January 13, 2004

SANTA CRUZ, CA. - January 13, 2004 - Plantronics, Inc., (NYSE: PLT) today announced revenues and earnings for its third quarter of fiscal year 2004. Third quarter revenues increased 24% to $107.6 million to a new quarterly record, in comparison to $86.8 million in the third quarter of fiscal 2003, and operating income increased 89% from $12.6 million to $23.8 million. Third quarter net income was $17.6 million compared to net income in the third quarter of fiscal 2003 of $9.2 million. Plantronics' diluted earnings per share were $0.37 for the third quarter in comparison to $0.20 in the third quarter of fiscal 2003.

Ken Kannappan, President and Chief Executive Officer, noted, "Our results were above the guidance we issued on October 15th, which called for revenues of $95 to $100 million, and earnings per share of $0.27 to $0.30. Domestic and international revenue growth was led by increased demand for headsets for mobile phones and for wireless headsets in the office. Earnings grew substantially due to higher revenues and an expansion of our profit margins primarily due to the leverage of the higher revenues on our cost structure."

"Revenues from mobile headsets reached $29.5 million, up from $16.1 million in the December quarter a year ago and up from $18.4 million in the September quarter. Within the mobile products group, both corded and Bluetooth™-based headsets were up sharply. While this product category has historically been strong in the December quarter due to seasonality, we believe that additional factors caused demand for our products to be unusually high last quarter. In particular, we believe that our market share may have been unusually strong during the December quarter and that this position is unlikely to be sustainable. Other favorable impacts on demand in the December quarter included the impact of the hands-free legislation in the U.K. and a small effect from wireless number portability in the U.S. For these reasons, we currently anticipate that revenues of mobile products are likely to be lower in the fourth quarter than they were in the third quarter," Kannappan added.

"In the office, the market for wireless products is also growing and the need for such hands-free communication tools led us to develop and introduce the CS50 and CS60 systems. We were very pleased by the growth in revenues for the CS60 during the quarter, and by the initial market acceptance of the CS50 in North America. These innovative wireless headset systems also contributed to the record revenue level and to a 14% year-over-year increase in Office and Contact Center product group revenues," Kannappan concluded.

Barbara Scherer, SVP and CFO, said, "Our overall financial performance was excellent and in fact we exceeded the 20% target for operating margins that we have been working to achieve. The 22.1% operating margin achieved in the December quarter should not be viewed as a sustainable long term metric, although we are increasingly of the belief that we can make the right mix of investments and achieve growth while earning somewhat more than 20%, and we are thus setting our operating margin target for FY2005 as a whole at 21% or better. One of the key factors in our assessment of this target is our likely customer mix which we believe is unlikely to include significant revenues from mobile handset OEMs, particularly for Bluetooth products. For the fiscal 2004 year, we believe that our revenues of Bluetooth headsets for OEM customers will approach $15 million. We continue to see a good opportunity for Plantronics-branded Bluetooth headsets on which we have historically earned higher margins than we have on such products for OEM customers."

"We made good progress on working capital management. Inventory turns improved to 5.2 from 4.9, and DSO of 54 days was excellent for a quarter with such a strong increase in revenues and with the usual slowdown in collections around the holidays. During the quarter, we generated $16.1 million in cash flow from operations and year to date, have generated $48 million. We did not repurchase any shares during the quarter and continue to have 142,600 shares remaining authorized for repurchase. Our cash balance increased from $92.1 million as of the end of the September quarter to $107.3 million as of the end of the December quarter. During the quarter, we purchased land and facilities that we previously leased in Swindon, U.K. The purchase price was approximately $5.6 million and we believe that the purchase will yield an attractive return on investment as well as lower our annual operating costs in comparison to continuing to lease. Looking forward over the next 12 to 18 months, we are planning or considering certain other capital expenditures related to facilities, including an upgrade of our corporate offices in Santa Cruz, a purchase of certain of our manufacturing facilities in Mexico, which are currently leased, and a purchase of land and construction of a factory and development center in China. The potential purchase in Mexico is currently highly uncertain and the planning for China is in a very early stage, and thus the total capital cost of these initiatives is uncertain and could range from $10 to $20 million," Scherer concluded.

Business Outlook

The following statements are based on current expectations. Many of these statements are forward-looking, and actual results may differ materially.

We are more optimistic than we have been for some time about the overall economic environment though still feel that caution is warranted given concern about the level of unemployment in the U.S., the level of budget and trade deficits in the U.S., and the impact of a weak dollar on the Euro region recovery. Given these and other factors, we remain uncertain concerning the strength and sustainability of the economic environment and the related demand outlook for headsets.

We consider the trends in sell through of our U.S. commercial distributors of office and contact center products an important indicator of demand in this key market for us. For the December quarter, this group of distributors reported to us an increase in sell through of 5% in comparison to the December quarter last year, and 1% growth sequentially. We currently anticipate sell through to increase sequentially in March, based on historic patterns and also because our fourth quarter will contain 14 weeks.

We have a "book and ship" business model whereby we ship most orders to our customers within 48 hours of our receipt of those orders, and we thus cannot rely on the level of backlog to provide visibility into potential future revenues. Our visibility is particularly weak in the March quarter. Historically, this quarter has been characterized by a slow start after the holiday period and a stronger finish, the opposite pattern from the December quarter.

Based on all of the foregoing, we are currently expecting:

• Revenues for the fourth quarter of fiscal 2004 to be in the range of $104-$108 million. We expect revenues of mobile communication products to decline sequentially from the record high $29.5 million achieved in the seasonally strong December quarter partially or fully offset by growth in other product lines primarily as a result of a 14 vs. 13-week fourth quarter. On a 13-week basis, the above range would be equivalent to approximately $96 to $100 million.
• Earnings per share for the fourth quarter of fiscal 2004 to be in the range of $0.30 - $0.34. In preparing this guidance, we have estimated that gross margins are likely to be up slightly from the third quarter. Offsetting that positive effect, operating expenses should be higher than the third quarter, primarily as the result of the 14^th week and the associated payroll and other normal recurring costs that we will incur together with the charges we anticipate from the consolidation of our Garden Grove facility with our Chattanooga facility announced yesterday. On a 13-week basis, the above range would be equivalent to approximately $0.27 to $0.30 diluted earnings per share. We are not planning for a balance sheet based foreign exchange gain or loss, which if one occurs, is accounted for in other income and expense below the operating income line. In the third quarter of fiscal 2004, we had an unusually large foreign exchange gain which contributed almost $0.02 to EPS.

Assuming the range of results above for the fourth quarter, results for the full fiscal year are currently expected to be revenues of $399.5 million to $403.5 million and diluted earnings per share of $1.19 to $1.23. Our fiscal 2004 year contains 53 weeks in comparison to 52 in fiscal 2003, with the fourth quarter containing 14 weeks instead of the usual 13, and will end on April 3, 2004. We plan to release earnings for the fourth quarter and full year on April 27, 2004. The extra week in the fourth quarter of fiscal 2004 will affect the comparability with the third quarter of fiscal 2004, the fourth quarter of fiscal 2003, and the comparability of the full fiscal year to both the prior and upcoming fiscal years. The extra week in the fourth quarter can also be expected to negatively affect the comparison between the fourth quarter of fiscal 2004 and the first quarter of fiscal 2005 because the extra week in the fourth quarter is likely to contribute $7 to $8 million of revenue which would not recur in the first quarter.

Plantronics does not intend to update these targets during the quarter or to report on its progress toward these targets. Plantronics will not comment on these targets to analysts or investors except by its next press release announcing its fourth quarter and fiscal year 2004 results or by other public disclosure. Any statements by persons outside Plantronics speculating on the progress of the fourth quarter of the fiscal year will not be based on internal Company information and should be assessed accordingly by investors. The statements do not reflect the potential impact of any mergers or acquisitions that may be completed after the date of this release.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995:

Certain statements in this press release, including our potential capital spending plans on facilities, current expectations and projections for revenues and earnings for the March quarter and full 2004 fiscal year, our target for operating margins, and other statements under the caption "Business Outlook" above, are forward-looking statements based on current information and expectations. Achievement of the results projected above is subject to a number of risks and uncertainties. Among the factors that could cause actual results to differ materially from those projected are:

• A slowing in national or international economic growth, resulting in a reduction in the overall level of demand for our products;
• As the national and international economies recover, employment opportunities in the contact center or office markets may not increase commensurately but may remain flat or even decrease, lessening the future demand for our products;
• A softening of the level of market demand for our products within our core contact center market and/or in the newer office, mobile, computer and residential markets;
• The inability to successfully develop, manufacture and market new products.
• The demand for new wireless headset products may not develop as we anticipate and may lead to excess inventory and the inability to recover the associated development costs.
• A decrease in the liquidity of our customers caused by general economic conditions that may impact their ability to pay amounts due us;
• The actions of existing and/or new competitors, especially with regard to pricing and promotional programs;
• The entry of new competitors which could be spurred by changes in the regulatory environment, particularly laws requiring the use of hands-free devices by drivers when using cellular telephones;
• Variations in sales and profits in higher tax, as compared to lower tax, jurisdictions;
• Fluctuations in foreign exchange rates; and
• Changes in the regulatory environment either as to headsets directly or as to the products, such as mobile phones, with which our products are used.

Additional risk factors include: changes in the timing and size of orders from our customers, price erosion, increased requirements from retail customers for marketing and advertising funding, failure to match production to demand, interruption in the supply of sole-sourced critical components, continuity of component supply at costs consistent with our plans, failure of our distribution channels to operate as we expect, failure to develop products that keep pace with technological changes, the inherent risks of our substantial foreign operations, problems which might affect our principal manufacturing facility in Mexico, further terrorist acts, our nation's response to terrorist attacks and the effects of these activities on capital and consumer spending, and the loss of the services of key executives and employees. For more information concerning these and other possible risks, please refer to the Company's Form 10-K filed on June 2, 2003, filings on Form 10-Q and other filings with the Securities and Exchange Commission as well as recent press releases.
