HiFiMAN HE400se Open-Back Planar Headphones

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.

• 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.

• 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.
