Outstanding Sound Quality

Compared to traditional dynamic headphones, planar magnetic

technology offers a superior sounding experience in terms of the

soundstage and overall sonic output. Dynamic headphones utilize

conductors that vibrate in select areas of the diaphragm, resulting in

a large percentage of the diaphragm not directly driven by the

conductors. Planar magnetic headphones are fundamentally differ-

ent and operate on a different technical principle. Firstly, the weight

of the planar headphones (conductors + diaphragm) is much lower

than dynamic designs. This results in significantly improved treble.

A smaller mass from either the diaphragm or conductor traces results

in a higher upper frequency bound.

Planar headphones have conductive layers distributed throughout the

surface of diaphragm. The diaphragm is evenly driven by the magnetic

force so that planar headphones have significantly lower distortion when

compared with conventional dynamic headphones.

This lower distortion results in better overall reproduction of minute

details. Instrumental positioning and imaging are improved, with a truly

natural soundstage.
