Product Information

The HiFiMAN HE-400i is a high quality, full-size planar magnetic headphone designed for critical listening in the home or studio. 

At little more than twelve ounces, HE-400i is 30% lighter than comparable planar magnetic headphones allowing the listener to comfortably enjoy music for hours on end. In addition, a newly-designed headband and beveled hybrid ear pads provide added comfort as well as improved sound quality.

Using single-ended drivers, HE-400i delivers a lifelike soundstage and spatial imaging. Its increased efficiency of 93dB allows it to be driven with a modest size amplifier or can even be used with a portable audio player or smartphone.

A premium cable is included comprised of Crystalline metal with Oxygen-free copper and silver.  

HE-400i features ABS polymer ear cups in a gloss charcoal finish.
