Not to be bought!
Very bad helmet!
First of all, the sound is just bad. You can hear very little, badly and not in the right place (in game for example where you have to know where the enemy is).
Secondly, the microphone is really bad too. Sensitivity too low even with amplifier. My team mates have the impression to hear me "from far" and very softly.
Finally, this headset is way too big, it looks like a pilot's helmet.
In short, not to be bought!
I would like to add that the delivery was very fast and that LDLC's customer service was understanding and refunded me after returning the item.
So I am very satisfied with LDLC services. Too bad this headset is just bad...
