Hifiman HE400se Entry-Level Planar Magnetic Over-Ear Headphones | Headphones.com

Headphones.com is happy to bring you the global version of the Hifiman HE400se Over-Ear Planar Magnetic Headphones which features Hifiman's unique stealth magnet design. The stealth magnet design is unique to the global version and is not including in the version available in China. The stealth magnet helps reduce wave diffraction turbulence and reduces distortion levels to barely audible levels.

Acoustically Invisible Stealth Magnet

Unlike the sound waves created by a conventional magnet, the special shape of Hifiman's stealth magnet enables sound waves to pass through the magnet without any interference.

Hifiman's advanced magnet design is acoustically transparent, reducing wave diffraction turbulence which would lead to a degradation of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range.

Maximum Comfort for Your Listening Pleasure

Thanks to the Hifiman HE400se's newly designed adjustable, lightweight headband, the HE400se remains cool and comfortable for hours, even in the most extreme heat.

The Hifiman HE400se planar magnetic headphones also come equipped with a newly designed driver casing for enhanced durability and protection from the elements.

Durable Connectors

The Hifiman HE400se ships with Hifiman's dual 3.5mm headphone side connectors and single-ended 3.5mm on the amp side with a 1/4" adapter. If there was any flaw with the HE400se, it would definitely be with the cable which we would recommend replacing when you have the chance. As the HE400se uses 3.5mm connectors, there are countless aftermarket cables that will do the job.
