HiFi Man HE400SE open-back planar magnetic headphones employ single-ended drivers with increased efficiency to 91dB.

HiFi Man HE400SE open back planar headphones are designed for comfort, durability and performance. They are lightweight, have a full frequency response and use HiFi Man’s Planar technology to increase the audio quality.

What is a Planar headphone?

These Planar headphones have conductive layers that cover nearly the entire diaphragm to significantly lower distortion, unlike regular diaphragms where only a section of it is utilised.

Stealth Magnet

The stealth magnets shape enables waves to pass through with generating interference. Combined with HiFi Man’s advanced magnet design, wave diffraction is reduced, which results in a full-range and accurate output.

Maximised Comfort

The HE400SE headphones have a lightweight headband so that you can wear them for hours and still be comfortable. The outer casing helps better durability against the elements.

Durable Connections

HiFi Man’s HE-400SE comes with a dual sided high-performance 3.5mm cable and a 6.35mm adapter for compatibility with a wider range of products.

  • Frequency Response: 20Hz-20kHz
  • Impedance: 25Ω
  • Sensitivity: 91dB
  • Weight: 390g
