HiFiMAN's HE400i is a high quality, full sized open-back planar magnetic headphone that has been designed for critical listening and monitoring at home or on the studio. The new generation of the HE400 comes with greatly improved sensitivity and reduction in weight

The HE400i features a single ended thin film planar magnetic driver for a wider soundstage and spatial imaging. It produces clear and more dynamic sound as compared to other conventional headphones.

The HE400i has a striking, contemporary look that doesn't compromise on comfort. The headband has been redesigned, with improved pressure pattern and beveled earpads made of pleather & velour. The soft earpads gently caress your ears, not only improving the sound quality but also making long hours of music listening a total treat. 

This full-sized headphone, features an excellent build quality and an improved design that makes it a perfect pair for every audiophile out there.

  • Efficient Planar Magnetic Headphones

    With a sensitivity of 93dB and an impedance of 35 Ohms, the HE400i can be driven very easily by any modest amplifier of even your smartphones or portable music devices.

    Planar Magnetic Headphones

    Dynamic headphones utilize conductors that vibrate in limited areas of the diaphragm. This leads to a large percentage of the diaphragm not being directly driven by those conductors. Planar headphones have conductive layers over almost all of the diaphragm. Evenly driven by these conductors, the result is significantly lower distortion than conventional dynamic headphones.

    Superb Hi-Fi Quality Sound

    HE-400i deliver high quality sound due to the massive diaphragm that allows high signal input along with flexible bass and treble. The HE400i delivers a lively soundstage and exceptionally immersive spatial imaging. 

    Open Back Design

    The HiFiMAN HE400i has an open design that makes it perfect for home or studio applications. This also makes the HE400i one of the most open, dynamic and immersive sonic experience at this price point.

    Lightweight and Comfortable Design

    The innovative HE400i is 30% lighter in weight than most full size planar magnetic headphones for increased comfort and reduction in fatigue during long hours of music listening. The improved pressure pattern is also designed for exemplary comfort.

    ABS Polymer Ear Cups and Velour+Pleather Ear Pads

    The ABS polymer earcups in a glossy charcoal finish give the HE400i a striking contemporary look. The specially designed beveled ear pads are made of velour and pleather for both improved comfort and sound quality.

    Lightweight Diaphragm Design 

    Due to the lightweight diaphragm, the response time is very fast while the evenly distributed magnetic design allows for low distortion and reproduction of live sound.

  • " The HE-400i is an incredibly good Mid-Fi headphone that you really should look at if you have this kind of budget available. The HE-400i is closer to the HE-560 as the HE-400 was to the HE-500. Another job well done, Hifiman!"

    " The HE400i and the He560 are a step in the right direction for Hifiman and show a much better appreciation of what the market is asking before than previous models in the range. They have taken the best bits of the HE400."

    " Overall, I’m very pleased with the results with the 400i. There is enough sub bass to offer plenty of  a fun factor and enough good natural tone to the mids to be taken seriously with vocally centered music."
