With technology usually associated with much more expensive headphones, the HIFIMAN HE400SE delivers unbeatable value.

Planar technology made better value than ever
Although more expensive to make, planar magnetic headphones offer a number of advantages over conventional dynamic ones. These include lighter diaphragms for a faster response and a linear spread of sound across the speaker, reducing the level of distortion.

Stealth magnets for transparent sound
HIFIMAN’s advanced magnet design enables soundwaves to pass through the magnet, with as little disruption as possible. The acoustically ‘invisible’ magnets let the sound pass through without diffraction turbulence, giving you a purer, more transparent sound.

Easy to drive
A relatively high sensitivity makes the HE400SE easy to power. Although a dedicated headphone amp will always sound best, the HE400SE’s are efficient enough to be driven by most built-in headphone stages or even a portable.

Cool and comfortable
Large earcups envelope your ears for immersive comfort. The wide, lightweight headband evenly distributes weight over your head, making these headphones supremely cool and comfortable to wear for hours on end.

Enjoy the best headphone tech, for less, with the HIFIMAN HE400SE.
