I was going to buy those or the Tritton AX720's but I already have a sick set of headphones (~$200) and it would just be insane to buy such an expensive pair for XBox only...

I've owned these babies for about 4 years and the pricing is still about the same as when I bought them. That's craziness in and of itself.
I guess that's really the only option though. Maybe I can play with some of the filter settings on my receiver.
