Works perfectly well! Its not great but still good, I play with a helmet and 7.1 can be felt! Only downside: you have to press hard on the "volume down" button so that it works but I do serves me absolutely contrary to the button to mute the microphone works it perfectly! I suggest a mini USB extension cable (5 cm) to prevent breaking, welds are not bad, they just can not be better! With an extension cord if you pull the card is removed and follow the movement without breaking!
