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. Nanometer Thickness Diaphragm A breakthrough core technology developed by HiFiMAN, it’s the first of its kind in headphone applications. Working with this advanced material is extremely challenging, but the successful incorporation of this film as the Arya’s planar driver is the cornerstone of its remarkable sound. Craftsmanship and Comfort The metal structure is created via CNC milling and hand-polishing. To meet the critical standard set out by HiFiMAN, the surface finishing is handled and refined by meticulous craftsmanship. The ergonomic headband design is comfortable for most people, with greater reliability and durability. And the asymmetrical earcups follow the natural shape of the human ear for increased comfort and decreased fatigue. Sturdy 3.5mm Connectors As with all HiFiMAN products, the Arya features 3.5mm headphone connectors that are angled at 10°, thereby lessening the pressure points associated with straight-angled connectors. These pressure points sometimes stress the connection, but the angled design ensures a solid, reliable and long-lasting link between the headphone and the cable. Furthermore, the user-replaceable connector design allows easy cable swapping, giving both maximum durability and enhanced customizability.
