For volume we can not reduce to the maximum, which is that when you want to mute the sound, one must go through Windows.
That said, it remains a very good headset, microphone quality is very good, we still hear the little noises from the back (Bird, small (e) s sisters and brother etc ...).
I advice to anyone who wants to have these headphones to take if and only if it is for 1 hour, 2 hours of use. Or add a little more for better.
