Pros: Perfect comfort, very good separation, airy sound.
Cons: Out of control bass, somewhat flimsy construction
I've had these almost two years ago for a few months and enjoyed them quite a bit, but just couldn't get over the problems that had (besides being open and offering no isolation at all; my mistake here). The sound is good, good detail, smooth highs, without much sparkle, but the mids were too weak for my liking and the bass.. well, it was a big disapointment. Maybe if amped properly they'd sound better, I don't know nor do I care much, given that these are supposed to be easy to drive compact portable cans, not on the same level as real mid-fi or hi-fi cans. The bass was just flabby and boomy, not what you'd expect from nice open cans like these. Too bad, because they did a few things right soundwise (lovely instrument layering comes to mind) and were the most comfortable things I've ever put on my ears: light and with no clamping force.
I'm almost tempted to buy these again and try them with my new sources..
