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.

  • Increased efficiency of 93dB allows the HE400i to be driven with a modest size amplifier or even with a portable audio player or smartphone.

  • 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.

  • ABS polymer ear cups 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 ear pads are made of pleather and velour, which provide both increased comfort and improved sound quality.
