Things You'll Need
Instructions
Place your PC headset on a flat working surface. You will be working with several small adapters, so working on a well-lit surface will make losing your adapters much less likely.
Insert each female 3.5mm plug into a 3.5mm to AV adapter. The plugs should click into place and rest flush against the adapters without any gaps.
Insert the male ends of both AV adapters into the AV to 3.5mm adapter. These plugs won&'t click, instead sliding into place with moderate force. Ensure that there are no gaps between your adapters before moving forward.
Insert the 3.5mm plug into the 2.5mm adapter. As in Step 2, the plug should click into place.
Insert the 2.5mm plug into the base of your Xbox 360 controller. In essence, you converted the stereo 3.5mm plugs from your PC headset into a single 2.5mm plug.
Put on your headset and turn on your Xbox 360. Select a random friend from your Friends List and create a voice test message. Do not send the message--play it back by pressing the "Play" button. If you hear your voice in the headset, you&'ve been successful. Delete the message to avoid sending it to your oblivious friend.
