Summary: I wanted to love these, and I kinda did, but only for classical and jazz. Everything else though was boring to listen to and can sometimes get a bit bright. Also still has that closed sound, but then again it's a closed can. I know I know, it's more for tracking rather than for entertainment.
Pros: Deep, tight fast bass, classic akg mids, clear highs, detailed, comfortable, great soundstage for a closed, retro design, plenty of accesories
Cons: Bass anemic, doesn't play well with bass boosters and/or loud volumes, not very exciting, needs an amp to even get bass at all
Summary: Read a number of reviews on this pair of headphones before buying, and was quite surprised that no one mentioned the boxy band ( maybe somewhere around 3.5 - 5k ?? ) of upper mids.
some songs are pretty effected by it, others not so much.
Pros: Great clarity & sound stage (esp. for closed), great tone on guitar / electric keys, bass is very detailed and punchy
Cons: biggest issue is boxiness in the upper-mids, minor issue - bass is not BOOMing, its mostly the upper bass that you can hear (100+ Hz)
