Audio 626 Computer Headset features digital signal processing for enhanced sound quality. The noise-canceling microphone and wide-band 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 24 bit hi-fi stereo 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. Lightweight stereo USB headset also features soft foam ear pads and easy-to-use in-line controls for volume and mic mute.
