Why choose a dynamic headphone when you can have planar?
Dynamic headphones utilize conductors that vibrate in limited areas of the diaphragm. Result is that a large percentage of the diaphragm cannot be directly driven by those conductors.
Planar headphones have conductive layers over almost all of the diaphragm. Evenly driven by these conductors, result is significantly lower distortion than conventional dynamic headphones.
User Replaceable Connector Design
The plugs are easy to switch and connected to different cables and amplifiers. With an additional purchase of a 4-pin XLR connector it is possible to enjoy fully balanced driver experience.
Cable
The HE400S cable utilizes finely stranded single crystalline silver plated copper wire for improved conductivity.
The braided design and dielectric insulation help resist interference without being overly bulky.
The outer sheath achieves a flexible and tangle-free physical design ideal for portable audio applications.
The new 2.5mm TRS plugs allow for ease of insertion and removal of the cable.
