surround sound headphones for xbox?

I'm looking for some recommendations on a good pair of surround sound headphones for xbox 360.

I've looked at the turtle beach x1's and x3's but neither have surround sound. I also looked at the ax360's by trittion and these seem to be the best bet so far, though I've read good and bad about them. I'm hoping someone can either recommend a different pair or let me know how the ax360 fair on xbox live.
