Accounting Policies [Abstract]
Basis of Consolidation	BASIS OF CONSOLIDATION — The consolidated financial statements include the accounts of Koss and its subsidiary, Koss UK, which is a 100%-owned subsidiary. All significant intercompany accounts and transactions have been eliminated.
Revenue Recognition	REVENUE RECOGNITION — Revenue is recognized by the Company upon shipment of product, which is generally when title passes to the customer, the price is fixed and collectibility is reasonably assured. Provisions for slotting fees, cooperative advertising programs, rebates, sales discounts, estimated returns and allowances, and other estimated costs are provided for in the same period the sales are recorded. These provisions are recorded as a reduction to sales.
Shipping and Handling Fees and Costs	SHIPPING AND HANDLING FEES AND COSTS — Shipping and handling costs charged to customers have been included in net sales. Shipping and handling costs incurred by the Company have been included in cost of goods sold.
Research and Development	RESEARCH AND DEVELOPMENT — Research and development activities charged to operations as a component of selling, general and administrative expenses in the accompanying Consolidated Statements of Operations amounted to $1,024,885 in fiscal year 2014 and $1,436,493 in fiscal year 2013.
Advertising Costs	ADVERTISING COSTS — Advertising costs included within selling, general and administrative expenses in the accompanying Consolidated Statements of Operations were $211,196 in 2014 and $230,455 in 2013. Such costs are expensed as incurred.
Income Taxes	INCOME TAXES — The Company operates as a C Corporation under the Internal Revenue Code of 1986, as amended (the “Code”). Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed annually for differences between the financial statements and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred income tax assets and liabilities are adjusted through the provision for income taxes. The differences relate principally to different methods used for depreciation and amortization for income tax purposes, net operating losses, capitalization requirements of the Code, allowances for doubtful accounts, stock-based compensation, warranty reserves, and other income tax related carryforwards. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized.
Income (Loss) Per Common Share	INCOME (LOSS) PER COMMON AND COMMON STOCK EQUIVALENT SHARE — Income (loss) per common and common stock equivalent share is calculated under the provisions of Topic 260 in the Accounting Standards Codification ("ASC") which provides for calculation of “basic” and “diluted” income (loss) per share. Basic income (loss) per common and common stock equivalent share includes no dilution and is computed by dividing net income by the weighted average common shares outstanding for the period. Diluted income (loss) per common and common stock equivalent share reflects the potential dilution of securities that could share in the earnings of an entity.
Cash and Cash Equivalents	CASH AND CASH EQUIVALENTS — The Company considers depository accounts and investments with a maturity at the date of acquisition and expected usage of three months or less to be cash and cash equivalents. The Company maintains its cash on deposit at commercial banks located in the United States of America. The Company periodically has cash balances in excess of insured amounts. The Company has not experienced and does not expect to incur any losses on these deposits.
Accounts Receivable	ACCOUNTS RECEIVABLE — Accounts receivable consists of unsecured trade receivables due from customers. An allowance for doubtful accounts is recorded for significant past due receivable balances based on a review of the past due item, general economic conditions and the insurance coverage in place. See Note 3 for additional information on accounts receivable.
Inventories	INVENTORIES — The Company’s inventory was valued at the lower of last-in, first-out (“LIFO”) cost or market. The carrying value of inventory is reviewed for impairment on at least a quarterly basis or more frequently if warranted due to changes in market conditions. See Note 5 for additional information on inventory.
Equipment and Leasehold Improvements	EQUIPMENT AND LEASEHOLD IMPROVEMENTS — Equipment and leasehold improvements are stated at cost. Depreciation and amortization is calculated using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or the estimated useful life of the asset. Major expenditures for property and equipment and significant renewals are capitalized. Maintenance, repairs and minor renewals are expensed as incurred. When assets are retired or otherwise disposed of, their costs and related accumulated depreciation and amortization are removed from the accounts and any resulting gains or losses are included in operations.
Product Software Development Expenditures	PRODUCT SOFTWARE DEVELOPMENT EXPENDITURES — The Company follows the guidance of ASC 985-20 “Costs of Software to be Sold, Leased, or Marketed” when capitalizing software development expenditures associated with software embedded in or to be incorporated into its products. The cost of purchased software technology is capitalized and stated at the lower of unamortized cost or expected net realizable value. At a minimum, we review for impairment on a quarterly basis. Amortization is being recorded over a three year period or a fixed amount per unit sold, whichever is greater. See Note 7 for additional information
Life Insurance Policies	LIFE INSURANCE POLICIES — Life insurance policies are stated at cash surrender value or at the amount the Company would receive in the case of split-dollar arrangements. Increases in cash surrender value are included in selling, general and administrative expenses in the Consolidated Statements of Operations, which is where the annual premiums are recorded.
Product Warranty Obligations	PRODUCT WARRANTY OBLIGATIONS — Estimated future warranty costs related to products are charged to cost of goods sold during the period the related revenue is recognized. The product warranty liability reflects the Company’s best estimate of probable obligations under those warranties. See Note 11 for additional information on product warranty obligations.
Deferred Compensation	DEFERRED COMPENSATION — The Company’s deferred compensation liabilities are for a current and former officer and are calculated based on compensation, years of service and mortality tables. The related expense is calculated using the net present value of the expected payments and is included in selling, general and administrative expenses in the Consolidated Statements of Operations. See Note 12 for additional information on deferred compensation.
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS — Cash equivalents, accounts receivable and accounts payable approximate fair value based on the short maturity of these instruments.
Impairment of Long-Lived Assets	IMPAIRMENT OF LONG-LIVED ASSETS — The Company evaluates the recoverability of the carrying amount of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. The Company evaluates the recoverability of equipment and leasehold improvements annually or more frequently if events or circumstances indicate that an asset might be impaired. If an asset is considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell. Management determines fair value using a undiscounted future cash flow analysis or other accepted valuation techniques. The Company recorded an impairment of capitalized software in the year ended June 30, 2014, detailed in Note 4. No impairments of the Company's long-lived assets were recorded in the year ended June 30, 2013.
Legal Costs	LEGAL COSTS — All legal costs related to litigation are charged to operations as incurred, except settlements, which are expensed when a claim is probable and can be estimated. Recoveries of legal costs are recorded when the amount and items to be paid are confirmed by the insurance company. Proceeds from the settlement of legal disputes are recorded in income when the amounts are determinable and the collection is certain.
Stock-Based Compensation	STOCK-BASED COMPENSATION — The Company has a stock-based employee compensation plan, which is described more fully in Note 15. The Company accounts for stock-based compensation in accordance with ASC 718 "Compensation - Stock Compensation". Under the fair value recognition provisions of this statement, share-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the vesting period.
Use of Estimates	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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	RECLASSIFICATIONS — Certain amounts previously reported have been reclassified to conform to the current presentation.
