The new HiFiMAN HE-400SE

The reborn of the original HE400i with the launch of HE400i 2020 version last year has been a great success and we are looking forward to improving this already famous headphone. Here comes the HE400se, following HiFiMAN's original purpose to offer great sounding products at a more competitive price to make it accessible to the most.

The HE400se is an open-back planar magnetic headphone that employs single-ended drivers to deliver a wide soundstage with accurate spatial imaging. With increased efficiency to 91dB, the HE400se performs as well with smartphones and tablets as it does with a full-size amplifier.

The HE400se inherits all the latest technologies from the HE400i 2020 and features our latest driver technology : the stealth magnets. This modification will improve the overall result by adding more clarity and bringing a more realistic spatial separation. It also makes it easier to drive so it can now be used with portable devices.

Why Choose A Dynamic Headphone…When You Can have Planar?

Dynamic headphones utilize conductors that vibrate in limited areas of the diaphragm. Result is that a large percentage of the diaphragm cannot be directly driven by those conductors.

Planar headphones have conductive layers over almost all of the diaphragm. Evenly driven by these conductors, result is significantly lower distortion than conventional dynamic headphones.
