Description
  • What is a planar headphone? What are its benefits over other designs? Planar headphones feature conductive layers that cover nearly the entire diaphragm, resulting in significantly lower distortion than conventional dynamic headphones.
  • 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.
  • Durable Connections The headphone’s drivers are protected by a newly designed casing for enhanced durability and protection from the elements. 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 HE400SE’s high sensitivity makes it the perfect match for low-voltage sources, including portable hi-res. audio players.
  • 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.

FAQs

Does the HE400se support Bluetooth?

No. These are wired headphones and connect using an audio cable.

Do I need a headphone amplifier?

A bulky amplifier is not essential. However, available volume depends on your source. If your device cannot provide sufficient output, consider a compatible headphone amplifier.

How do I connect it to my devices?

Use the supplied 3.5mm cable or included 6.35mm adapter with a compatible headphone output. Devices without a headphone jack need a suitable audio adapter or DAC.

What makes planar magnetic headphones different?

Their diaphragm uses a broadly distributed conductive layer, helping reduce distortion and reproduce fine musical details.

What is Stealth Magnets technology?

The specially shaped magnets help reduce interference with sound waves passing through the driver.

Is the HE400se comfortable for longer listening?

Its adjustable padded headband is designed for extended listening. Comfort will vary with head size and personal preference.
