HiFiMAN HE400se Planar Magnetic Headphones – Price & Specifications

The HiFiMAN HE400se is an open-back planar magnetic headphone designed for listeners who want to experience the speed, clarity and low distortion of planar technology at an accessible price.

With its open acoustic design, Stealth Magnet technology and lightweight construction, the HE400se offers an impressive entry point into high-quality headphone listening, combining excellent detail retrieval with a spacious and natural presentation.

Planar Magnetic Driver Technology

Unlike a conventional dynamic headphone, a planar magnetic driver uses conductive traces spread across a large diaphragm.

The diaphragm is driven more evenly by the magnetic field, helping reduce distortion while providing fast transient response, precise imaging and excellent retrieval of musical detail.

This technology gives the HE400se much of the speed and openness normally associated with significantly more expensive planar magnetic headphones.

Stealth Magnet Technology

The current international version incorporates HiFiMAN Stealth Magnets, shaped to reduce interference with the sound waves produced by the planar diaphragm.

By reducing diffraction and turbulence around the magnetic structure, sound waves are able to pass through more freely.

The result is improved transparency, cleaner transient reproduction and a more natural presentation across the audible frequency range.

Open-Back Soundstage and Imaging

The open-back construction allows air to move freely around the planar drivers, reducing the enclosed feeling associated with many closed headphones.

This creates a spacious presentation with clearly defined instrument positioning and convincing depth. The HE400se is particularly attractive for acoustic music, jazz, classical recordings, live performances and gaming where positional information is important.

Comfort for Long Listening Sessions

At approximately 385g, the HE400se remains relatively light for a full-size planar magnetic headphone.

Its redesigned headband distributes pressure across the head, while the beveled hybrid ear pads provide generous contact area around the ears.

The combination makes the headphone comfortable enough for extended listening sessions at a desk or in a dedicated headphone system.

32Ω Impedance and 91dB Sensitivity

The HE400se has a nominal impedance of 32Ω and a sensitivity of 91dB.

It can work with many modern desktop DAC/headphone amplifiers and capable headphone outputs. However, like most planar magnetic headphones, it benefits from an amplifier with sufficient current delivery.

A good dedicated headphone amplifier can improve bass control, dynamic contrast and overall authority, particularly at higher listening levels.

Simple, Practical Construction

The HE400se uses detachable connections and includes a 1.5 metre headphone cable together with a 6.35mm adapter.

Its straightforward construction makes it suitable both as a first serious audiophile headphone and as a second open-back headphone for an established desktop system.
