Excerpt: I purchased a set of these for my home studio after using them in a variety of settings in the studio where I work. As others have mentioned, the bass response can be a bit deceiving. But I wouldn't recommend mixing with headphones alone anyhow.
Excerpt: Mine are still made in Austria, too bad the new ones are made in China. But nonetheless... These are excellent tracking headphones. Not very useful for casual listening, though they sound great, but not nearly as comfortable for any lengthy listening like an open back can would be.
Pros: Easy To Use, Excellent Sound, Low Distortion, Powerful
Excerpt: I use the K271 headphones for mixing my audio projects. The sound is great! They are pretty comfortable, though I have to take them off periodically to give my ears a break. Over long periods of time they start to be of slight discomfort, but that can be said about any headphones.
Pros: Clear Sound, Easy To Use, Lightweight, Versatile
Summary: Comfortable and accurate. I've tracked all day with these, and been the better off for it. I have yet to find anything I don't like about these headphones. My other pair of older K240M's seldom get used anymore, though due to the semi-open back of those, they are still more useful for general...
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
