Plantronics, Inc. (NYSE: PLT) today announced two new Bluetooth(R) headsets, the Plantronics Discovery(TM) 645 and Plantronics Voyager 510 with WindSmart(R), that incorporate new technologies for excellent audio clarity during conversations. The Voyager 510 is the first Bluetooth headset on the market to include both a noise-canceling microphone and wind-reduction technology for brilliant sound in windy environments. The Discovery 645 includes a digital signal processing (DSP) chip to actively reduce background noise when talking.

A recent test of the new Voyager 510 headset by the National Analysis Center, a leading independent testing lab for the wireless phone industry, found that “the Plantronics Voyager 510 Bluetooth headset supports an innovative boom microphone design which greatly minimizes the effects of wind noise. A high level of customer satisfaction should be realized due to the exceptional audio quality along with the ability to use the headset in outdoor windy conditions.” For its superior wind noise performance, the National Analysis Center awarded Voyager 510 with its “Innovation” award.

“As Bluetooth headsets gain in popularity, consumers are using them in every imaginable environment — from the car to night clubs to baseball games,” said Renee Niemi, vice president of Mobile and Entertainment at Plantronics. “By adding advanced sound technologies to the Discovery and Voyager products, we are providing consumers with the best of both worlds: products that look great and sound fantastic, regardless of where they are talking.”

The Plantronics Voyager 510 with WindSmart also features a new stylish black and silver color scheme, and includes multipoint technology for seamlessly switching between two Bluetooth devices. Other product features include:

— Lightweight, foldable design for all-day wearing comfort and easy
storage,
— One-touch call answer/end, last number redial and voice activated
dialing,
— Boom swivels for use on either ear for optional wearing preference,
— Support for Bluetooth headset and hands-free profiles,
— Up to 6 hours talk time and up to 100 hours standby time, and
— Freedom to roam up to 33 feet away from voice-enabled Bluetooth
devices.

The Plantronics Voyager 510 has an estimated street price of US $79 and is available today at http://www.plantronics.com/, as well as Cingular, Fry’s, Office Depot, Radio Shack, and Sprint/Nextel, among others.

dialing,
