A favorite of office workers and IT professionals — the Voyager 4200 UC Series. Some office workers prefer a stereo headset to listen to media and music. Others prefer a single-ear headset so they can hear what's going on around them while on a call. But everyone expects the same from a headset: crystal clear sound and the ability to switch seamlessly between a mobile phone and a PC. The Voyager 4200 UC Series is easy to use, easy to deploy and manage, and cost effective.
