Grabbed a pair of these recently and, in brief, they're definitely worth the hype. $150+ sound for $60-80 bucks. Even at $100, these are a really good buy. That's of course with the caveat that you prefer a more neutral and detailed sound. Not everyone likes that sound profile. These are perhaps a touch behind my AD900X (which is an amazing value in itself at $140) in terms of soundstage expanse which makes them sound a bit more natural, but a bit better in terms of clarity. Can't find much to criticize sound wise. Bass is good for me, but again, I prefer it neutral or slightly north of it so not ideal for bass lovers. Mids are very nice and even, though I prefer them a tad more forward. Still very well done and nothing at all to complain about. Highs can be bright in places, but I wouldn't call them offensive or sibilant at all. I like the boost in clarity compared to my AD900X. Both are excellent value, but I'd give the 9500 a nod for being cheaper and on the same playing field. If you like expansive soundstage and naturalness, grab the AD900X. But if you like neutral clarity and detail, the 9500 might be more your bag. Can't decide between them. Very tough call. Not sure I'd say they're as good as 600s, but damn, for the price and how close they get? I love these.
