss and its logo on its products. These trademarks are maintained throughout the countries in which the Company sells its products. The Company also holds many design patents that protect the unique visual appearance of some of its products. These trademarks and patents are important to differentiate the Company from its competitors. Certain of the Company’s trademarks are of material value and importance to the conduct of its business. The Company considers protection of its proprietary developments important; however, the Company’s business is not, in the opinion of management, materially dependent upon any single trademark or patent.

See Part II, Item 7 — “MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS” herein for information relating to the Company’s license agreements.

SEASONALITY

Although retail sales of consumer electronics are typically higher during the holiday season, stereophones have also seen increased interest as gift items over the years. Management of the Company is of the opinion that its business and industry segment are no longer seasonal as evidenced by the fact that 47% of sales occurred in the first six months of the fiscal year ended June 30, 2005, and 53% of sales occurred in the latter six months of that fiscal year. Management believes that the reason for this level performance of sales to retailers is related to the fact that stereo headphones have become replacement items for portable electronic products. Therefore upgrades and replacements appear to have as much interest over the course of the year as gifts of stereophones.

WORKING CAPITAL AND BACKLOG

The Company’s working capital needs do not differ substantially from those of its competitors in the industry and generally reflect the need to carry significant amounts of inventory to meet delivery requirements of its customers. From time to time, although rarely, the Company may extend payment terms to its dealers for a special promotion. For instance, the Company has in the past offered a 90-120 day payment period for certain customers, such as computer retailers and office supply stores. Based on historical trends, management does not expect these practices to have any material effect on net sales or net income. The Company’s current backlog of orders is not deemed material in relation to net sales during fiscal 2005.

CUSTOMERS

The Company markets a line of products used by consumers to listen to music. The Company distributes these products through retail channels in the U.S. and independent distributors throughout the rest of the world. The Company markets its products to approximately 2,000 retailers and distributors worldwide. During 2005, the Company’s sales to its largest single customer, Wal-Mart Stores Inc., were approximately 15% of total gross sales. The Company is dependent upon its ability to retain a base of retailers and distributors to sell the Company’s line of products. Loss of retailers and distributors means loss of product placement. The Company has broad distribution across many channels including specialty stores, mass merchants, electronics stores, and computer retailers. Management believes that any loss of Wal-Mart’s revenues would be partially offset by a corresponding decrease, on a percentage basis, in expenses, thereby partially reducing the impact on the Company’s operating income. The five largest customers of the Company (including Wal-Mart) accounted for approximately 42% of total sales in 2005.

COMPETITION

The Company focuses on the headphone industry. The acquisition of ADDAX in 2003, now Bi Audio, expands the Company’s investment into additional categories of headsets, headphones, and stereophones. In the stereophone market, the Company competes directly with approximately five major competitors, several of which are large and diversified and have greater total assets and resources than the Company. The Company’s single product focus is unique in the marketplace. The extent to which retailers view the Company as an innovative vendor of high quality headphone products, and a provider of excellent after sales customer service, is the extent to which the Company maintains a competitive advantage. The Company relies upon its unique sound, quality workmanship, brand identification, engineering skills, and customer service to maintain its competitive position.

RESEARCH AND DEVELOPMENT

The amount spent on engineering and research activities relating to the development of new products or the improvement of existing products was $173,000 during fiscal 2005 as compared with $125,000 during fiscal 2004 and $134,000 during fiscal 2003. These activities were conducted by both Company personnel and outside consultants.

ENVIRONMENTAL MATTERS

The Company believes that it has materially complied with all currently existing federal, state and local statutes and regulations regarding environmental standards and occupational safety and health matters to which it is subject. During fiscal 2005, 2004 and 2003, the amounts incurred in complying with federal, state and local statutes and regulations pertaining to environmental standards and occupational safety and health laws and regulations did not materially affect the Company’s earnings or financial condition.

EMPLOYEES

As of June 30, 2005, the Company employed 95 people. The Company also utilizes temporary personnel to meet seasonal production demands.

FOREIGN SALES

International markets are serviced through manufacturer’s representatives or independent distributors with product produced in the United States. The countries are too numerous to mention here but include countries in the following regions: Western and Eastern Europe, Scandinavia, The Middle East, Africa, Asia, South America, Latin America, the Caribbean, and Mexico. The Company sells products in the Canadian market directly to retailers, and also through a distributor who services smaller specialty accounts.

In the opinion of management, the Company’s competitive position and risks relating to the conduct of its business in such markets are comparable to the domestic market. In addition, the governments of foreign nations may elect to erect trade barriers on imports. The creation of such barriers would reduce the Company’s revenue and profit. In addition, any fluctuations in currency exchange rates could affect the pricing of the Company’s products and cause customers to purchase lower-priced, less profitable products. For further information, see Part II, Item 7 and Note 11 to the consolidated financial statements accompanying this Form 10-K.

The Company operates a small sales office in Switzerland to service the international export marketplace. The Company is aware of no material risks in maintaining this operation. Loss of this office would result in a transfer of sales and marketing responsibility. The Company uses contract manufacturing facilities in the Peoples Republic of China, Taiwan, and South Korea. These independent supplier entities are distant from the Company, which means that we are at risk of business interruptions due to natural disaster, war, disease, and government intervention through tariffs or trade restrictions. The Company maintains finished goods inventory in its US facility to mitigate this risk. Finished goods inventory is stocked at an average of approximately 90 days demand per item. Recovery of a single facility through a replacement of supplier in the event of a disaster or suspension of supply could take 120 days. The Company believes that it could restore production of its top twelve selling models (which represent 75% of the Company’s sales revenue) within 1 year. The Company is also at risk if the trade restrictions are introduced on its products based upon country of origin. In addition, any increase in tariffs and freight charges would not be acceptable to pass along to the Company’s customers and would directly impact the Company’s profits.

Item 2. PROPERTIES.

The Company leases its main plant and offices in Milwaukee, Wisconsin from its Chairman, John C. Koss. On May 28, 2003, the lease was renewed for a period of five years, and is being accounted for as an operating lease. The lease extension maintained the rent at a fixed rate of $380,000 per year. At anytime during this period the Company has the option to renew the lease for an additional five years for the period commencing July 1, 2008 and ending June 30, 2013 under the same terms and conditions. The lease is on terms no less favorable to the Company than those that could be obtained from an independent party. The Company is responsible for all property maintenance, insurance, taxes, and other normal expenses related to ownership.

All facilities are in good repair and, in the opinion of management, are suitable for the Company’s business purposes.

The Company’s stockholders are entitled to receive dividends as may be declared by the Board of Directors and paid out of funds legally available therefore. The Company began paying dividends for the quarter ended September 30, 2002 and has paid a dividend for each quarter since, including the last fiscal quarter ending June 30, 2005. On June 15, 2005, the Company announced its quarterly dividend of $0.13 per share for stockholders of record on June 30, 2005. Although the Company anticipates it will continue to pay a quarterly dividend, the decision to pay dividends and the amount of such dividends are within the sole discretion of the Board of Directors, who meet quarterly. The decision to pay dividends will depend on the Company’s operating results, financial condition, tax considerations, alternative uses for such funds, and other factors the Board of Directors deem relevant, and there can be no assurance that dividends will be paid in the future.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

LIQUIDITY AND CAPITAL RESOURCES

During fiscal 2005, cash provided by operations was $7,963,037. Working capital was $17,532,194 at June 30, 2005. The net increase in working capital of $724,960 from June 30, 2004 represents primarily the net effect of an increase in cash, accounts payables, income taxes and accrued liabilities. The increase in the Company’s accounts receivable is attributable to higher sales experienced in the last quarter.

Capital expenditures for new property and equipment (including production tooling) were $1,170,494, $1,344,169, and $627,567, in fiscal 2005, 2004, and 2003, respectively. Depreciation charges totaled $816,857, $590,414, and $569,776, for the same fiscal years. Budgeted capital expenditures for fiscal 2006 are $1,723,700. The Company expects to generate sufficient funds through operations to fund these expenditures.

Stockholders’ investment increased to $22,121,242 at June 30, 2005 from $21,089,787 at June 30, 2004. The increase reflects net income of $4,493,827. On June 15, 2005, the Company declared a quarterly cash dividend of $0.13 per share, $486,918 payable on July 15, 2005 to stockholders of record on June 30, 2005, which is recorded as dividends payable.

The Company’s credit facility matures on November 1, 2005. This unsecured credit facility provides for borrowings up to a maximum of $10,000,000. The Company can use this credit facility for working capital purposes or for the purchase of its own common stock pursuant to the Company’s stock repurchase program. Borrowings under this credit facility bear interest at the bank’s prime rate, or LIBOR plus 1.75%. This credit facility includes certain financial covenants that require the Company to maintain a minimum tangible net worth and specified current, interest coverage, and leverage ratios. The maximum leverage of the Company, which consists of the ratio of its total liabilities to its tangible net worth, must not exceed 1.50 to 1.0. The tangible net worth of the Company must not fall below $12.5 million at any time. The fixed charge ratio of the Company, which consists of the ratio of its earnings before interest, income taxes, depreciation, amortization, and other non-cash charges to its total interest expense, must not be less than 2.10 to 1.0. The current ratio of the Company, which is the ratio of its current assets to its current liabilities, must exceed 2.50 to 1.0. The Company has been and is well within these requirements. However, if the Company at some point in the future fails to meet the financial covenants, the lender may accelerate the debt and allow creditors to foreclose on the assets. The Company uses its credit facility from time to time, although there was no utilization of this credit facility at June 30, 2005 or June 30, 2004.

In April of 1995, the Board of Directors approved a stock repurchase program authorizing the Company to purchase from time to time up to $2,000,000 of its common stock for its own account. Subsequently, the Board of Directors periodically has approved increases in the stock repurchase program. The most recently approved increase was for additional purchases of $2,000,000, which occurred in October of 2004, for an aggregate maximum of $40,500,000. The Company intends to effect all stock purchases either on the open market or through privately negotiated transactions, and intends to finance all stock purchases through its own cash flow or by borrowing for such purchases. The Company will continue to repurchase its shares from the market when the board determines the shares to be undervalued. The Company may elect to use the purchase of these shares to minimize the dilutive effects to its stockholders when the Company’s stock is used in acquisitions as consideration. The Company has no immediate plans to make another acquisition at this time.

10

For fiscal 2005, the Company purchased 99,250 shares of its common stock at an average net price of $22.33 per share, for a total purchase price of $2,216,875. As of the date hereof, the Company’s Board of Directors has authorized the repurchase by the Company of up to $3,978,200 in Company common stock at the discretion of the Chief Executive Officer of the Company.

From the commencement of the Company’s stock repurchase program through June 30, 2005, the Company has purchased a total of 5,074,084 shares for a total gross purchase price of $42,998,735 (representing an average gross purchase price of $8.48 per share) and a total net purchase price of $36,521,800 (representing an average net purchase price of $7.20 per share). The difference between the total gross purchase price and the total net purchase price is the result of the Company purchasing from certain employees shares of the Company’s stock acquired by such employees pursuant to the Company’s stock option program. In determining the dollar amount available for additional purchases under the stock repurchase program, the Company uses the total net purchase price paid by the Company for all stock purchases, as authorized by the Board of Directors.

2005 RESULTS OF OPERATIONS COMPARED WITH 2004

Net sales for 2005 were $40,286,691 compared with $40,493,211 in 2004, a decrease of $206,520 or less than 1%. This was due to the Company experiencing a decline in segments of its domestic retail sales , which was partially offset by growth in segments of Europe where shipments were up 82% for the fiscal year.

Gross profit, as a percentage of net sales, was $15,069,931 or 37% in 2005 compared with $15,961,953 or 40% in 2004. The decrease is primarily due to the Company experiencing higher freight costs on incoming shipments of supplies.

Selling, general, and administrative expenses for 2005 were $8,544,383 compared with $8,089,765 in 2004, an increase of $454,618 or 6%. The increase was a result of the Company experiencing higher marketing expenses associated with participation in the Consumer Electronics Show held in January 2005.

Income from operations was $7,395,828 in 2005 compared with $8,965,177 in 2004, a decrease of 21%. Interest income was $64,795 in 2005 compared with $22,311 in 2004, an increase of 191%. Interest income fluctuates in relation to cash balances on hand throughout the year and fluctuations in interest rates earned.

Royalty income was $805,485 in 2005 compared with $1,071,638 in 2004, a decrease of 25%. The decrease in royalty income was primarily a result of the Company terminating a License Agreement with Jiangsu Electronics Industries Limited (Jiangsu). Effective November 23, 2004 the Company terminated the License Agreement dated November 15, 1991, as subsequently amended between the Company and Jiangsu. As a result of the termination, other than Jiangsu’s post-termination right to sell Company-approved licensed products, as set forth in the License Agreement, Jiangsu no longer has the right to use certain Company trademarks in connection with the manufacture, marketing and distribution of Jiangsu’s products under this license agreement. Royalty income on all previously approved products, which are already in the pipeline, will still be owed to the Company.

Effective June 30, 2003, the Company entered into a License Agreement (the “License Agreement”) with Sonigem Products, Inc. (“Sonigem”) of Ontario, Canada whereby the Company licensed to Sonigem the right to sell video and communications products under the Koss brand name. This License Agreement covers Canada, requiring royalty payments by Sonigem through June 30, 2010, subject to certain minimum annual royalty amounts. To further enhance the relationship between the Company and

11

Sonigem, on June 30, 2005, the Company announced the extension of its licensing agreement for electronics products with Sonigem. The Amendment to the License Agreement with Sonigem was effective August 1, 2005 (the “Amendment”). The Amendment provides Sonigem with the exclusive right and license to use certain Company trademarks in Canada in connection with the manufacture, production, distribution and sale of an increased number of licensed products, with the prior approval of the Company. In consideration for these increased rights, the Amendment also provides for increased minimum royalty payments payable to the Company, which may partially offset the previously discussed reductions in royalty income.

Effective July 1, 1998, the Company entered into a License Agreement and an Addendum thereto with Logitech Electronics Inc. (“Logitech”) of Ontario, Canada whereby the Company licensed to Logitech the right to sell multimedia/computer speakers under the Koss brand name. This License Agreement covers North America and certain countries in South America and Europe, requiring royalty payments by Logitech through June 30, 2008, subject to certain minimum annual royalty amounts.

The provision for income taxes was $2,902,001 and $3,517,030 in 2005 and 2004, respectively. The effective tax rate was 39% in 2005 and 39% in 2004.

2004 RESULTS OF OPERATIONS COMPARED WITH 2003

Net sales for 2004 were $40,493,211 compared with $33,802,634 in 2003, an increase of $6,690,577 or 20%. This was due to the Company experiencing growth in segments of its domestic retail sales and Europe where shipments were up 72% for the fiscal year.

Gross profit, as a percentage of net sales, was $15,961,953 or 39% in 2004 compared with $13,848,039 or 41% in 2003. The slight decrease is due to shifts in the Company’s model mix.

Selling, general, and administrative expenses for 2004 were $8,089,765 compared with $7,737,030 in 2003, an increase of $352,735 or 5%. The increase was a result of the Company experiencing higher selling expenses associated with higher sales for the fiscal year.

Income from operations was $7,872,188 in 2004 compared with $6,111,009 in 2003, an increase of 28%. Interest income was $22,311 in 2004 compared with $12,711 in 2003, an increase of 76%. Interest income fluctuates in relation to cash balances on hand throughout the year and fluctuations in interest rates earned. Interest expense for 2004 was $960 compared with $14,572 in 2003. The decrease in interest expense is due to the Company’s lack of borrowing activity under its unsecured line of credit during the fiscal year.

On May 1, 2003, the Company acquired certain assets of ADDAX Sound Company (“ADDAX”) in exchange for 19,875 shares of common stock of the Company (value on May 1, 2003 of $317,603 based upon a market price of $15.98) plus $100 in cash and assumed certain liabilities of ADDAX.

Royalty income was $1,071,638 in 2004 compared with $755,364 in 2003, an increase of 42%. The increase in royalty income was primarily a result of increases in sales by licensees under certain royalty agreements with Jiangsu, Sonigem, and Logitech.

The provision for income taxes was $3,517,030 and $2,695,101 in 2004 and 2003, respectively. The effective tax rate was 39% in 2004 and 39% in 2003

DISCLOSURE ABOUT CERTAIN TRADING ACTIVITIES THAT INCLUDE NON-EXCHANGE TRADED CONTRACTS ACCOUNTED FOR AT FAIR VALUE

The Company does not have any trading activities that include non-exchange traded contracts accounted for at fair value.

DISCLOSURE ABOUT EFFECTS OF TRANSACTIONS WITH RELATED AND CERTAIN OTHER PARTIES

The Company has an agreement with its Chairman, John C. Koss, in the event of his death, at the request of the executor of his estate, to repurchase his Company common stock from his estate. The repurchase price is 95% of the fair market value of the common stock on the date that notice to repurchase is provided to the Company. The total number of shares to be repurchased will be sufficient to provide proceeds which are the lesser of $2,500,000 or the amount of estate taxes and administrative expenses incurred by the Chairman’s estate. The Company may elect to pay the purchase price in cash or may elect to pay cash equal to 25% of the total amount due and to execute a promissory note for the balance, payable over four years, at the prime rate of interest. The Company maintains a $1,150,000 life insurance policy to fund a substantial portion of this obligation.

In 1991, the Board of Directors agreed to continue the Chairman’s current base salary in the event he becomes disabled prior to age 70. After age 70, he shall receive his current base salary for the remainder of his life, whether he becomes disabled or not. The Chairman has turned 70. The Company has a deferred compensation liability of $400,000 recorded as of June 30, 2005, and $520,000 as of June 30, 2004 for this arrangement.

The Company leases its main plant and offices in Milwaukee, Wisconsin from its Chairman. On May 28, 2003, the lease was renewed for a period of five years, and is being accounted for as an operating lease. The lease extension maintained the rent at a fixed rate of $380,000 per year. At anytime during this period the Company has the option to renew the lease for an additional five years for the period commencing July 1, 2008 and ending June 30, 2013 under the same terms and conditions. In the opinion of the independent directors of the Board, the lease is on terms no less favorable to the Company than those that could be obtained from an independent party. The Company is responsible for all property maintenance, insurance, taxes, and other normal expenses related to ownership of the property.

All facilities are in good repair and, in the opinion of management, are suitable for the Company’s purposes.

13

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES

The Company’s more critical accounting policies include revenue recognition, royalty income, and the use of estimates (which inherently involve judgment and uncertainties) in valuing inventory and accounts receivable.

     Revenue Recognition

The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred (either FOB shipping point or delivery taken at the Company’s dock); the seller’s price to the buyer is fixed and determinable (pricing is finalized through the purchase order); and collectibility is reasonably assured. These criteria are generally satisfied and the Company recognizes revenue upon shipment. The Company also offers certain of its customers the right to return products that do not meet the standards agreed with the customer. The Company continuously monitors such product returns and while such returns have historically been minimal, the Company cannot guarantee that they will continue to experience the same return rates that they have experienced in the past. Any significant increase in product quality failure rates and the resulting credit returns could have a material adverse impact on the Company’s operating results for the period or periods in which such returns materialize.

The Company provides for certain sales incentives, which include sales rebates. The Company records a provision for estimated incentives based upon the incentives offered to customers on product related sales in the same period as the related revenues are recorded. The Company also records a provision for estimated sales returns and allowances on product related sales in the same period as the related revenues are recorded. These estimates are based on historical sales returns, analysis of credit memo data and other known factors. If the historical data the Company uses to calculate these estimates does not properly reflect future returns, adjustments may be required in future periods.

Products sold are covered by a lifetime warranty. The Company accrues a warranty reserve for estimated costs to provide warranty services. The Company’s estimate of costs to service its warranty obligations is based on historical experience and expectation of future conditions. To the extent the Company experiences increased warranty claim activity or increased costs associated with servicing those claims, its warranty accrual will increase accordingly and result in decreased gross profit.

     Royalty Income

The Company’s net income is significantly affected by the levels of royalty income generated in any given period. Royalty income is recognized when earned under the terms of the Company’s license agreements. These agreements require minimum annual royalty payments. The Company currently has two royalty agreements, which expire in 2008 and 2010, respectively. The inability of the Company to negotiate favorable royalty arrangements and renew current agreements could have a material adverse impact on the Company’s results for the period. Based upon the favorable relationships the Company has with the parties under these license agreements, termination, non-renewal or a renegotiation toward more unfavorable terms under the current agreements is not considered likely.

     Accounts Receivable

The Company performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current credit worthiness, as determined by the review of the customer’s current credit information. The Company continuously monitors collections and payments from customers and maintains a provision for estimated credit losses based upon the Company’s

14

historical experience and any specific customer collection issues that have been identified. The Company values accounts receivable net of an allowance for uncollectible accounts. The allowance is calculated based upon the Company’s evaluation of specific customer accounts where the Company has information that the customer may have an inability to meet its financial obligations (bankruptcy, etc.). In these cases, the Company uses its judgment, based on the best available facts and circumstances, and records a specific reserve for that customer against amounts due to reduce the receivable to the amount that is expected to be collected. These specific reserves are re-evaluated and adjusted as additional information is received that impacts the amount reserved. However, the ultimate collectibility of a receivable is dependent upon the financial condition of an individual customer, which could change rapidly and without advance warning.

     Inventories

The Company values its inventories at the lower of cost or market. Cost is determined using the last-in, first-out method. Valuing inventories at the lower of cost or market requires the use of estimates and judgment. Our customers may cancel their orders or change purchase volumes. Any of these, or certain additional actions, could create excess inventory levels, which would impact the valuation of our inventories. The Company continues to use the same techniques to value inventory as have been used in the past. Any actions taken by our customers that could impact the value of our inventory are considered when determining the lower of cost or market valuations. The Company regularly reviews inventory quantities on hand and records a provision for excess and obsolete inventory based primarily on our estimated forecast of product demand and production requirements for the next twelve months. If the Company is not able to achieve its expectations of the net realizable value of the inventory at its current value, the Company would have to adjust its reserves accordingly.

RECENTLY ISSUED FINANCIAL ACCOUNTING PRONOUNCEMENTS

During May 2003, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity,” which establishes standards for the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. The Company adopted SFAS No. 150 effective July 1, 2003. Upon adoption, the Company recorded a derivative liability for the fair value of a written put option of $125,000 on the balance sheet and a cumulative effect of change in accounting principle of $75,875 (net of the tax effect equal to $49,125) on the income statement. In addition, a contingently redeemable equity interest of $1,490,000, as of July 1, 2003, was reclassified into equity.

During December 2004, the FASB issued SFAS No. 123R, “Share-Based Payments”, which changed the accounting for equity compensation programs. Under SFAS No. 123R, companies that award share-based payments to employees, including stock options, must begin to recognize the expense of these awards in the financial statements at the time the employee receives the award. As allowed by SFAS 123 and SFAS 148, the Company elected to follow APB Opinion No. 25 in accounting for its stock option plan until the effective date of SFAS 123R. The accounting as provided by SFAS 123R will be effective for the Company beginning July 1, 2005, which is the beginning of the Company’s next fiscal year.

Under APB 25’s intrinsic value method, no compensation cost for employee stock options is recognized. Accordingly, the adoption of SFAS 123R’s fair value method will have an impact on the Company’s results of operations, although it will not have an impact on the overall financial position. The impact of the adoption of SFAS 123R will depend on levels of share-based payments granted in the future and is expected to reduce pre-tax earning by approximately $330,000 in fiscal 2006. SFAS 123R also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing

15

cash flow, rather than as an operating cash flow as required under the current standards. This requirement will reduce the net cash provided by operating activities and increase the net cash from financing activities in periods after adoption. While the Company cannot estimate what these amounts will be in the future because it will depend on, among other things, when employees exercise stock options, the amount of cash flows from operating activities in prior periods for such excess tax deductions were approximately $105,000, $330,000 and zero in fiscal years 2005, 2004 and 2003, respectively.

RISK FACTORS

Investing in our common stock involves a high degree of risk. Any of the following risks could have a material adverse effect on our financial condition, liquidity, and results of operations or prospects, financial or otherwise. Reference to these factors in the context of a forward-looking statement or statements will be deemed to be a statement that any one or more of the following factors may cause actual results to differ materially from those in such forward-looking statement or statements.

REDUCTION IN PRESENT LEVELS OF CASH FLOW COULD ADVERSELY AFFECT THE COMPANY’S BUSINESS

The Company’s primary source of liquidity over the past twelve months has been operating cash flows. The Company’s future cash flows from operations (on both a short term and long term basis) are dependent upon, but not limited to:

• the Company’s ability to attract new customers that will sell the Company’s products and pay for them,

• the Company’s ability to retain the Company’s existing customers at the level of sales previously produced,

• the volume of sales for these customers,

• the loss of business of one or more primary customers,

• changes in types of products that the customers purchase in their sales mix,

• the volume of royalty income paid to the Company by its licensees based upon the terms of each royalty agreement, including the inability to negotiate favorable royalty arrangements and renew current arrangements with certain existing favorable terms,

• poor or deteriorating economic conditions which would directly impact the ability of the Company’s customers to remain in business and pay for their products on a timely basis,

• management’s ability to hold the line on any requests for increases in material or labor cost increases, and

• the ability to collect in full and in a timely manner, amounts due to the Company.

In addition, as noted above, the Company’s cash flow is also dependent, to some extent, upon the ability to maintain operating margins. If there were a general downturn in economic conditions or

16

other events that caused the Company’s customers to turn to lower-priced, lower-margin products, the Company’s cash flow and profitability could be materially and adversely affected.

FAILURE TO ATTRACT AND RETAIN CUSTOMERS TO SELL THE COMPANY’S PRODUCTS COULD ADVERSELY AFFECT SALES VOLUME AND FUTURE PROFITABILITY

The Company markets a line of products used by consumers to listen to music. The Company distributes these products through retail channels in the U.S. and independent distributors throughout the rest of the world. The Company is dependent upon the Company’s ability to retain an existing base of customers to sell the Company’s line of products. Loss of customers means loss of product placement. The Company has broad distribution across many channels including specialty stores, mass merchants, electronics stores and computer retailers. Since distribution is broadly based, any loss of a customer directly translates into a reduction in sales volume which can only be replaced by replacing a similar number of representative retail outlets. The inability of the Company’s sales and marketing staff to obtain new distribution outlets translates into a lack of future growth and possibly a setback in sales volumes when loss of current customers occurs. For example, the loss of a customer representing 10% of the Company’s business would translate into a reduction in revenues of up to 10% based upon the point through the fiscal year that the customer was lost. Attracting a new customer during the course of a fiscal year could have a positive impact or simply replace an account which has been lost. In addition, a customer can decide to make a change in the models that it decides to offer for sale. Such changes can take place arbitrarily throughout the course of a year which can cause reductions in sales revenues in proportion to the number of retail outlets that the store represents in the market. The Company may not be able to maintain customers or model selections and therefore experience a reduction in its sales revenue until a model is restored to the mix or a customer is replaced by a new customer. A reduction in sales volume would cause a reduction in profitability. The Company’s failure to retain existing customers, obtain new customers or develop new product lines that customers would choose to offer to consumers could significantly affect the Company’s future profitability. The loss of business of one or more principal customers or a change in the sales volume from a particular customer could have a material adverse effect on the Company’s sales volume and profitability.

SHIFT IN CUSTOMER SPECIFICATIONS TO LOWER PRICED ITEMS CAN REDUCE PROFIT MARGINS NEGATIVELY IMPACTING PROFITABILITY

The Company sells a line of products with a suggested retail price ranging from less than $10 to $1,000. The gross margin for each of these models is unique in terms of percentages. The price range of the products also produces a different level of actual dollar contribution per unit. For example a product with a gross margin contribution of 50% might yield a $5.00 contribution for one item, while another item may feature a 30% gross margin which could yield $50.00. The Company finds the low priced portion of the market most competitive and therefore most subject to pressure on gross margin percentages, which tends to lower profit contributions. Retail preference for lower priced items can reduce profit margins and contributions. The risk is that a shift in retail customer specifications toward lower priced items can lead to lower gross margins and lower profit contributions per unit of sale. Due to the range of products that the Company sells, the product sales mix can produce a variation in terms of a range of profit margins. Some customers sell a limited range of products that yield lower profit margins than others. Most notably, the budget priced headphone segment of the market below $10.00 retail which is distributed through computer stores, office supply stores, and mass market retailers tend to yield the lowest gross margins. An increase in business with these types of accounts, if coupled with a simultaneous reduction in sales to customers with higher gross margins would reduce profit margins and profitability.

17

POOR ECONOMIC CONDITIONS CAN RESTRICT OR LIMIT PRODUCT PLACEMENT, SALES AND REPLENISHMENT WHICH COULD DECREASE PROFITS

Deteriorating or weak economic conditions, or a forecast for the same, can trigger changes in inventory stocking at retail. This may in turn lead to a reduction in model offerings and to out of stock situations. If a retail customer of the Company does not have adequate stocks of the Company’s products to offer for sale in a retail store, consumers may choose another competitive model instead. Customers operating retail stores anticipate future sales demands and inventory products accordingly. Whenever a general economic slowdown occurs, at both the domestic or foreign level, sales volume levels and re-orders change. These changes directly impact the Company’s sales and profitability. The Company is not in a position to determine how it will be affected by these circumstances, how extensive the effects may be, or for how long the Company may be impacted by these circumstances. The Company’s customers respond to changes in economic conditions and any adverse changes in economic conditions can therefore restrict product placement, availability, sales, replenishment and ultimately profitability. These conditions exist domestically and internationally.

MANAGEMENT IS SUBJECT TO DECISIONS MADE OUTSIDE ITS CONTROL WHICH COULD DIRECTLY AFFECT FUTURE PROFITABILITY

Retail customers determine which products they will stock for resale. The Company competes with other manufacturers to secure shelf space in retail stores for the Company’s products. During the course of a year, changes in the customers’ management personnel can ultimately lead to changes in the stock assortment offered to consumers. These changes are often arbitrary. In addition to changes in personnel within the Company’s customers, it is also possible that a strategic decision can be made by a retail customer to consolidate vendors, or to discontinue certain product categories altogether. In these instances, the Company’s management team may not able to convince customers to reverse such decisions. The Company’s management team is also engaged in the effective procurement, assembly, and manufacture of products. The ability to negotiate with suppliers, maintain productivity, and hold the line on cost increases can be subjected to pressures outside the control of management. For example, increases in fuel costs can increase rates of freight. Increases of this nature can seldom be avoided and the Company may not be able to pass such increases along to its customers. Management’s effective control of the manufacturing processes will have a direct impact on the Company’s future profitability. The Company regularly makes decisions that affect production schedules, shipping schedules, employee levels, and inventory levels. The Company’s ability to make effective decisions in managing these areas has a direct effect on future profitability.

ACCOUNTS RECEIVABLE AMOUNTS DUE FROM OUR CUSTOMERS CAN BE LOST AS A RESULT OF CUSTOMER BANKRUPTCY, OPERATIONAL DIFFICULTY, OR FAILURE TO PAY NEGATIVELY IMPACTING FUTURE PROFITABILITY

The Company has significant accounts receivable or other amounts due from the Company’s customers or other parties. The accounts receivable balance at the end of the last 4 quarters averaged approximately $8 million. Terms of payment for customers generally range from cash in advance to net 90 day credit terms. These credit arrangements are negotiated at unspecified and irregular intervals. The largest customers generate the largest receivable balances. If a customer develops operational difficulty it is not uncommon to temporarily suspend payment to vendors. The Company is subject to this risk in the retail marketplace. From time to time a customer may develop severe operating losses which can lead to a bankruptcy. In these cases, the Company may lose most of the outstanding balance due. Occasionally, the Company has been current with a customer at the time such an event occurs. The more material risk is that losing the revenue of the customer which might be more onerous than losing the current outstanding accounts receivable. In addition, many companies that will insure accounts receivables will

18

not do so for the Company’s largest mass market customers. An example of such a loss was KMART Corporation. The Company recorded a loss of approximately $500,000 of which $37,000 has been repaid in 2005 and $312,000 in 2004, when KMART filed for re-organization. KMART was current with the Company at the time that KMART filed Chapter 11 bankruptcy. The Company continued to supply KMART during its post petition re-organization and continues to supply the customer profitably today. The risk is that the Company derives most of the Company’s sales revenue and profits from selling products to retailers for resale to consumers. The failure of the Company’s customers to pay in full amounts due to the Company could negatively affect future profitability.

COMPANY PROFITS CAN SUFFER FROM INTERRUPTIONS IN SUPPLY CHAIN

The Company operates a small sales office in Switzerland to service the international export marketplace. The Company is aware of no material risks in maintaining this operation. Loss of this office would result in a transfer of sales and marketing responsibility. The Company uses contract manufacturing facilities in Mainland China, Taiwan, and South Korea. These independent supplier entities are distant from the Company which means that the Company is at risk of business interruptions due to natural disaster, war, disease, and government intervention through tariffs or trade restrictions that do not affect the domestic market. The Company maintains a finished goods inventory level in the Company’s US facility to mitigate this risk. The approximate level of finished goods inventory is stocked at an average of 90 days demand per item. Recovery of a single facility through a replacement of supplier in the event of disaster or suspension of supply could take approximately 120 days. The Company believes that it could restore production of its top fourteen selling models (which represent 75% of the Company’s sales revenue) within 1 year. The Company is also at risk if trade restrictions are imposed on the Company’s products based upon country of origin. In addition, any increase in tariffs and freight charges may not be acceptable to pass along to the Company’s customers and could directly impact the Company’s profits.

FLUCTUATIONS IN CURRENCY EXCHANGE RATES COULD AFFECT PRICING OF PRODUCTS AND CAUSE CUSTOMERS TO PURCHASE LOWER-PRICED, LESS PROFITABLE PRODUCTS

The Company receives a material portion of its revenue and profits from business in Canada and the European Union. To the extent that value of the U.S. dollar increases relative to currencies in those jurisdictions, it increases the cost of the Company’s products in those jurisdictions, which could create negative pressure on the demand for the Company’s products. To the extent that increased prices arising from currency fluctuations decreases the Company’s sales or moves customers to purchase lower-priced, lower profit products, the Company’s revenues, profits, and cash flows could be adversely affected.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

In management’s opinion, the Company does not engage in any material market risk sensitive activities and does not have any market risk sensitive instruments, other than the Company’s commercial credit facility used for working capital purposes and stock repurchases.

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

MANAGEMENT’S REPORT

The consolidated financial statements and related financial information included in this report are the responsibility of management as to preparation, presentation and reliability. Management believes that the financial statements have been prepared in conformity with accounting principles generally accepted

19

in the United States of America appropriate under the circumstances and necessarily include amounts that are based on best estimates and judgments.

The Company maintains a system of internal accounting controls to provide reasonable assurance that assets are safeguarded and that the books and records reflect the authorized transactions of the Company.

Oversight of management’s financial reporting and internal accounting control responsibilities is exercised by the Board of Directors, through an Audit Committee that is comprised solely of independent directors. The Audit Committee is also responsible for the selection and appointment of the independent auditors and reviews the scope of their audit and their findings. The independent auditors have direct access to the Audit Committee, without the presence of management representatives, to discuss the scope and the results of their audit work.

The independent auditors provide an objective assessment of the degree to which management meets its responsibility for fairness of financial reporting. They evaluate the system of internal accounting controls in connection with their audit and perform such tests and procedures, as they deem necessary to reach and express an opinion on the fairness of the financial statements.

Consolidated financial statements of the Company at June 30, 2005 and 2004 and for each of the quarters in the period ended June 30, 2005 and the notes thereto, and the reports of independent auditors thereon are set forth on pages 24 to 39.

Item 9. CHANGES IN AND DISAGREEMENTS WITH AUDITORS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

     On March 15, 2004, the Company dismissed PricewaterhouseCoopers LLP (“PWC”) as its independent public accountants and appointed Grant Thornton LLP as its new independent public accountants. The decision to dismiss PWC and to retain Grant Thornton LLP was made by the Company’s Audit Committee. The decision to dismiss PWC did not involve a dispute with the Company over accounting policies or practices.

     During the fiscal years ended June 30, 2002 and 2003 and the interim period through March 15, 2004, there were no disagreements with PWC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved to PWC’s satisfaction, would have caused PWC to make reference to the subject matter of the disagreement in connection with its reports on the financial statements for such years, and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

Item 9A. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures. The Company maintains a system of disclosure controls and procedures that are designed to provide reasonable assurance that information, which is required to be timely disclosed, is accumulated and communicated to management in a timely fashion. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The Company, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer/Chief Financial Officer, after evaluating the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15(d)-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act)) as of the end of the period covered by this report, have concluded that the Company’s disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure and are effective to provide reasonable assurance that such information is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms.

(b) Changes in Internal Controls. The Company’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) is designed to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. There were no changes in the Company’s internal control over financial reporting that occurred during the Company’s most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. However, because of the inherent limitations in all control systems, no evaluation of controls can provide

21

absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
KOSS CORPORATION

We have audited the accompanying consolidated balance sheets of KOSS CORPORATION and subsidiaries as of June 30, 2005 and 2004, and the related consolidated statements of income, stockholders’ investment, and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. The consolidated financial statements of Koss Corporation and subsidiaries as of June 30, 2003 and for the year then ended, were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements in their report dual dated July 11, 2003 and February 13, 2004.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of KOSS CORPORATION and subsidiaries as of June 30, 2005 and 2004, and the results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

KOSS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ACCOUNTING POLICIES

CONCENTRATION OF CREDIT RISK—The Company operates in the audio/video industry segment of the home entertainment industry through its design, manufacture, and sale of stereo headphones and related accessory products. The Company’s products are sold through audio specialty stores, the Internet, direct mail catalogs, regional department store chains, military exchanges, and national retailers under the “Koss” name and dual label. The Company has more than 1,600 domestic dealers and its products are carried in approximately 16,000 domestic retail outlets. International markets are served by domestic sales representatives and a sales office in Switzerland, which utilizes independent distributors in several foreign countries. The Company grants credit to its domestic and Canadian customers. Collection is dependent on the retailing industry economy. International customers outside of Canada are sold on a cash against documents or letter of credit basis. Approximately 21% and 12% of the Company’s accounts receivable at June 30, 2005 and 2004, respectively, were foreign receivables.

BASIS OF CONSOLIDATION—The consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. All significant intercompany accounts and transactions have been eliminated.

REVENUE RECOGNITION—Revenue is recognized by the Company when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred (either FOB shipping point or delivery taken at the Company’s dock); the seller’s price to the buyer is fixed and determinable (pricing is finalized through the purchase order); and collectibility is reasonably assured. These criteria are generally satisfied upon shipment of the Company’s products. The Company may offer slotting fees, cooperative advertising programs and sales discounts from time to time and the estimated costs for these items are accrued for at the time revenue is recognized. These amounts are recorded as a reduction to sales.

ROYALTY INCOME—The Company recognizes royalty income when earned under the terms of two license agreements, which expire in 2008 and 2010. This agreement requires minimum annual royalty payments. Royalty income owed to the Company is calculated by the licensee and then verified by the Company. Royalty payments are calculated based upon predetermined percentages of net sales of the licensed products or based upon minimum annual royalty payments, as set forth in the Company’s license agreements. Royalty income is booked monthly, on an accrual basis. When the royalty payments are received each quarter, the Company then reduces the accounts receivable accordingly.

INVENTORIES—Substantially all of the Company’s inventories are valued at the lower of last-in, first-out (LIFO) cost or market. If the first-in, first-out (FIFO) method of inventory accounting had been used by the Company for inventories valued at LIFO, inventories would have been $873,393 and $949,207 higher than reported at June 30, 2005 and 2004, respectively. The Company did not maintain any work-in-process inventories at June 30, 2005 and June 30, 2004.

31

The components of inventories at June 30 are as follows:

	2005		2004
Raw materials	$	3,254,155	$	1,630,651
Finished goods		4,341,648		5,684,708
Total	$	7,595,803	$	7,315,359

DISTRIBUTION NETWORK—The Company includes inbound freight charges, purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs, and other costs of distribution in the “cost of goods sold” line item.

EQUIPMENT AND LEASEHOLD IMPROVEMENTS—Depreciation is provided on a straight-line basis over the estimated useful life of the asset as follows:

Leasehold improvements	10-15 years
Machinery, equipment, furniture, and fixtures	3-10 years
Tools, dies, molds, and patterns	4-5 years

RESEARCH AND DEVELOPMENT—Research and development expenditures charged to operations amounted to approximately $173,000 in 2005, $125,000 in 2004, and $134,000 in 2003.

SHIPPING AND HANDLING FEES AND COSTS—Shipping and handling fees charged to customers are included in net sales, and shipping and handling costs incurred by the Company are included in cost of goods sold within the accompanying consolidated statements of income.

FAIR VALUE OF FINANCIAL INSTRUMENTS—Cash, accounts receivable, and accounts payable recorded in the consolidated balance sheets approximate fair value based on the short maturity of these instruments.

USE OF ESTIMATES—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

NEW ACCOUNTING PRONOUNCEMENTS—During May 2003, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity,” which establishes standards for the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. The Company adopted SFAS No. 150 effective July 1, 2003. Upon adoption, the Company recorded a derivative liability for the fair value of a written put option of $125,000 on the balance sheet and a cumulative effect of change in accounting principle of $75,875 (net of the tax effect equal to $49,125) on the income statement.

During December 2004, the FASB issued SFAS No. 123R, “Share-Based Payments”, which changed the accounting for equity compensation programs. Under SFAS No. 123R, companies that award share-based payments to employees, including stock options, must begin to recognize the expense of these awards in the financial statements at the time the employee receives the award. As allowed by SFAS 123 and SFAS 148, the Company elected to follow APB Opinion No. 25 in accounting for its stock option

32

plan until the effective date of SFAS 123R. The accounting as provided by SFAS 123R will be effective for the Company beginning July 1, 2005, which is the beginning of the Company’s next fiscal year.

Under APB 25’s intrinsic value method, no compensation cost for employee stock options is recognized. Accordingly, the adoption of SFAS 123R’s fair value method will have an impact on the Company’s results of operations, although it will not have an impact on the overall financial position. The impact of the adoption of SFAS 123R will depend on levels of share-based payments granted in the future and is expected to reduce pre-tax earning by approximately $330,000 in fiscal 2006. SFAS 123R also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under the current standards. This requirement will reduce the net cash provided by operating activities and increase the net cash from financing activities in periods after adoption. While the Company cannot estimate what these amounts will be in the future because it will depend on, among other things, when employees exercise stock options, the amount of cash flows from operating activities in prior periods for such excess tax deductions were approximately $105,000, $330,000 and zero in fiscal years 2005, 2004 and 2003, respectively.

RECLASSIFICATIONS—Certain amounts in the prior year financial statements have been reclassified to conform to current year presentation.

STOCK-BASED COMPENSATION—At June 30, 2005, the Company has a stock-based employee compensation plan, which is described more fully in Note 4. The Company accounts for this plan under the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. All options granted under the plan had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of FASB Statement No. 123, Accounting for Stock-Based Compensation, to stock-based employee compensation.

Year Ended June 30,	2005		2004		2003
Net income, as reported	$	4,493,827	$	5,372,272	$	4,169,411
Add: Total stock-based employee compensation recorded		104,749		330,019		351,764
Deduct: Total stock-based employee compensation expense determined under fair value based method for all awards outstanding		341,192		531,403		447,679
Pro forma net income	$	4,257,114	$	5,170,888	$	4,073,496
Earnings per share:
Basic—as reported	$	1.21	$	1.43	$	1.14
Basic—pro forma	$	1.15	$	1.37	$	1.11
Diluted—as reported	$	1.14	$	1.37	$	1.08
Diluted—pro forma	$	1.08	$	1.32	$	1.06

2. EARNINGS PER COMMON AND COMMON EQUIVALENT SHARE

Basic earnings per share are computed based on the weighted average number of common shares outstanding. The weighted-average number of common shares outstanding for the fiscal years ended June 30, 2005, 2004, and 2003, were 3,711,821, 3,769,033, and 3,671,585, respectively. When dilutive, stock options are included in earnings per share as share equivalents using the treasury stock method. Common stock equivalents of 226,787, 158,657, and 173,010 related to stock option grants were included in the computation of the weighted-average number of shares outstanding for diluted earnings per share for the fiscal years ended June 30, 2005, 2004, and 2003, respectively.

33

3. CREDIT FACILITY

The Company amended its existing credit facility in November 2003, extending the maturity date of the unsecured line of credit to November 1, 2005.

4. STOCK OPTIONS AND STOCK PURCHASE AGREEMENTS

In 1990, pursuant to the recommendation of the Board of Directors, the stockholders ratified the creation of the Company’s 1990 Flexible Incentive Plan (the “1990 Plan”). The 1990 Plan is administered by a committee of the Board of Directors and provides for the granting of various stock-based awards including stock options to eligible participants, primarily officers and certain key employees. A total of 225,000 shares of common stock were available in the first year of the Plan’s existence. Each year thereafter additional shares equal to .25% of the shares outstanding as of the first day of the applicable fiscal year were reserved for issuance pursuant to the 1990 Plan. On July 22, 1992, the Board of Directors authorized the reservation of an additional 250,000 shares for the 1990 Plan, which was approved by the stockholders. In 1993, the Board of Directors authorized the reservation of an additional 300,000 shares for the 1990 Plan, which was approved by the stockholders. In 1997, the Board of Directors authorized the reservation of an additional 300,000 shares for the 1990 Plan, which was approved by the stockholders. In 2001, the Board of Directors authorized the reservation of an additional 300,000 shares for the 1990 Plan, which was also approved by the stockholders. Options generally vest at 25% each anniversary date after grant, with a maximum term of five to ten years.

The following table identifies options granted, exercised, cancelled, or available for exercise pursuant to the above mentioned Plan:

				Range of Exercise		Weighted
	Number of			Prices per		Average

Shares under option at June 30, 2005		765,000		$	5.10—$24.21	$	18.87

The range of options as of June 30, 2005 is as follows:

34

					Weighted Average
	Number of Options		Weighted Average Exercise		Remaining
	Outstanding/Exercisable		Price Outstanding/Exercisable		Contractual Life (In Years)
$  5.10 — $  6.73		27,500 / 27,500	$	5.97 / $5.97		4.1
$15.75 — $18.48		487,500 / 360,625	$	17.41 / $17.55		4.0

			$	18.87 / $17.62

There were no options granted in 2005. The weighted-average fair value at date of grant for options whose exercise price exceeded the market price of the stock on the grant date during 2004 and 2003 was $4.56 and $3.69, respectively. There were no options granted in 2004 or 2003 for which the exercise price was less than the market price on the date of grant. The weighted-average fair value at date of grant for options whose exercise price was equal to the market price of the stock on the grant date during 2004 and 2003 was $2.87 and $5.94, respectively. As of June 30, 2005, the weighted-average remaining contractual life of all outstanding options approximates 4.21 years.

For the pro forma information disclosed in Note 1, the fair value of each option granted is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	2005			2004			2003
Expected stock price volatility		35.00	%		35.00	%		43.40	%
Risk free interest rate		3.69	%		3.69	%		2.84	%
Expected dividend yield		2.27	%		2.27	%		3.30	%
Expected life of options		4.21	years		5.21	years		5.33	years

The Company has an agreement with its Chairman, John C. Koss, in the event of his death, at the request of the executor of his estate, to repurchase his Company common stock from his estate. The Company does not have the right to require the estate to sell stock to the Company. As such, this arrangement is accounted for as a written put option with the fair value of the put option recorded as a derivative liability. The fair value of the option at June 30, 2005 and 2004 was $125,000. The repurchase price is 95% of the fair market value of the common stock on the date that notice to repurchase is provided to the Company. The total number of shares to be repurchased will be sufficient to provide proceeds which are the lesser of $2,500,000 or the amount of estate taxes and administrative expenses incurred by the Chairman’s estate. The Company may elect to pay the purchase price in cash or may elect to pay cash equal to 25% of the total amount due and to execute a promissory note for the balance, payable over four years, at the prime rate of interest. The Company maintains a $1,150,000 life insurance policy to fund a substantial portion of this obligation.

5. INCOME TAXES

The Company utilizes the liability method of accounting for income taxes. The liability method measures the expected income tax impact of future taxable income and deductions implicit in the consolidated balance sheets. The provision for income taxes in 2005, 2004, and 2003 consists of the following:

Year Ended June 30,	2005			2004		2003
Current:
Federal	$	2,527,001		$	2,888,401	$	2,170,101
State		486,000			488,000		501,000
Deferred		(111,000	)		140,629		24,000
	$	2,902,001		$	3,517,030	$	2,695,101

35

The 2005, 2004, and 2003 tax provision results in an effective rate different than the federal statutory rate due to the following:

Year Ended June 30,	2005		2004		2003
Federal income tax at statutory rate	$	2,514,582	$	3,048,160	$	2,333,934
State income taxes, net of federal tax Benefit		354,247		371,531		331,000
Other		33,172		97,339		30,167
Total provision for income taxes	$	2,902,001	$	3,517,030	$	2,695,101

Temporary differences which give rise to deferred income tax assets and liabilities at June 30 include:

	2005			2004
Deferred Income Tax Assets:
Deferred compensation	$	157,000		$	204,000

The retirement payments are to be paid monthly to the officer until his death and then to his surviving spouse monthly until her death. The Company has a deferred compensation liability of $561,165 and $465,265 recorded as of June 30, 2005 and 2004, respectively.

LICENSOR will not unreasonably withhold approval required by LICENSOR under this Section 5.1.

     5.2 LICENSEE agrees to protect, indemnify and save harmless LICENSOR, LICENSOR’s parent, subsidiaries and affiliates and all officers, directors, agents, employees and representatives thereof, from and against any and all expenses, damages, claims, suits, actions, judgments and costs whatsoever, including reasonable attorneys’ fees, arising out of, or in any way connected with, any claim or action relating to the contents of LICENSEE’s advertising or of the Licensed Products, whether or not approved by LICENSOR hereunder, but not including claims that the Licensed Trademarks infringe a third party’s intellectual property rights.

     5.3 LICENSOR has the right to include a full line catalog of LICENSOR’s products within each Product to which the Licensed Trademarks are affixed and distributed by LICENSEE.

     6.5 LICENSEE’s payment of all Royalties must be in United States dollars. The late payment of any Royalties will bear interest at the rate of one and one-half percent (1-1/2%) per month, or at the highest rate permitted by applicable state law, whichever is lower.

7. BOOKS, RECORDS, AND STATEMENTS.

     7.1 LICENSEE shall maintain for three (3) years following the close of each Contract Year accurate books and records that disclose, at a minimum, the following: the cost of sales of the Licensed Products, the amount of sales of the Licensed Products, the amount of credits for returns, trade discounts and customers’ shipping costs, the amount of all Royalties payable hereunder by LICENSEE and the manner in which such Royalties were determined.

     7.2 LICENSEE shall deliver to LICENSOR with each quarterly payment a detailed accounting statement showing the calculation of such Royalties payment. Such statement must be in sufficient detail to be audited from the books of LICENSEE maintained pursuant to Section 7.1. By the 15th day of each month during each Contract Year during the term of this Agreement, LICENSEE shall also provide LICENSOR with a preliminary tabulation of the sales and returns by customer and by Product model number for the prior month, for LICENSOR’s use and analysis.

     7.3 Within ninety (90) days after the close of each Contract Year, LICENSEE shall furnish to LICENSOR a statement, certified to be true and correct by LICENSEE’s Chief Financial Officer, that the accounting for sales is complete and correct, and the total sales of the Licensed Products to each retail account.

     7.4 LICENSOR, at its expense, has the right at any time during regular business hours after the end of any Contract Year, upon five (5) days written notice to LICENSEE, to have a representative of LICENSOR examine or audit the books, accounts and records of LICENSEE that pertain to the manufacture, distribution and sale of the Licensed Products and the amount of credit for returns, trade discounts and customers’ shipping costs with respect thereto, and other books and records as they may be reasonably required by LICENSOR’s accountants to verify the figures reported in any statements furnished to LICENSOR pursuant to this Section 7. LICENSEE shall make such books of account and records available to LICENSOR and its accountants at LICENSEE’s office located as herein stated or such other place as the parties mutually agree. LICENSEE shall render all possible assistance to LICENSOR and its accountants for the purpose of facilitating the checking or auditing of net sales and of the figures set forth in any of LICENSEE’s statements. If the examination or audit reveals the underpayment of any Royalties, LICENSEE shall immediately pay LICENSOR the amount of the deficiency with interest, and if the deficiency exceeds five percent (5%) of the amount of Royalties paid with respect to such year or years audited, LICENSEE shall pay the cost of the examination or audit.

8. TRADEMARKS.

Only LICENSOR has the right to commence legal proceedings against such infringer. In any infringement action, proceeding or claim brought by LICENSOR, LICENSEE, at its expense, shall make available to LICENSOR any relevant books, records, papers, information, designs, samples, specimens, and the like and shall cause any of LICENSEE’s employees to be deposed or to testify, whenever requested to do so by LICENSOR.

10. INDEMNIFICATION AND INSURANCE.

Within 30 days of its receipt of such notice, the defaulting party shall cure the default. If the defaulting party does not take such corrective actions or cure the default within 30 days, the non-defaulting party has the right to terminate this Agreement by providing written notice to the defaulting party. The right to remedy a default does not apply to LICENSEE’s breach of Sections 4, 5, 6 or 7 of this Agreement, which will give LICENSOR the right to treat such breach as a non-curable default and to terminate this Agreement.

(a)	If the other party becomes insolvent or makes an assignment for the benefit of creditors or becomes the subject of receivership, bankruptcy or other insolvency or debtor relief proceedings, or any similar proceedings;

(c)	Except as permitted under Section 14 below, if the other party attempts to assign any of its rights under this Agreement.

     11.3 LICENSEE has the right to terminate this Agreement at any time by giving written notice to LICENSOR during the course of any Contract Year, in which case this Agreement will continue in full force and effect for an additional one (1) Contract Year after December 31 of the Contract Year in which the notice of termination was given. The Minimum Quarterly Royalties in effect at the time of the notice of termination will remain constant for the remaining Contract Years of this Agreement.

In the event of such notice of termination from LICENSOR, this Agreement will continue in full force and effect for an additional one (1) Contract Year after December 31 of the Contract Year in which the notice of termination was given. The Minimum Quarterly Royalties in effect at the time of the notice of termination will remain constant for the remaining Contract Years of this Agreement.

     11.5 No assignee for the benefit of creditors, receiver, liquidator, trustee in bankruptcy, sheriff or any other officer of the court or official charged with taking over custody of LICENSEE’s assets or business, has any right to continue performance of this Agreement, and this Agreement may not be assigned by operation of law.

     11.6 Failure to terminate this Agreement pursuant to this Section 11 does not effect or constitute a waiver of any remedies the non-defaulting party is entitled to demand, whether by way of damages, termination or otherwise. Termination of this Agreement is without prejudice to the rights and liabilities of either party to the other in respect of any matter arising under this Agreement.

12. RIGHTS AFTER TERMINATION.

     12.1 Except as provided in Section 12.2 below, from and after the termination of this Agreement, whether because of non-renewal, default or otherwise, all of the rights of LICENSEE to the use of the Licensed Trademarks will, except as hereinafter expressly provided, cease absolutely, and LICENSEE must not thereafter manufacture, advertise, promote, distribute or sell any item in connection with the Licensed Trademarks. It is further agreed that following such termination, LICENSEE shall not manufacture, advertise, promote, distribute or sell any item in connection with the use of any name, figure, design, logo, trademark or trade name similar to or suggestive of the Licensed Trademarks.

     12.2 Notwithstanding Section 12.1 above, so long as LICENSOR does not terminate this Agreement as set forth in Sections 11.1 and 11.2 above, any Licensed Products for which as of the date of any other termination LICENSEE has non-cancelable open orders may be sold by LICENSEE on a non-exclusive basis during the 9-month period following the date of termination. LICENSEE shall continue to pay Royalties to LICENSOR with respect to such sales at the rate and in the manner specified in this Agreement.

In the event of the merger or consolidation of LICENSEE with any other entity, LICENSOR has the right to terminate this Agreement by so notifying LICENSEE in writing on or before sixty (60) days after LICENSOR has received written notice of such merger or consolidation.

15. INDEPENDENT CONTRACTORS.

     The relationship of LICENSOR and LICENSEE established by this Agreement is that of independent contractors, and nothing contained in this Agreement will be construed to (a) give either party the power to direct and control the day-to-day activities of the other, (b) constitute the parties as partners, joint venturers, co-owners, or otherwise as participants in a joint or common undertaking, or (c) allow LICENSEE or LICENSOR to create or assume any obligation on behalf of the other party for any purpose whatsoever, unless otherwise expressly provided in this Agreement.

16. CONFIDENTIALITY.

     16.1 Definition of Confidential Information. Each party may receive (the “Recipient”) confidential or proprietary information from the other party (the “Disclosing Party”) in the course of performing its obligations under this Agreement. Confidential information includes the terms of this Agreement and any information from the Disclosing Party that: (i) is marked as “Confidential” or “Proprietary,” (ii) is reasonably identifiable as the confidential information of the Disclosing Party, (iii) is not generally known in the businesses and industries in which the Recipient is engaged, or (iv) under the circumstances of the disclosure should reasonably be considered as confidential or proprietary information of the Disclosing Party. Confidential information does not include any information that is: (a) rightly and lawfully known to the Recipient before receipt from

the Disclosing Party; (b) publicly available through no fault of the Recipient; (c) rightly and lawfully received by the Recipient from a third party without a duty of confidentiality; or (d) independently developed by the Recipient without use of or access to the Disclosing Party’s confidential information.

     16.2 Obligations of Confidentiality. Both parties will take reasonable care, but in no event less care than the party uses to protect its own confidential information, to preserve in strict confidence any confidential or proprietary information obtained by them, their agents or employees. Each party will use the confidential information only in the course of performing its obligations under this Agreement, unless otherwise agreed to by the Disclosing Party in writing. Disclosure of confidential information required by a government body or court of law is not a violation of this Section 16 if the Recipient gives prompt notice of the required disclosure to the Disclosing Party (and a reasonable opportunity for the Disclosing Party to obtain a protective order) and the Recipient discloses only the amount of confidential information required to comply with the government body or court of law.

     16.3 Obligations Upon Termination. Each party shall at its own expense return to the other party or otherwise dispose as the Disclosing Party may instruct, any information sent by the Disclosing Party (including electronically sent) to the Recipient.

     17.3 If and to the extent that any provisions of this Agreement are prohibited or unenforceable under any applicable law, such provisions shall be ineffective to the extent of such prohibition or unenforceable without invalidating the remaining provisions hereof or affecting the validity or enforceability of any other provision hereof.

     17.4 The failure of either party at any time or times to demand strict performance by the other of any of the terms, covenants or conditions set forth herein shall not be construed as a continuing waiver or relinquishment thereof and each may at any time demand strict and complete performance by the other of said terms, covenants and conditions.

     17.5 This Agreement is governed by the substantive laws of the State of Wisconsin (regardless of laws that might be applicable under principles of conflicts of laws) as to all matters, including but not limited to matters of validity, construction, effect and performance. Resolution of any and all disputes between LICENSOR and LICENSEE arising from or in connection with this Agreement, whether based on contract, tort, common law, equity, statute, regulation, order or otherwise, will be governed by and settled in accordance with binding arbitration by three (3) arbitrators; provided, however, that the three arbitrators selected must each have extensive knowledge in the area of federal trademark law. If the parties cannot agree on the selection of three arbitrators, each party shall select one arbitrator, and those two

arbitrators together shall select the third arbitrator, and the three arbitrators, shall resolve the dispute as provided herein. The arbitrators’ findings and decisions must be limited to the subject matter of the dispute, and such findings and decisions must be in writing and are final and binding on the parties hereto, and must specify the reasons for and facts on which such findings and decisions were reached. The parties hereto shall bear equally the arbitrators’ fees and charges, and each party shall bear its other costs and expenses for the arbitration, including attorneys’ fees. The arbitration must be conducted in Milwaukee, Wisconsin.

     17.6 No delay, failure or default in performance of any obligation by either party will constitute a breach of this Agreement to the extent caused by an act of God, natural disaster, civil disturbance or other cause beyond the party’s reasonable control and that the party could not have prevented by reasonable precautions. If a force majeure event prevents LICENSEE from performing under this Agreement for more than 90 days, LICENSOR may terminate this Agreement by providing written notice of such termination to LICENSEE.

     IN WITNESS WHEREOF, each party hereto has caused this Agreement to be executed as of the Effective Date.
