Pros: Comfort, isolate very well
Cons: Very long cable
Bought as upgrades to me 13 year old Sony MDR-V600s. Can't really assess their audio quality, other than to say they're a clear upgrade from the MDR-V600s.
I bought them for computer use, both gaming and .flacs. Performs very well at both. Can be worn for hours on end. Cuts out ambient noise, and so far my wife hasn't complained about being able to hear them when she's working in the same room.
Tried using them on the bus, but they're not terribly well suited for portable applications. The cable is long and straight, and overall the set is a bit big to be carted around.
Still, very happy with the purchase.
