Product Description

HiFiMan HE-400: Incredible Planar Magnet Sound With 92.5db efficiency, HiFiMan HE-400 Headphones can be driven by virtually anything (including an iPod). The familiar HiFiMan sonic signature provides a very detailed yet warm listening experience. Best of all, the HE-400 is priced far lower than many comparable cans, bringing true audiophile quality to the masses. "The best-sounding full-size, home headphones I've ever tested." - Steve Guttenberg, CNet.com "The open air design leads to a lovely soundstage- where you can hear and sense the space around instruments. The bass is solid, but not overwhelming, with excellent tightness...In the realm of planar headphones, the HE-400's represent a tremendous bargain. Not only have they lowered the cost of acquiring a pair of planar headphones, they have designed them in such a way that you don't need to spend even more money on an amplifier capable of driving them. Their ability to deliver beautiful music from smaller power sources is downright impressive. Highly recommended!" - Stephen Hornbrook, Secrets of Home Theater and High Fidelity "Because of the open-back design, the soundstage was wonderful. Plus, there was no hint of muddiness. I haven't heard Led Zeppelin sound so clear before....The HE-400 handled every genre of music, from classical to rock, like a champ. Everything I listened to sounded more fun, more detailed, more alive." - Bill Henderson, Gadgeteer

Customer Reviews

The HE-400's are very clean sounding compared to the Beats.
Blair Fritz
At the end of the day, the HE-400 is easily one of the best-- if not the best sounding headphone and complete package you can get at 400usd.
They have a great soundstage, they are very detailed, crisp clear highs and surprisingly good bass for an open headphone.
Alex Swedenburg

At 400usd, the HE-400 is the cheapest currently-marketed Planar Magnetic that high end audiophile company HiFiMan has produced yet. It's a result of their finally figuring out how to streamline manufacture a planar magnetic driver headphone. Their HE-4 offering is discontinued.

In case you don't already know, the fundamental way a Planar Magnetic Driver operates is that it uses a very large and light membrane to move air instead of a smaller, heavier cone/dome structure that other headphones use. The Amazon description says the HE-400 has a 50mm driver, but in actuality it has a 70mm driver. Instead of the membrane being moved by a small voice coil, it is placed between two huge arrays of magnets spanning its entire surface, leaving it to move in an isodynamic magnetic field. The advantages of this type of operation over conventional headphone drivers are tremendous: faster response, less distortion (especially in the bass range) and speaking of bass, Planar Magnetics and their huge, powerful drivers deliver tremendous bass extension and impact down low for open headphones. The HE-400 without a doubt has the best bass extension out of any open headphone I've heard outside Audeze's LCD-2. The only downsides of planar magnetics are weight and the fact that they're power hungry, so it's best to use a beefy amp with them.

The weight is not a big deal for the HE-400, it is lighter than the higher end planar magnetics, the headband disperses weight very evenly so there's never a pressure point buildup on the top of your head, and the earpads are very big and spacious, so your ears never touch the drivers. The build quality and appearance of the HE-400 screams high end to me. It's a very sturdy feeling headphone that also has a very high-tech draw to it.

Okay so I have owned these headphones for the better part of 6 months now and am pretty sure I am clear on their sound signature.
First off I bought the HE400 around July of 2012. After purchasing the He400 I also acquired the creme dela creme of Orthodynamic headphones, the Audeze LCD2 (Revision 2).

After using mostly dynamic headphones like Denon D5000's and Sennheiser HD650's for the past few years the most striking and obvious thing with the He400 is the clarity... Detail and dynamics are amazing clear and articulate.

They are relatively efficient headphones and can be powered by an iPod headphone jack but sound much better with a portable headphone amp if you are using your iPod. That said they really don't shine until hooked up to a more powerful source. I run mine with poth an ALO Audio National portable amp and a Violectric V100 desktop headphone amp.

Through either the iPod or the Alo amp, the Audeze were clearly most proficient with technicalities. More dynamic low frequency passages ala dubstep or industrial electronic rock got a little frayed at the edges with the HE400's whereas with the Audeze you could really see all the way down to the bottom and all the way to the top of the recording wonderfully. Both are clear, both have decent bass and slam but the Audeze LCD2 have a much faster much more resolving sound.

The one GIANT caveat with that is that as long as you aren't sending the HE400 into fits with an underpowered amp that can exert solid control over its diaphragm via sufficient current, the He400 has a more engaging, live sounding and forward tone than the LCD2. The Audeze can articulate clearly and perfectly the most low lows on any recording...

If you're looking for technical details, I'll leave it to others who know far more. I'll just provide a qualitative review. For background, I'm somewhat of an audiophile - have separate pre-amps feeding power amps, going to decent speakers. Play only cds or lossless files. Was agonizing over the past few months, trying to figure out what new headphones to get. Had a few major decisions to make first.

Open back versus closed back. Went for open back, since I already have closed back headphones for travel purposes. Wanted more of an audiophile experience with the new pair, and all the headphones out there rated as "audiophile" seem to be open back.

Dynamic versus ortho. Went back and forth between Sennheiser HD650 at $499 (dynamic), AKG Q701 at $250 (dynamic) and HiFiMan HE-400 at $399 (ortho). At the end of the day, based on how reviews were written, I decided that I probably wanted the orthos, smooth, responsive, good tight bass, and potentially "warmer" through the vocals (really what I wanted to buy after reading all the reviews were the Audeze LCD2s, but I did not have $995 lying around!).

The headphones arrived, and they have been outstanding.

Yes, they are big. FIrst words out of my son's mouth: "They're huge!" FIrst words out of his friend's mouths "Wow, they're huge". But they are super comfortable. Really, despite the size, not a problem.

The sound is as transparent, and as detailed as all the reviews state. My son, who borrowed them, had to stop wearing them while he was doing homework - "I can't concentrate on my work - I'm hearing the music" - and went back to his Beats.

I have to focus a little more if I'm reading while I'm listening through them - the music is so amazing, it demands your attention.
