You Are going to need a Ear Force Xbox 360 Audio Adapter Cable what this does is it connects to the A/V port on the back of an Xbox 360, and provides red and white (stereo) outputs, as well as a digital optical (S/PDIF) output. The adapter is necessary because the Xbox 360 does not allow both the HDMI and A/V cables to be plugged in at the same time.
Do you need the Xbox 360 Audio Adapter?
- Stereo headsets require it if you're using an HDMI cable to connect your Xbox 360 to your TV, and if your TV does NOT have white and red AUDIO OUTPUT jacks.
- If you have a newer Xbox 360 E (released June 2013), click here. The Xbox 360 Audio Adapter is not compatible with the Xbox 360 E, but you will not need any additional cables anyway.
If your Xbox 360 and TV are connected via HDMI, the headset's RCA splitter cable (included) will need to be connected to 'AUDIO OUT' jacks on the back of your TV
