Digital signal processing provides enhanced sound quality in this comfortable, discreet stereo USB headset. A noise-cancelling 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 equaliser supplies rich, resonant stereo sound and optimises voice response to hear vocal tracks clearly when listening to music, watching a film 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 DSP is the perfect headset for all your PC audio needs.
