I'm currently using a headset that is connected to the tv via a jack.
In addition to this connection, there's also a connection for the microphone
Would now like to use this headset to talk via xbox live party
Are there suitable adapter cables for this?
Speak of the normal 3mm blade on the headset connection on the controller
There's the one verified by Microsoft
The latter is no longer sold but unfortunately you can only find it at 50 euro
