HIFIMAN Arya Stealth Magnet Version Full-Size Over-Ear Planar Magnetic Headphone for Audiophiles/Studio

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. HIFIMANs 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.
