  • Delivers a balanced 93dB of sound

  • Ortho dynamic (aka planar magnetic) drivers

  • Extremely comfortable oversized design

The sound is more open and clearer than ever before. Some experienced audiophiles may think these two new HiFiMans' sound is close to what you might get from the better electrostatic headphones, and that level of sonic purity is unprecedented in the HE-400i's $499 price class," Steve Guttenburg, CNET, January 2014.

HIFIMAN HE-400i is a full-size planar magnetic headphone intended for high performance listening in the home or studio. The HE-400i is 30% lighter than comparable headphones allowing the listener to comfortably enjoy music for hours on end with minimal listener fatigue. 

Along with the lighter weight, a newly-designed headband with an improved pressure pattern is a key to the phone’s best-in-class comfort. The FocusPad, new beveled hybrid ear pads made of pleather and velour, provide both increased comfort and improved sound quality.

The gloss ear cups are finished in a smoky gray, Mylar finish that gives the HE-400i a striking contemporary look.
