Description
The fully open-back design of the HiFiMAN HE1000 UNVEILED 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 headphone. This was the inspiration for the HE1000 Unveiled.
Window Shade Design
Since the nanometer thickness diaphragm is ultra lightweight, it is easily disturbed by sound waves reflected and refracted by the mesh. Therefore, HIFIMAN uses a window shade design to increase the opening ratio, maximize the grill exposure and reduce the probability of refraction and reflection. The result: dramatically reduced distortion.
Magnetic Veils
Magnetic Veils are specially designed to protect the HE1000 UNVEILED’s drivers. Due to the magnetic properties of the driver, it is important to cover the ear cups with the Magnetic Veils to avoid unnecessary problems or damage caused by the attraction of magnetic objects when the product is not in use.
The Nanometer Grade Diaphragm
Extremely low distortion, extremely high transient response, comprehensive improvement of dynamics and details. For many years, HIFIMAN invested extensive resources into Nanometer Grade diaphragm research and development. This core technology has been further refined in the design of HE1000 UNVEILED. The production, processing and installation of diaphragm materials is highly complex. In addition to achieving a balance of great strength and low mass, it is combined with Stealth Magnets technology to achieve the goal of excellent sound quality. The thickness of the HE1000 UNVEILED’s diaphragm is under a millionth of a meter. It is extremely light, gives the headphone extreme responsiveness with outstanding dynamic range and frequency characteristics. Combined with HIFIMAN’s “Stealth Magnet” technology, the nanometer thickness diaphragm material is essential to the sonic output being clear and non-fatiguing, even after hours of listening.
The Stealth Magnets
The recent innovation in the world of planar magnetic headphones was the development of a new design of magnet that HIFIMAN dubbed Stealth Magnets, in light of them being as acoustically transparent — or invisible — as possible. In traditional designs, the magnets get in the way of the sound waves through reflection and diffraction, creating constructive and destructive interference. As these points shift with frequency changes, there is a mass of wave interference that has a negative impact on the sound. The use of Stealth Magnets in the HE1000 UNVEILED means the sound wave reproduction takes place without the magnets getting in their own way and ruining the sonic purity of the output
The Technology Under the Grill
A conventional dynamic driver’s frequency response can be altered due to distortions and vibrations across the diaphragm surface. 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 headphones experience degradation of sound quality caused by the stator’s interference. Unlike the sound waves created by a conventional magnet, the special shape of stealth magnet of HE1000 UNVEILED enables the waves to pass through the magnets without generating interference.
Cables
The cable configuration used for the HE1000 UNVEILED is a single crystalline copper wire alongside a single crystalline silver wire. A special composition ratio and quantity of the materials ensure low resistance in the signal transmission and high mechanical strength for daily use over many years. The special plug-socket structure makes it easy to swap cable, connecting amplifiers with different components. The highly reliable socket reduces contact resistance to extremely low levels without affecting the transmission of audio signals.
