Headset set up

Yes, it is true that you will need that adapter for use with an HDMI cable. I'm not sure about the fit on a slim, but you could consider this

Actually, what I did was use HDMI to my HDTV for video, and use the a/v cable the came with the 360 for audio. I'm not sure if the adapter that's sold amazon has it, but the tab I mentioned is actually on the a/v cable that came with the console.

So if you have the a/v cables, you won't need an adapter! Just cut off the tab that's on the a/v cable. I now have the HDMI going to my TV, and the a/v(red/white) cable going to my Logitech F540.

There's a tab on the adapter that will block the HDMI port. What I did was just cut off the tab, and both HDMI cable and adapter will fit.

Hello Wayne,

Thank you for posting here on the Xbox forums. This link here has steps on setting up official Xbox stereo headsets but, it should still be relevant with the headset you purchased as well :

Hope this helps!

Sounds like you need a male-to-male RCA audio cable to put hook your headsets cables to your TV's "audio out" inputs (assuming you have them)....
