SANTA CRUZ, CA. - March 18, 2004 – Plantronics, the world leader in communications headsets, today announced the SupraPlus headset, the new standard in performance, reliability and all-day wearing comfort for contact center and office professionals. The SupraPlus™ telephone headset family leverages the strength of the market-leading Supra® models and introduces Plantronics’ next generation of durable, comfortable corded headsets. SupraPlus headsets also feature a modern design to match today’s style preferences.

Utilizing more than 40 years of headset design and audio expertise, Plantronics designed SupraPlus from the ground up, expanding on the classic corded headset style and functionality. SupraPlus improves on Plantronics’ popular corded headset line by incorporating new features, such as enhanced receive-side audio quality, intelligent flexible boom and improved stability, into a contemporary design.

With its wider receive-side frequency response curve, SupraPlus provides optimal listening intelligibility, which in turn reduces miscommunications and frustration for both parties on the call. SupraPlus provides excellent audio quality for traditional voice applications as well as the increasingly popular Voice over IP softphone applications.

“Our success over the years with Supra, the most popular headset in the world, gave us great insight into real user needs,” said Peter Zan, senior product marketing manager for Plantronics. “Contact center and office professionals who need a durable headset that can handle the demands of everyday, all-day usage also want it to be comfortable, as well as have a stylish design that reflects their professional image. We developed the SupraPlus to meet this challenge, providing the style and substance they require.”

Specifications, Pricing and Availability

The SupraPlus telephone headset family allows users to select the model that best suits their needs. SupraPlus is available in monaural or binaural models, and offers either noise-canceling or voice tube microphones. The noise-canceling model features an intelligent bendable boom that keeps the microphone properly aligned, even when bent, to permit clear, accurate conversations.

SupraPlus supports Plantronics’ H-Series and Polaris configurations and is compatible with all Plantronics amplifiers, USB-to-headset adapters, and headset-ready phones and agent consoles.

The SupraPlus monaural voice tube model is available now. The other SupraPlus models will be available in early spring 2004 from Plantronics’ distributors and at www.plantronics.com. The H-Series voice tube and noise-canceling models have an MSRP of US$79 – $120; the Polaris voice tube and noise-canceling models have an MSRP of US$115 - $164.
