Plantronics Unveils Advanced Technology Concepts on Wall Street

Company to Ring New York Stock Exchange Opening Bell and Show Advanced Wireless Headset Concepts

SANTA CRUZ, CA. - June 20, 2003 – Plantronics, Inc. (NYSE-Listed PLT), will ring the opening bell at the New York Stock Exchange today as the company celebrates its new wireless communications products and demonstrates new technologies.

While in New York, Plantronics will offer a glimpse into the future of wireless voice communications by demonstrating two advanced technology concepts that will change how business professionals communicate. As voice and data technologies converge, Plantronics is driving the emergence of a new wireless work style that capitalizes on the growing power of digital voice technology.

Earlier this year, Plantronics announced two new wireless headset products that are designed to meet the ever-changing communications needs of mobile professionals. The two new products, the CS50, a wireless office headset system, and the M3000, a Bluetooth mobile headset, will ship later this year in the U.S.

The CS50 combines hands-free communication with wireless mobility, so users can move freely around the office while carrying on a conversation, or pick up an important call while they're away from their desk. The M3000 is a Bluetooth-compatible wireless mobile headset that offers the best talk time on the market—up to 8 hours—and up to 200 hours of standby time. The CS50 and M3000 set the stage for the Advanced Technology Concepts being demonstrated in New York today.

The two Advanced Technology Concepts feature digital voice technology that will shape the next generation in wireless communications. The demonstrations include a wireless headset and base system for the office with integrated Digital Signal Processing (DSP), softphone compatibility, USB connectivity and Voice over Internet Protocol (VoIP) functionality. The technologies employed in this concept improve sound quality so that speech recognition and voice command programs can achieve much greater accuracy. This allows users to move away from keyboards and dial pads, and instead use their voice to dictate e-mails, initiate telephone calls and execute software commands, whether they're at their desk or down the hall.

The second digital voice technology being demonstrated is a Bluetooth-enabled wireless headsets for mobile users that features exceptional voice clarity. A DSP chip embedded in the headset boosts the user's voice while dramatically reducing background noise, which is particularly important in noisy environments such as airports, cars and city streets.

Although the digital technologies featured in these concepts are only for demonstration, DSP technology will be incorporated into future headsets to deliver superior sound quality in smaller, more discreet designs.

"Over 40 years of headset innovation has brought us to this critical juncture," said Ken Kannappan, President and CEO of Plantronics. "Wireless products with digital sound will let people use their voice to easily dial phone numbers, providing a whole new level of freedom." He added, "Business and personal communications are constantly changing, and Plantronics' plans to lead the market by delivering cutting-edge solutions that enable comfortable, flexible and productive voice communications."

Plantronics is no stranger to the New York Stock Exchange. Many of the traders on the floor of the Exchange use Plantronics hands free headsets for communications as they execute their trades. By ringing the bell today and showcasing advanced technologies, Plantronics marks an important milestone in its journey of developing headsets that enhance both business and personal communications.
