HiFiMan HE-400i Planar Headphones

The HIFIMAN HE-400i Headphone is a breakthrough in planar magnetic design which provides the most affordable entry point for listeners. This is achieved because HiFiMan have finally figure out a way to mass produce a high end sound quality planar drivers in a much easier way than before. The HIFIMAN HE-400i is a high quality, full size planar magnetic headphone designed for critical listening in the home or studio.

Unlike dynamic drivers used in most headphones and speakers, planar drivers use thin flexible diaphragms with voice coils etched onto their surface rather than a voice coil attached to a cone. This exceptionally lightweight structure uses a large driver surface area to reproduce your music with openness and detail that are difficult to achieve with conventional designs. The HIFIMAN HE400i is 30% lighter than the HE400 that it replaces this allows the listener to be comfortably enjoying there music for hours on end. In addition a newly designed headband and bevelled hybrid ear pads provide added comfort as well as improved sound quality. Also the efficiency of the HE400i has been improved to 93db whilst it allows them to be driven by portable audio devices or smartphone we recommend a modest size amplifier to get the best from the headphones.

A premium cable is included comprising of a Crystalline metal with oxygen free copper and silver as with all HiFiMan headphones they share a symmetrical wiring, where in each driver has it’s own separate audio cable. This results in lower crosstalk between each channel.
