HIFIMAN HE400SE Over Ear Full-Size Planar Magnetic Headphone

Features:

• Easy to Drive: One of the highest efficiency planar phones in the world! HIFIMAN’s newest HE400SE V2 sounds terrific on your smartphone or most any portable audio device.
• Superb Hi-Fi Quality: HE400SE V2 delivers all the lifelike clarity, detail, extended bass and wide sound stage that audiophiles have come to expect from HIFIMAN.
• Advanced Magnet Design: 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.
• Planar Headphones: Planar headphones have conductive layers over almost all of the diaphragm. Evenly driven by these conductors, result is significantly lower distortion than conventional dynamic headphones.
