Sound level is very good, and especially in games and movies, excellent low to immerse you in the action.
The micro meanwhile is good, although we recognize the voice, there is very little hiss, but it does not have a high degree of insulation, not bad breath due to noise around (adjustable in part as audio chipset ). Moreover the low being pronounced your contacts will also benefit when your volume will be high.
Very good helmet that I do not regret having bought.
