HE400i Easy-to-Drive Full-size Planar Magnetic Headphone

Planar Magnetic Headphone
Created by the innovator of the planar magnetic technology, the HIFIMAN HE400i is a high quality, full-size planar magnetic headphone created for critical listening at home or in studio. The new generation headphone becomes more lightweight with largely improved sensitivity.

Planar vs. Electrostatic
Planar magnetic and electrostatic drivers are similar in regards to low distortion and high signal input. Compared to the electrostatic driver, the planar magnetic technology uses a more massive diaphragm that is able to mover very quickly in a coherent and uniform way. The planar magnetic headphone gives excellent transient response and a sound quality almost equal to that of an electrostatic product.

Breakthrough Innovation
Single-ended planar magnetic driver provides superior soundstage and spatial imaging.

The HE400i is 30% lighter than other full-size planar magnetic designs for increased comfort.

Using single-ended drivers, HE400i delivers a lively soundstage and spatial imaging.
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.

The Look
  • ABS polymer earcups in a gloss charcoal finish give the HE400i a striking contemporary look.
  • Improved pressure pattern is designed to provide best-in-class comfort
  • Specially designed beveled earpads are made of pleather and velour, which provide both increased comfort and improved sound quality

High Quality Sound
  • Delivering better quality sound than other headphone types
  • Massive diaphragm allows high signal input and flexible bass and treble
  • Very fast response time due to the lightweight diaphragm design
  • Evenly distributed magnetic force for low distortion and reproduction of live sound
