The listing, Negotiator universal gaming adapter for Xbox 360 and ps3 only has ended.
Here is a ONCE used gaming audio adapter. I tried it on my ps3, worked great, then got a 360 with turtle beach x41 so it's been sitting around. Basically, it works with xbox 360 or ps3. I can't find the adapter to hook up a pair of headphones to a pc. You CAN GET ONE Cheap On EBay OR walmart. Instructions included with NOX website, should u needed help. Pics show how to hook up. It has a 12' cable to reach across room to gaming system. It has an optical audio digital that u plug into back of system, then u out plug the dingle into front usb port for power. It just gives it an excellent digital audio sound, if your headset is basic sound. Any questions please feel free to ask. Thanks!
