July 15, 2003

SANTA CRUZ, CA - July 15, 2003 - Plantronics, Inc. (NYSE: PLT) today announced revenues and earnings for its first quarter of fiscal year 2004. First quarter revenues increased approximately 15.5% to $92.8 million, in comparison to $80.3 million in the first quarter of fiscal 2003, and operating income increased from $13.6 million to $15.7 million. First quarter net income was $11.3 million compared to net income in the first quarter of fiscal 2003 of $10.2 million. Plantronics' diluted earnings per share increased 19% to $0.25 in comparison to $0.21 in the first quarter of fiscal 2003.

Ken Kannappan, President and Chief Executive Officer, noted, "Our results were generally in line with the high end of the guidance we issued on April 22, which called for revenues of $87 to $91 million, and earnings per share of $0.21 to $0.25. In comparison to the June quarter last year, all product groups exhibited some revenue growth with the largest increase coming from new headsets for mobile phones. Our Walker business, which includes products for the hearing-impaired sold under the brand names Walker, Clarity and Ameriphone, also grew solidly and turned in its best quarter ever on the strength of demand from state programs."

"In addition to our solid financial performance, I am very pleased with the progress we made pursuing our vision of enhancing personal communications with wireless headset technologies. During the quarter, we had in-depth meetings with our channel partners worldwide as well as with our sales teams, receiving first hand feedback on our new products, our product and technology roadmaps, and our associated marketing programs. The response was enthusiastic and revenues from new products that commenced shipping in the June quarter exceeded our expectations. For example, we launched the MX-150 mobile headset, based on our award-winning MX-100 design, and incorporated noise canceling technology to further enhance clarity in loud environments. The MX-150 demonstrates the principle of design efficiency and re-use that we have been working to achieve. This product was ramping even while sales of the MX-100 were also growing," Kannappan continued.

"While our internal work is less visible, we also continue to focus on improving efficiency and productivity. We elected to transition early to the new ISO 9000 - 2000 edition of the standard and worked to ready ourselves for the required comprehensive audits. Both the Santa Cruz headquarters as well as our manufacturing plants in Mexico passed these audits in June with the auditor commenting that Plantronics is doing better work than most other companies. This is only one part of the work we have underway to enable us to remain highly efficient, competitive, and able to deliver outstanding products and services to our customers at a fair price while earning good returns for our shareholders," Kannappan concluded.

Barbara Scherer, SVP and CFO, said "I'm pleased with our financial performance, particularly the level of cash flow from operations which amounted to $17.7 million. Cash collections on accounts receivable were excellent, and as a result, DSO dropped to 48 days from 52 in the March quarter. This is an unusually low level and we anticipate some growth in DSO in the September quarter. Inventory increased and inventory turns decreased somewhat from 5.3 at fiscal year-end to 5.0 as of the end of June. The increase in inventory was anticipated and was primarily the result of preparing for the launch of several new products this summer, as well as taking precautions in the event of SARS-related slowdowns in the supply chain."

During the quarter, we repurchased 122,800 shares of our common stock for approximately $1.8 million and had 142,600 shares remaining authorized for repurchase as of the end of the quarter. Although we intend to continue to repurchase stock, we note that the stock has been trading above the levels authorized for repurchase by our Board. A price cap on stock repurchase is set to help ensure that purchases of stock by the company are reasonably strongly accretive to earnings per share. The level of stock repurchase by the company has fluctuated in the past, and is likely to fluctuate substantially in the future as well. We continue to view stock repurchase programs as an important long-term use of excess cash flow.

Business Outlook

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

We recognize that although certain economic indicators have improved, the overall economic and geopolitical environment remain challenging and highly uncertain. Although we are cautiously optimistic about our own outlook primarily on the basis of expected demand for new products, we remain uncertain about the overall level of demand for our products and consequently, our level of future profitability. In particular, employment levels have not yet risen and we believe our business is heavily influenced by the level of employment and the percentage of workers unemployed. Related to this, our U.S. commercial distributors of contact center and office products reported a 5% decrease in the sell-through for the June quarter in comparison to the March quarter, and a 4% decrease compared to the year-ago comparable quarter.

Although we remain uncertain about the economic environment and see no signs of a pick-up in the contact center market, we are currently expecting:

• Revenues for the second quarter of fiscal 2004 to be in the range of $92 - $97 million.
• Earnings per share for the second quarter of fiscal 2004 to be in the range of $0.24 - $0.27.

Plantronics does not intend to update these targets and estimates during the quarter or to report on its progress toward these estimated results. Plantronics will not comment on these targets to analysts or investors except through publicly announced conference calls, press releases or other public disclosure. Any statements by persons outside Plantronics speculating on the progress of the quarter 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 projections of revenues and earnings for the September quarter, and our current expectations regarding market acceptance of new products and improved manufacturing efficiency and productivity, 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 further slowing in national or international economic growth or a "double-dip" recession resulting in a reduction in the overall level of demand for our products;
• A lessening 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;
• If the national/international economy recovers, 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;
• 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;
• Greater sales in higher tax jurisdictions as compared to lower tax jurisdictions;
• Fluctuations in foreign exchange rates;
• 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; and
• The impact on the U.S. economy due to the aftermath of the war with Iraq and geopolitical risk factors in the Middle East and North Korea.

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 or our contract manufacturing operations in China, further terrorist acts, our nations' response to terrorist attacks and the effects of these activities on capital and consumer spending, the effects of the "do not call" legislation may have a greater impact than we currently anticipate, and the loss of 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.
