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.
