Very good sound, but beware

Having these headphones for over 3 years I confirm the previous comments indicating that the sound is clear. The sound quality is really amazing. A small button to switch from Stereo to 7.1. Soon we no longer use the 7.1, even if the source is stereo, because it feels right immersed on.
I lost count of the games that I can no longer do that through headphones, as the sound to speakers and seems far unclear.

Immersion GA-RAN-TIE!

As said, it's been over 3 years since I have the helmet and I used to do a lot of podcast (2 years of monthly podcast). The microphone is top, excellent qualities and it still works perfectly. The buttons on the edge allow to control the volume and even morph his voice to make jokes. Very fun, even if used only on rare occasions.

Now the least:
The helmet is heavy and begins to become uncomfortable after about two hours of use. If you have a little long hair, the headband will mark your hair;)
Moreover the material on the ears tend to sweat them and with time disintegrates. It's kind of leather, for my part it is being seffriter full of small pieces.
