Here is another thread on the subject.

It's probably the cheapest method to add Sennheiser to Xbox. It is stereo only unfortunately but it is sub $100 on amazon now. Of course, I'm loving my Sennheiser and Mixamp combo, downside is it cost me almost $300.

I'm using the Sennheiser HD599 headphones.

Cool! Thanks for the heads-up OP. I didn't know Sennheiser ventured into the xbox world-Sennheiser X 320, this is good news. I'm going to have to keep an eye on them for future console products.

Turtle Beach's have the worst audio quality. The Trittons aren't much better, really. The thing to do is get an Astro Mixamp, then get some nice headphones from Sennheiser or Audio-Technica. I use the Sennheiser PC360's and they're excellent.
