Outstanding Sound Quality

Compared to traditional dynamic headphones, planar magnetic
technology offers a superior sounding experience in terms of overall
quality, especially when it comes to the aural soundstage. Dynamic
headphones utilize conductors that vibrate in select areas of the
diaphragm. This results in a large percentage of the diaphragm not
being directly driven by those conductors, resulting in somewhat
diminished performance. Planar magnetic headphones are funda-
mentally different in that their weight (conductors + diaphragm) is
much lower than dynamic headphones. The result is superior perfor-
mance, especially in the upper frequencies, or treble.

A smaller mass from either the diaphragm or conductor results
in improved upper frequency response.

Planar headphones feature conductive layers distributed throughout the
surface of diaphragm. The diaphragm is evenly driven by the magnetic force
so that planar headphones produce significantly lower distortion when
compared with conventional dynamic headphones.
This lower distortion results in better overall reproduction of minute details.
Positioning of instruments and other elements of imaging are demonstrably
better, with a soundstage that is consistently wide and natural sounding.
