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)
Summary: When visiting recording studios in Europe or looking at the sales ranking of Germany's largest online store for musicians, the AKG 271 appears as the most popular studio headphone, well ahead of any competition.
Pros: neutral, comfortable, closed, cheaply replaceable cables and earpads
