That means deep, clean bass with remarkable power and unmatched sound quality. What else would you expect from the people who introduced the world to private listening?

Not only do these professional headphones provide extremely low distortion, they also offer unbeatable sound quality and reproduction for an utterly unique listening experience.

Included with the ESP/950 is the leather carrying case for easy storage and portability.
