I'd a pair of the X31's but they were left out and my 2 year old son spilled orange juice on them. 
I liked them, but I found the sporadic interference kinda annoying so I think I'm gonna go for the wired ones next, the DX11's, as their replacement.

Any one have any experience of them? They any good?
