Pros: nice mid-treble ratio
Cons: bass rolls off
VERY flat. Now this is a headphone I enjoy.
Except for that bass roll off. Forget the HD800, forget the HD700, find some way to get deep sub bass out of these and you have a winner.
It sounds quite clean and is never veiled (HD650, HD598) nor is ever harsh (HD700, HD800). That is all.
