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. World’s First Diaphragm in Nanometer Thickness: In the HE1000, the film we use is so thin, it is a diaphragm in nanometer thickness which is a breakthrough core technology developed by HIFIMAN and first of its kind in headphone application. Working with this advanced material is extremely challenging yet the successful incorporation of this film as the HE1000’s planar driver is the cornerstone of its remarkable sound.t 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. Advanced Asymmetrical Magnetic Circuit: 7 years of painstaking research with this groundbreaking design offers near perfect reproduction of live music; Patented “Window Shade” System: Created to meet the need for driver protection and optimized open-back design Craftsmanship: 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 craftsmen With its unique design, exceptional function and exquisite craftsmanship, the HE1000 is the total luxury item that redefines the audio landscape. The Plugs: The HE1000 package includes two different types of plugs: ¼” (mini 6.35mm) and 4-pin XLR connector so it can be used with a wide array of equipment. The plugs are easy to switch and quickly connected to different cables and amplifiers.
