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. NEO supernano Diaphragm (NsD)- Hear what you have been missing: The all new NsD is 80% thinner than previous designs resulting in a faster more detailed response while retaining lush musicality never before possible. At between 1 to 2 microns thick, the NsD diaphragm sets all be standards. High Sensitivity: High Sensitivity allows use with virtually any smartphone or portable audio device. Low distortion and amazing sound quality. Window Shade Grill Design greatly reduces sonic reflections for clearer sound; Asymmetrical Ear
