The headphones are noted to be very revealing and honest with their sound signature. This means bad recordings will sound bad and good recordings will sound good. This is essential for any critical listening and mix decision making. Isolation was said by several users to be excellent, offering very minimal sound leakage. Mixes done on the headphones are said to translate well to other listening devices.
Some users found that the revealing and critical nature of the headphones too unforgiving. This is the same problem some people have with Yamaha NS-10m Studio monitor with it's revealing midrange. Several found the headphones to be uncomfortable.
The MDR-7520 is a serious piece of kit for more discerning ears that don't care for exciting bass or flattering midrange. For critical listening and mixing, the sound signature of the MDR-7520 does well with presenting you an accurate representation of your mix. If you prefer hi-fi sounding references, you may be better off with a different pair.
