The AKG K 701 Studio Reference is one of AKG's, or Akustische und Kino-Geräte's many succesfull headphones. This model in particular, is a full size studio headphone, with an open ended design. These headphones, aside from their physical appeal in design and comfort, have clean and flat sound that is appreciated by most listeners.
The overal tonality of the headphone, besides its noted detail and depth, is flat and balanced. A flat frequency response is great for the average audiophile, but for the more average consumer, a little boring. They are also notoriously difficult to drive, and are very detailed. The sound is slightly warm, compared to the average headphone as well.
