The fully open-back design of this planar headphone eliminates the negative effects of sound wave reflection, an obstacle that impairs sound quality. The model is named UNVEILED because the depth and inherent beauty of the music are unveiled to the listener. The technology is based on the cutting-edge innovation and heritage of HIFIMAN’s flagship headphones, SUSVARA UNVEILED. Since the nanometer-thickness diaphragm is sensitive to reflected sound waves, it is necessary to further increase the openness of the back of the headphones. This was the inspiration for the HE1000 UNVEILED’s removable back panel. The design of the window shade cannot completely avoid reflection and refraction. Only by eliminating the window shade/grill, the design will near lossless sound quality be achieved. Open-Back Planar Magnetic Headphones Stealth Magnet Design. Nanometer Thickness Diaphragm. Grille-Free Unveiled Design. Magnetic Protective Covers. Regular Headphones Commonplace products use mesh with a lower opening ratio as a grill that leads to reflections and refraction that are detrimental to sound quality. Window Shade Design Since the nanometer-thickness diaphragm is very light in weight, it is easily disturbed by sound waves reflected and refracted by the mesh. Therefore, HIFIMAN uses a window shade design to increase the opening rate, maximize the grill exposure and reduce the probability of reflection and refraction. The result: dramatically improved sound quality. Magnetic Veils Specially designed to protect the fully open drivers of the HE1000 UNVEILED. Core Technology – Nanometer Thickness Diaphragm The thickness of the HE1000 UNVEILED diaphragm is under a millionth of a meter. It is extremely light and gives the headphones extremely fast response speed and outstanding dynamic range and frequency characteristics. Combined with the “Stealth Magnets” technology, the nanometer-thickness diaphragm material is essential to the sonic output being clear and non-fatiguing, even after hours of listening. Acoustically Invisible Stealth Magnets The special streamlined cross-sectional shape of the Stealth Magnets optimizes and reduces the air turbulence and diffraction between the magnets, allowing the sound to pass between them almost unaffected, without disrupting the sound quality as is experienced with traditional magnets. Stealth Magnets The special shape of the Stealth Magnets allows the sound to pass through the magnets perfectly without the sound quality degradation of traditional magnets. Degradation of sound Degradation of sound quality in a conventional planar magnetic headphone is caused by the magnets getting in the way of the sound wave. Conventional electrostatic Conventional electrostatic headphones experience degradation of sound quality caused by the stator’s interference. A conventional dynamic driver’s frequency response A conventional dynamic driver’s frequency response can be altered due to distortions and vibrations across the diaphragm surface. Conventional dynamic drivers experience a larger frequency response distortion due to the severe distortions across their diaphragm. The Ear Pads The elegant asymmetry of the HE1000 UNVEILED’s ear pads conform to and fit around the human ear, comfortably distributing the weight evenly yet offering a secure and sound grip. The pads themselves are gently bevelled, contouring and moulding to the user’s head, providing superb comfort for long listening sessions. Cables The cable configuration used for the HE1000 UNVEILED is a single crystalline copper wire alongside a single crystalline silver wire. The highly reliable socket reduces contact resistance to extremely low levels without affecting the transmission of audio signals. The HE1000 UNVEILED package includes three detachable cables: one balanced 3m cable with XLR jack. one single-ended 1.5m cable with 3.5mm jack. one single ended 3m cable with 6.35mm jack.
