Our Verdict

The HiFiMAN HE-400s are heavy hitters when listening at home and lend a wonderful weight to any music.

Shaun, Co-founder

HiFiMAN HE-400

Another remarkable achievement from HiFiMAN. Compared to HiFiMAN's top-end power hungry planar magnetic headphones, the HE-400 can be driven with lower-output headphone amplifiers. With low impedance and high efficiency they provide superb sound coupled with great comfort for the best possible portable audio experience.

HiFiMAN's HE-400 creates a soundstage that will make you think you are listening to speakers rather than headphones. With specially designed magnet structures the HE-400 is able to deliver high performance at a price that is hard to beat. The open design of the earcups add to the musical experience with natural and unfastened dynamics.

The earcups of the HE-400 are lightweight, which means that you can enjoy these headphones in great comfort during long listening sessions. With full sized earcups that rotate in two axes the HE-400 conform to the head shape and sit securely. Special soft earpads make the comfort factor complete.

A new level of performance: HiFiMAN HE-400.
