The 5.1 sound is quite frankly, I was quite surprised, it is obviously commercial and can not be compared to a 5.1 speaker system, but still, it holds up. However, I did not appreciate this helmet as he squeezed my head too much, my head do 17.4cm wide if it helps you (measurement taken just above the ear). I also advise you to check each channel, headphone received had my first bass channel was not working right, and I saw on a forum someone who had not left the surround channel is of course supported by the guarantee and replaces the amazon you soon. There also appears to be weak according to some post, but I could not tell. So I have good memories of this global headset apart comfort.
