About HIFIMAN

Founded by Dr. Fang Bian in 2007, HIFIMAN is widely regarded as one of the leading manufacturers of high-performance headphones and portable audio products. HIFIMAN is especially known for its critically-acclaimed Planar-Magnetic headphones that feature state-of-the-art driver technology. The company also designs and manufactures world-class dynamic in-ear drivers which have also garnered awards and rave reviews

Acoustically Invisible Stealth Magnet

Unlike the sound waves created by a conventional magnet, the special shape of Stealth Magnets enables the waves to pass through the magnets without generating interference.

HIFIMAN’s advanced magnet design is acoustically transparent, dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range.

Frequency Response: 20Hz-20kHz Impedance: 32Ohms Sensitivity: 91dB Weight: 385g

What is a planar headphone? What are its benefits over other designs?

Dynamic headphones utilize conductors that vibrate in limited areas of the diaphragm so that a large portion of the diaphragm is not driven to its full capacity. Planar headphones, on the other hand, feature conductive layers that cover nearly the entire diaphragm, resulting in significantly lower distortion than conventional dynamic headphones.

Form follows Function

High Sensitivity

The HE400SE’s high sensitivity makes it the perfect match for low-voltage sources. The sound is rich and pure without the need for a bulky amplifier.

Maximum Comfort for Hours of Listening Pleasure

Thanks to its newly designed adjustable lightweight headband, the HE400se remains cool and comfortable for hours, even in excessively warm weather.

Durable Connections

A dual-sided high-performance 3.5mm cable is packaged with a 6.35mm adapter for maximum compatibility with a wide range of devices.

The headphone’s drivers are protected by a newly designed casing for enhanced durability and protection from the elements.
