this is what i did to get mine working, i posted this in another thread. it worked but it wasnt an ideal solution, thats why i took mine back and got a refund, at the end of the day, if your just a gamer, then these gaming headsets are okay i suppose, but if you enjoy your music too, then all gaming headsets are rubbish tbh, i went back to my AKG K550 headphones with a seperate mic, far superior to any gaming headset.

"well ive sort of fixed mine, cover one side of the mic with blutac, dont run the dolby, xear surround, enviromental effects or anything else. then go on teamspeak or whatever you use and play some music and keep moving the volume up until you start to get feedback, then just reduce it until you dont. thats the only way ive managed to get mine to work, also make sure you have no mic boost, this has worked for the last couple of days, until monday when i take them back for a refund. **** support on this forum tbh, i know its been around xmas time but jeez, way to sell your products meh".
