Thanks!
Now, I looked at the pictures and read the article and I am still trying figure out why the headphones have a wire connected to the game controller... The pic with the kid wearing them shows the cord, however the layout on the 2nd page (details) doesn't show a wire but kind of hints at one in the diagram. Unless the wire is for YOUR voice to get back to the Xbox.
The look interesting, but i'm not ready for a hundred bucks outlay.. I purchased a pair of surround sound 900mhz wireless headphones from Acoustic Research for 49.95... They connect via digital coaxial, TOS link fiber, or even rca audio, depending on your setup. They are great.
