Press Release Plantronics Introduces Award‐Winning Voyager PRO UC Headset with Sensors for Smarter Voice Presence PLANTRONICS ENABLES SIMPLY SMARTER COMMUNICATIONS FOR MOBILE PROFESSIONALS th Mobile World Congress, Barcelona, Spain – 14 February 2011 – Plantronics, Inc. (NYSE: PLT) today introduces the award‐winning Voyager™ PRO UC Bluetooth® headset. It simplifies communications for mobile professionals by unifying voice presence across multiple smartphones and PC–based softphones. The intelligent smart sensor technology makes it the first headset to intuitively know when it is on your ear and when it is not. Incoming calls can be answered by simply putting the SmartSet on (dON). Taking the SmartSet off (dOff) routes the call back to the phone or, when not in use, automatically locks the call button to prevent accidental dialling. “The business world has evolved. Teams are more dispersed ‐ working anywhere and at all times of the day. This evolution demands a new set of communication tools, platforms and devices to simplify communication” said Stuart Bradshaw, Plantronics EMEA Head of User Segment Marketing “Mobile professionals need to be able to deliver the same level of service and high quality of work as those in an office, no matter the time or location. Plantronics offers a complete solution including the right products, software, skills and support to enable professionals to simply communicate.” SIMPLY SMARTER COMMUNICATIONS™ SMART PRESENCE Plantronics’ intelligent Voyager PRO UC SmartSet makes it easier for mobile professionals to unify voice communications across softphone clients such as Skype® and Microsoft® Lync™ with their smartphones. Currently, online voice presence can be confusing and ambiguous with inconsistent and complex status setting choices. The Voyager PRO UC SmartSet simplifies this by automatically updating the user’s presence – depending on whether the headset is being worn or not ‐ across all soft and mobile phones. Displaying an accurate status and knowing exactly when your colleagues or customers are available and willing to engage, makes for an easier and smarter way of working. SIMPLY SMARTER COMMUNICATIONS™ SMART SENSOR Making and receiving calls is made simpler with the new Smart Sensor technology in the headset. Users can answer incoming calls simply by putting the headset on their ear – no buttons to press, applications to open or voice commands required. It will also cleverly route calls to the headset if you’re wearing it and to the handset if you’re not and has a locking call button when it is not worn to eliminate accidental calling. It also has enhanced voice alerts announce remaining talk time, connection status, battery‐ level and mute. 4/7/11 Plantronics Introduces Award‐winning Voyager PRO UC Headset with Sensors for Smarter Voice Presence 2 SIMPLY SMARTER COMMUNICATIONS™ SMART SPEECH Without face‐to‐face interaction, it is even more important for mobile professionals to make an impact with their voice. When conducting business over the phone, body language is replaced by tone of voice, which accounts for 87% of communication, with the actual words and content used only accounting for a mere 13% of total effectiveness. Therefore tone of voice, together with pace, pause, power and pitch can affect end results and by tuning these, professionals can be more influential and effective during phone conversations. Plantronics’ ‘Speech Impact Academy’ ensures that users maximise the potential of their voices to clearly get their message across. INDUSTRY LEADING AUDIO QUALITY The Plantronics Voyager PRO UC headset delivers world‐class noise‐cancellation with 2 AudioIQ , its award‐winning digital signal processing technology, and is enhanced by a ® unique adjustable dual‐microphone boom. The SmartSet has three layers of WindSmart technology to minimize wind distortion and delivers unmatched inbound audio quality to ensure every word is heard on both sides of a conversation. BROAD COMPATIBILITY Plantronics Voyager PRO UC offers compatibility with leading communication clients from Avaya®, Cisco®, IBM® and Skype® and is available in a version Optimized for Microsoft Lync and Office Communicator. PRICING AND AVAILABILITY The Plantronics Voyager PRO UC, including the new mini‐USB Bluetooth adapter for maximum portability and software that enables interaction between the PC and mobile phone has an MSRP of £119 / €149 ex.
