Meet the HE400SE! Hifiman’s New $149 Planar Magnetic Headphone (Officially) Hits The U.S.!

Is This An Even Better Value Than The Hifiman HE4xx and HE400i?

If you’re looking to try planar magnetic cans on the cheap, Hifiman may have just the headphone for you. It’s called the HE400SE, and at $149, it offers one of the cheapest entry points to planar magnetic sound.

According to Hifiman, this new headphone is designed to supply a wide soundstage and accurate imaging, something models several times the HE400SE struggle to do. It also boasts a sensitivity rating of around 91db, which should allow it to be powered by portable devices.

The HE400SE is also said to be lightweight (13 ¾ oz), a trait that should aid in a comfortable wearing experience when combined with the tapered hybrid earpads.

This headphone has been available via overseas sellers since late last year, but now it will be available here in the U.S., cutting down on shipping costs and shipping time.

According to overseas reviews, the sound is similar to Hifiman’s popular Deva headphone, and it also uses a similar double-magnet planar driver. It also looks to have a similar yolk and headband style to the Deva.

Upon reading some impressions from the site, it seems like the HE400SE is considered a good value both in build and sound quality. If the US model is the same as the one sold in Asia, this new headphone should be very popular amongst budget-minded audiophiles.

Look for the HE400SE to be available both on and HIFIMAN’s online store sometime in April.
