Loading the model

HIFIMAN's planar flagship, with a diaphragm under one micron thick and magnets shaped so sound passes them with less diffraction. At 83 dB sensitivity it needs a powerful amplifier, and HIFIMAN says so in its own literature.

Engineering notes

  • Stealth Magnets: magnet structure shaped so sound waves pass through with less reflection and diffraction
  • Nanometer Grade diaphragm under one millionth of a meter thick, with gold conductor coating carried over from the HE6
  • Patented Window Shade outer grille designed to control secondary reflections toward the diaphragm
  • Low-sensitivity design (83 dB); HIFIMAN recommends a high-power amplifier (EF1000 at launch)

Design language

Classic hi-fi proportions: a hand-polished metal arch, wood veneer on the cups, a calfskin strap and the brushed Window Shade grille.
