Headset adaptor replacement cable

When I bought my adapter a cable was included. You should be OK just ordering the adaptor. The adaptor in the UK should be the same as the USA I would think. The answer to your other question is your headset is a xbox 360 headset so without the adaptor your
sound quality would be poor and your friends might complain about your mic quality. You can buy the cable without the adaptor and if you have any issues then just order the adaptor.

The audio adapter plugs into the large AV socket above the HDMI socket on the back of the console. The green-red/white audio cable that came with the headset then connects the headset to the adapter.

This then gives a direct audio signal from the console to the headset.

If you are the owner of an original Xbox 360 (large) and have purchased a headset that connects to the console via an optical cable, you will need to purchase the HDAV Adaptor(unless already supplied with your console at purchase). The HDAV Adaptor connects
to the rear of the console and gives you the optical port not included on the console. (The slim Xbox 360 has an optical port as standard)

If using HDMI to connect to the TV you will need to purchase the HDAV Adaptor to use the headset. The AV port on the console is very close to the HDMI port, this means that when a HDMI lead is connected to the console the standard AV lead will not fit.

The HDAV Adaptor has been made to allow both itself and the HDMI cable to be connected at

the same time.

If your headset is a stereo headset (not connected via optical) and your TV does not have Red and White stereo audio phone's out. The HDAV adaptor is equipped with Red & White stereo audio out phones as well as an optical port so your stereo headset connects
here.

It should also be noted that if a HDMI cable is not being used, i.e. a Component cable or composite cable is used, then wired headsets can piggy back with those connections so the HDAV adaptor is not needed.

Change the cable round going from the adaptor to the headset.

Try again, take out the adaptor and put it back in

try again, turn off the headset

try again

If none of that works, you need to find out if the issue is the adapter, the cable, or the headset.

(you can't even test them on the 360 to find out if the mics working)

Sorry I can't help more.

It is, you'll get a usb cable with the chat adaptor/stereo headset which is what the firmware update is for

The adaptor is for the chat cable portion of any headset wired or not. My TB X31's connect via USB to the console. That is the RF signal box part which will be for game sound. The adaptor then converts the chat cable to the new controller port for chat only.
