SANTA CRUZ, CA - November 25, 2003 – Plantronics (NYSE:PLT), the world leader in lightweight communications headsets, untethers office professionals from their desks with the release of the CS50 Wireless Headset System, a completely wireless digital headset system. Plantronics’ CS50 enables a hands-free workstyle that suits the needs of today’s busy professionals, enhancing their freedom and efficiency.

The sleek, self-contained design of the wireless CS50 addresses the number one product concern of business professionals who have chosen not to use a headset—they don’t want to be tied to their desk or have a wire in the way (Plantronics study, 2002). With the CS50, office professionals can communicate up to 300 feet away from their desk phone, for up to eight hours. The lightweight headset also uses built-in digital encryption so conversations are secure.

“In a fast-paced, people-powered business like ours, the phone is a powerful and indispensable tool. The CS50 has greatly improved my department’s accessibility and productivity,” said Adam Keen, vice president of special projects for MGM and United Artists. “The CS50’s combination of mobility and comfort enables us to multitask much more effectively. Also, unanswered calls are now a rarity, which means there’s less chance we’ll miss out on something important.”

The CS50’s wireless mobility gives businesses an important competitive advantage. Most workspace is unoccupied for 60% of the workday, and every day more than 70% of business calls are missed (UNWIRED, 2003). This means that valuable time is lost exchanging voicemails. The CS50 effectively reduces phone tag, letting users roam hundreds of feet from their desks and, with the addition of the optional HL10 handset lifter, answer and end calls remotely. In addition, because the CS50 is as intuitive and easy to use as answering the phone, the learning curve is minimal.

“The key to a useful wireless headset product is that it not only needs to be easy to use, but it needs to have the capability to answer and end calls even when you are well out of reach of the phone,” said Rob Enderle, Principal Analyst for the Enderle Group. “Plantronics’ CS50 not only meets that requirement better than any other device, I believe that it has the potential to be the most indispensable new telephony product in the modern executive’s office.”

With the CS50, office professionals gain a powerful set of benefits, including:

• Increased productivity and convenience: Office professionals now have the freedom to carry on conversations up to 300 feet from their office phones using a lightweight, sleek and completely wireless headset.
• Reliable and long-lasting: The CS50 provides up to eight hours of continuous talk time with no worries about dropping calls halfway through the conversation.
• Plug-and-Play: The CS50 works with existing office or PBX phone systems, whether analog, digital, single-line or multi-line.
• Crystal clear and secure communications: Plantronics’ more than 40-year legacy of voice expertise ensures superior sound quality with a noise-canceling microphone that eliminates background sound. To keep conversations secure, the CS50 uses digital 900 MHz transmission to digitally encrypt conversations.

Users also can satisfy their individual style and comfort preferences while gaining additional convenience and functionality with optional accessories. Professionals can customize their CS50 units with a HL10 handset lifter for one-touch call answer/end, a behind-the-head neckband, which provides another style option for personal comfort, and a wall- or desk-mountable in-use indicator that lets others know the user is on a call.

“There’s a huge, unmet need for mobility in the workplace. Out of more than 43 million office professionals, only about 9% currently use headsets,” said Peter Zan, senior product marketing manager at Plantronics. “With the Plantronics CS50, office professionals gain the wireless freedom they need for multitasking, while enjoying increased productivity. The CS50 enables users to move around the office while still communicating effectively.”

System Requirements, Pricing and Availability

The Plantronics CS50 is compatible with standard office phone or PBX systems, and works with analog, digital, single-line or multi-line telephones. Weighing only 26 grams, the CS50 headset comes with three different earloop sizes and an over-the-head band for customizable comfort and style.

The Plantronics CS50 is backed by a one-year warranty and has an MSRP of US$299. The optional HL10 lifter has an MSRP of US$79. The CS50 and HL10 have begun shipping and will be available from U.S. and Canadian distributors and retailers, and at www.plantronics.com.
