HIFIMAN HE400SE Stealth Magnets Ver.

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.
 
High Sensitivity
The HE400SE’s high sensitivity makes it the perfect match for low-voltage sources. The sound is rich and pure without the need for a bulky amplifier.
 
Maximum Comfort for Hours of Listening Pleasure
Thanks to its newly designed adjustable lightweight headband, the HE400se remains cool and comfortable for hours, even in excessively warm weather.
