Request A Price Match

The HIFIMAN HE1000se is an open back planar magnetic headphone. It features a nanometer-thick diaphragm, asymmetrical ear cups, and acoustically invisible magnets for exceptional detail retrieval and all-day comfort. Joshua Valour calls it “the most detailed headphone” he’s ever heard. 

Nanometer Diaphragm

When it comes to detail retrieval, no factor is more important than the diaphragm. Required to oscillate up to 20,000 times a second, most diaphragms, which are made of plastic or cardboard, can’t overcome the hurdle of their own inertia to reproduce lifelike detail. The HE1000se, on the other hand, features a diaphragm that’s less than a millionth of a meter thick. This exceptional thinness allows it to reproduce unparalleled details and lifelike imaging that you won’t find on other headphones. 

All-Day Comfort

The ear cups of the HE1000se are asymmetrical, following the natural shape of the human ear for a natural fit you can enjoy for marathon listening sessions. 

Protection Meets Purity

The HE1000se features a “window shade” grill that both protects the driver with its sturdy metallic material and allows ample space for sound waves to escape, resulting in both durability and sonic purity. 

Acoustically Invisible Stealth Magnets

While many open back headphones prevent sound waves from escaping with poorly designed drivers, the HE1000se utilizes a specially-shaped magnet which allows waves to pass through without generating interference. The result is a massive reduction in wave diffraction turbulence and far less distortion.
