Called up the Microsoft Store this morning. Was on hold for only 3 minutes. Got the order in quick and painless.
Had it ordered from amazon, then digital river, now here.

Not a bad price for the quality headphones.
Used the search, didn't see this posted anywhere.
I've gotten a couple from microcenter that work well with the 360. If you have one nearby its a good deal at only $5, but if not shipping is $5.99 putting it a little high.

I just got the pair he listed at the top for only 10 dollars at my Walgreens. They are horrible, couldnt get them to work with anything except the radio feature and my mp3 player if I sat the right way.
