Lightweight Design: These headphones are lightweight for comfort during extended periods of use.
Acoustic Turbo Circuit: A special circuit in the headphones provides high efficiency and extended bass response; this helps the headphones produce high quality sound that is powerful and clear.
30mm Drive Units: The drive units are larger than those found in most headphones; the result is deeper bass response, lower distortion and wider dynamic range.
PET Diaphragms: Each drive unit is made with a PET diaphragm; the low mass and high rigidity of PET keeps distortion to a minimum, and it allows for high frequency response that extends to 20,000 Hz.
