This product replaces the Plantronics .Audio 645 USB Headset.

Digital signal processing provides enhanced sound quality in this comfortable, discreet stereo USB headset. A noise-canceling microphone and wideband acoustic echo cancellation capture a broader range of voice signals for calls that are clearer and more natural sounding. The acoustically tuned equalizer supplies rich, resonant stereo sound and optimizes voice response to clearly hear vocal tracks when listening to music, watching a movie or playing a video game. USB plug-and-play connection means there is no software to install. With a comfortable, lightweight fit and easy-to-use inline controls, the .Audio 646 is the perfect headset for all your PC audio needs.
