Absolutely awesome! Stunning set of headphones, I don't need to comment on the quality just check around for other reviews they will make you appreciate just how well regarded they are. Closed back, aluminium housing, lightweight, very comfortable, and incredible sound. Extremely well made, seems like they will never break.
The ear pads are supposedly prone to wear out, much like my other pair of Sony headphones I imagine. Replace with a set of beyerdynamic ones, as they are apparently much better. I can't see mine wearing out for years though! They fold up really well which was a bonus; however the coiled cord could be longer. So I purchased a very high quality Philips headphone extension which means the cord drapes across my desk and does not weigh the headphones down. I really am picking here- they are near as perfect as possible!
I think they also look awesome, not too bulky, a little bit 80's and very stylish. Get them while you can pretty soon there will be none left around to buy!
PS look out for Dr Frasier Crane sporting a pair next time you watch early morning TV ; )
