Hifiman HE1000 Stealth planar magnetic over ear, open back headphone, is a model that debuted in 2021 at more than twice its current price. It remains an incredible high end headphone with a balanced sound, outstanding detail, comfort and build quality - and now more than ever, a terrific value not to be overlooked at this deeply reduced price.
 
CNC Milled Metal Components 
HE1000 Stealth has CNC milled and hand polished components in the headband, earcups and arms, providing a beautifully finished headphone with excellent structure. The wide leather, perforated headband with low clamping force has no pressure points on the top of the head, well suited to long listening sessions.
HE1000 Stealth polished hand finish is gorgeous, with solid metal reinforced 3.5mm connectors, for reliable, long life operation.
 
Stealth Magnet Technology
The advanced magnet design used on the HE1000 Stealth aims to be as acoustically transparent, or invisible as possible. In traditional designs the magnets' physical presence creates their own impact on the sound waves from the diaphragm, by reflection and diffraction. Hifiman engineered a way to substantially reduce the acoustic effects from these magnets, substantially improving the audio quality.
This system allows the drivers and magnets to better function and you can hear the pure, clean detail and layers in the music that the HE1000 Stealth is known for.
 
Ultra Thin Nanometer Diaphragm 
HE1000 Stealth uses an ultra thin Nanometer Thickness diaphragm for remarkable speed and response. Soundstage is enhanced and distortion reduced by the curved surface Stealth magnets and Asymmetrical Magnet design, with larger magnets on the rear of the driver and smaller, thinner magnets in front of the driver. 
Combined with the Window Shade Grille, HE1000 Stealth provide outstanding imaging and soundstage properties. The Patented Window Shade grille further reduces reflections while protecting the drivers, improving audio quality.
