A:Answer I know that the headset can mute your voice over the mic, I have not looked for a way to mute sound to you. The knob on the left earpiece can lower volume to zero, but this is not like a mute button. The boom for the mic does lever up and out of the way.
Overall I'm impressed with this headset. It can be recharging while in use, which was something new to me. The sound quality is wonderful, and the sound dampening from outside sources is good enough that very little gets through. Someone can still call your name and you can hear it, but if you don't like the person you can tune it out and blame it on the headset. I consider this a perfect balance for sound dampening! :)
