Pros: Very detailed balanced good sound, extremely comfortable. I can wear them for 6 hours at work without knowing they are on, great noise isolation
Cons: some microphonics, had a few pair develop shorts in the wires.
I have some current Senn IE80s and I think the x10s sound better and are far more comfortable IMO. These are underated. I like them enough that I have bought 6 pair due to losing them or wear and tear and I buy the X10i with iphone controls @ $200+ a pop. Thats how much I like them.
