The HD500 allows you to easily switch the headset to fit either ear. Binaural headsets can be worn with the microphone on either side.
The noise-canceling, boom-style mic delivers crisp, clear sound to the person you are talking to by cutting down on background noise and clarifying your voice. For best results, position your microphone approximately 1/4 of an inch away from the edge of your mouth.
