Summary: So I'm not going to try to impress you with my resume or be unnecessarily verbose here...
I'm having a little trouble justifying the purchase of these cans after a few hours of playtime - I'm not a staunch believer of burning in, but I'll give it a shot and amend if there is a change.
Summary: After burn-in and listening to them for a hundred hours or so, plus live mix time this is my perspective on their audio.
Coming from Sennheiser HD280 Pros and Shure SE215s, these seem to be amazingly balanced.
Pros: Weighty, firm clamp, massive earcups. Shure sound, replaceable one-sided cable, great build quality. So cheap.
Summary: For less than $200 you won't find a better pair of headphones for studio use. I wouldn't recommend these to anyone who isn't going to be using them in a studio. You can't really take them with you and there's much more "fun" hi-fi headphones for home use.
Pros: Very flat sound across the board, reliable for checking mixes, build quality is there.
