HIFIMAN HE400SE Stealth Magnets Version Over-Ear Open-Back Full-Size Planar Magnetic Wired Headphones for Audiophiles/Studio, Great-Sounding, Stereo, Comfortable Fit-Sliver

What is a planar headphone? What are its benefits over other designs? Planar headphones feature conductive layers that cover nearly the entire diaphragm, resulting in significantly lower distortion than conventional dynamic headphones.
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.
