Deva Pro Open Back and Over Ear

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.

HIFIMAN Heritage: HIFIMAN’s NEO "supernano" Diaphragm (NsD)- The new NsD is 80% thinner than previous designs, resulting in fast response and detailed image with lush, full range sonics.
