A Lightweight Planar Magnetic Experience

HIFIMAN has taken its HE-400 series to new heights. Introducing the HE-400i: a pair of planar magnetic headphones optimized for critical listening and uncompromising comfort. Touted by HIFIMAN as 30-percent lighter than competing full-size planar magnetic models, the HE-400i drastically reduces fatigue while retaining a premium over-ear feel. Newly designed, beveled earpads made from pleather and velour optimize comfort and sound quality, while an extra-wide headband evenly distributes pressure on the head. A single-ended planar magnetic design delivers a wide-open soundstage with impressive spatial imaging and precise, neutral clarity across all frequencies. Featuring improved 93-decibel sensitivity and a newly added 3.5-millimeter jack, the highly responsive HE-400i works well when connected directly to any portable device, or when paired with a small-to-mid-sized amplifier.

Note: This run is for the 3.5-millimeter connector version of the Hifiman HE-400i.

HIFIMAN: The Name Audiophiles Trust

Born in New York City in 2007, HIFIMAN has had a big influence on the audiophile world, and founder Dr. Fang has always had close ties with the community. He started out on Head-Fi and attended local meetups while pursuing his doctorate at Columbia. When he realized his PhD research could be relevant to his passion—the music-listening experience and the audiophile products that improve it—he started talking with forum members and meetup attendees about what they’d like to see in the next generation of headphones. Since then, the company has been featured in TIME, Forbes, and CNET’s “The Audiophiliac,” and won the CES Editors’ Choice Award. HIFIMAN is a natural partner for Drop because our goals are so aligned. At its core, it represents a passionate audiophile building a company that serves the rest of the community.

I promise to let you know! I bought the HE-4XX from Drop last year. I found them to be very "utilitarian" and kinda a rough draft, or what appears to be an unfinished version. They do sound very...Read More

No, the 2020 revision doesn't have the suspension headband and instead has a solid arch. Though it doesn't have the old leather like box.Read More

Just in case anyone else is wondering about this question, I have tried the HE400se, He400i (both 2016 and 2020 versions), and the HE4XX, as well as many Hifiman headphones all the way up the chain, and aside from the OG HE400, the 2016 HE400is are my favorites from the HE400 series. The 400se is a much drier sounding headphone that comes across as a bit more neutral in comparison. The 4XX is a warmer sounding headphone that sounds a bit veiled and seems tonlose some of the detail especially through the mids. The 2020 version of the HE400i sounds nearly identical to the 2016 with some very minor differences that are so small that they aren't even audible on many tracks, but they are significantly less comfortable than the 2016 version with the suspension headband. I also think the HE400i scales with better signal chains to a greater extent than the HE400se, though I can't comment on how the HE4XX scales because I didn't get as much time with varied gear when I had them around. If I was looking to purchase an HE400 headphone today and wasn't willing to pickup a used OG HE400, then I would definitely buy my 2016 HE400is all over again without a doubt. I actually like them quite a bit more than the HE5XX. That said, with versions if the HE560 and the Sundaras available for under $300 brand new these days, it makes sense to start with them *if* your budget allows (I prefer the HE560s and find the Sundaras a bit too bright, but that's for another post). The 2016 HE400is are still a very relevant headphone in today's market and they're a great, exceptionally comfortable budget planar. ***Disclaimer: All of this is just my opinion based on my experiences and, as with anything in audio and head gear, YMMV.
