Headphone Overview

Outstanding Sound Quality and Spatial Soundstage

Compared to traditional dynamic headphones, the planar magnetic
technology o ers largely superior sounding experience in terms of
quality and soundstage. Dynamic headphones utilize conductors that
vibrate in select areas of the diaphragm. This results in a large percent-
age of the diaphragm that cannot be directly driven by those conduc-
tors. Planar magnetic headphones are fundamentally di erent, and
operate on a di erent technical principle. Firstly, the weight of the
planar headphone (conductors + diaphragm) is much lower than that
of the dynamic headphones. This results in planar headphones' superior
performance in treble. Therefore, the HE400S has a wide range of
frequency response (20Hz-35KHz) to yield spatial expansion.

A smaller mass from either the diaphragm or conductor traces results
in a higher upper frequency bound.
Moreover, 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.

Owner's Guide
This lower distortion results in better overall reproduction of minute
details. Instrumental positioning and imaging are improved, and the
headphone has very natural soundstaging capabilities.

Easily Driven
Benefit from the newest planar driver technology, HE400S
headphones have extraordinary high sensitivity and low impedance
(22 Ohm). In other words, they are one of the simplest to drive planar
magnetic headphones. No longer are you tied to your bulky desktop
amplifier, nor is a portable amplifier necessary to achieve optimal
audio reproduction. You can listen to the music directly from your
smartphone headphone output at reasonable volumes.

Lightweight and Ergonomic Design

The innovative suspension headband and specially designed ear
pads maximize and optimize your listening comfort, allowing you to
enjoy your music for hours on end. Countless hours have been spent
optimizing the design of these peripherals in order to maximize your
listening enjoyment in both audio reproduction and comfort.
