July 20, 2004

SANTA CRUZ, CA. – July 20, 2004 - Plantronics, Inc., (NYSE: PLT) today announced record financial results for its first quarter of fiscal year 2005. First quarter revenues increased approximately 42% to $131.4 million to a new quarterly record, in comparison to $92.8 million in the first quarter of fiscal 2004. Operating income increased to $30.7 million from $15.7 million, net income increased to $22.3 million from $11.3 million, and diluted earnings per share improved to $0.44 from $0.25, in each case from the year-earlier quarter.

Ken Kannappan, President and Chief Executive Officer, noted, "We are excited about the growing adoption of Plantronics headsets by people for use in all aspects of their lives which is apparent in our financial performance. The opportunity for wireless freedom resonates with people and we remain focused on delivering that promise. I’m also happy to report that sales of contact center headsets appeared to strengthen as evidenced by sales of our recently introduced SupraPlus™ telephone headset family.”

Our results were above the guidance provided on April 27th, which called for revenues of $120 to $125 million, and earnings per share of $0.37 to $0.41, principally due to revenues from mobile headsets increasing more than we expected, coming in at $34.5 million for the quarter compared to $25.9 million in the March quarter and $18.5 million in the year-earlier quarter. Mobile headset revenues were stronger than we anticipated as a result of U.S. carrier market share in corded headsets for bundles maintaining levels that we continue to believe are unsustainably high and which, in fact, we expect will correct to a more normal level in the September quarter.

“Revenues from our Office and Contact Center products were $82.8 million, up 33% vs. the year-earlier quarter and up approximately 2%, or $2 million, sequentially,” noted Kannappan. In comparison to the year-earlier quarter, the growth resulted primarily from the adoption of our wireless headsets for business professionals as well as continuing evidence of some rebound in revenues of contact center products. First quarter revenues from wireless headsets for the office, namely the CS50 and CS60, continued at about the same pace as the March quarter. In comparison to the March quarter, the 2% sequential growth in Office and Contact Center products overall was the result of the success of the SupraPlus™ telephone headset family. The initial shipments of this product took place in March but the global volume launch of this innovative and stylish new headset for contact center agents took place in the first quarter with positive results. We also saw growth in a number of accounts globally that serve the contact center market,” Kannappan continued.

“Technology advances and market trends have merged, accelerating opportunities for communications headsets. The company that successfully captures these opportunities will be a technology leader and a design innovator. Plantronics is poised to strengthen its leadership position further. We have continually increased investments in emerging technologies and we’ve recently increased our emphasis on design, style, customer research and marketing. For example, yesterday we announced the addition of a highly talented Chief Marketing Officer to the management team. We believe that these investments, coupled with our 43 years of experience in the market, give us the tools needed for success,” said Kannappan.

Barbara Scherer, SVP and CFO, said, "Working capital management was solid in a quarter with ramping demand, as inventory turns held steady at 5.2 and DSO improved to 47 days in the June quarter from 52 days in the March quarter. We also generated $33.5 million in cash flow from operations and our cash balance increased from $180.6 million at the end of fiscal 2004 to $211 million at the end of the June quarter.”

Business Outlook

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

We remain cautiously optimistic about the overall economic environment and demand for our products. We feel that caution remains warranted given concern about recent signs of a slowdown in the rate of U.S. GDP growth, the level of unemployment in the United States, the level of budget and trade deficits in the United States, the impact of a weak dollar on the U.K. and Euro region economies and ongoing tensions in the Mid-East. Given these and other factors, we remain uncertain concerning the strength and sustainability of the economic environment and the related outlook for headset demand.

An important factor in our outlook for the September quarter is our belief that our share of mobile headsets used in promotional offers, typically referred to as a “bundle” in the U.S. wireless carrier market, will return to historically normal levels this quarter after several quarters of what has been unusually high market share for us. We also believe that the inventory build that was needed by our customers to support these bundles was largely a one-time event that favorably affected our revenues in Q1. We believe that the target level of inventory was attained in the June quarter and that no further increase in inventory by those customers will be needed in the September quarter. We currently believe these effects will account for about a $6 - 7 million revenue decrease from the June quarter to the September quarter. However, we currently expect growth in other parts of the mobile business, particularly Bluetooth headsets for international markets, to offset most of the sequential decline in corded products used in bundles in the U.S. carrier market.

We also consider the trends in sell-through of our U.S. commercial distributors of office and contact center products an important indicator of demand. For the March quarter, this group of distributors reported to us an increase in sell-through of 24% in comparison to the March quarter last year, and a 4% decrease sequentially. In comparison to a year ago, our analysis indicates that the largest driver in the increased sell-through was demand for the CS50, our wireless headset solution for the office market, although we also saw increased sell-through in products and channel partners that primarily use and serve the contact center market. On a sequential basis, there is no definitive trend; most product lines exhibited slightly lower sell-through. Our level of revenues to this channel closely matched their level of reported sell-through with channel inventory levels therefore remaining largely unchanged.

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 current expectations are:

• Revenues for the second quarter of fiscal 2005 to be in the range of $124-$130 million. Assuming we achieve $124 to $130 million in revenues, the growth vs. Q2 fiscal 2004 will be approximately 30% to 37%. In comparison to the first quarter of fiscal 2005, this level of revenues would result in a 1% to 6% sequential decline.
  
  We currently believe that revenues from most product lines will be fairly similar in the September quarter to that of the June quarter, except that we expect mobile products to decline somewhat sequentially as mentioned earlier in this press release.

• Earnings per share for the second quarter of fiscal 2005 to be in the range of $0.42 - $0.46.

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 second quarter fiscal year 2005 results or by other public disclosure. Any statements by persons outside Plantronics speculating on the progress of the second 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

This release contains forward-looking statements within the meaning of Section 27A of the Securities Exchange Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Specific forward-looking statements include our outlook for revenues and earnings for the second quarter of fiscal 2005; that mobile revenues are expected to decline in the September quarter; and our cautious optimism about the overall economic environment and the demand for our products. These forward-looking statements involve a number of risks and uncertainties, and are based on current expectations, forecasts and assumptions.

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.
• 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 May 26, 2004, filings on Form 10-Q and other filings with the Securities and Exchange Commission as well as recent press releases.
