What is a planar headphone? What are its advantages over other designs? Planar headphones feature conductive layers covering nearly the entire diaphragm, resulting in significantly lower distortion than conventional dynamic headphones.
Acoustically Invisible Stealth Magnet: Unlike sound waves from a conventional magnet, the special shape of Stealth Magnets allows the waves to pass through without generating interference. The sophisticated magnet design is acoustically transparent, greatly reducing wave diffraction turbulence that compromises sound wave integrity. The minimized distortion delivers a pure sonic output that is accurate and full-range.
Robust Connections: The headphones drivers are housed in a newly designed casing for improved durability and protection. A dual-sided high-performance 3.5 mm cable is included with a 6.35 mm adapter for broad compatibility with a wide range of devices. The high sensitivity makes it an ideal match for low-voltage sources, including portable hi-res audio players. Maximum Comfort for
Extended Listening: Featuring a newly designed adjustable lightweight headband, the headphone stays cool and comfortable for hours, even in excessively warm weather
