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, "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

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...

Ok, so this is probably the happiest review I'll ever give!! I'm not gonna lie the hype was a bit much and lets just say I was fooled before.. (beats) So after a while of waiting and reading I decided to pull the trigger and boy was I happy. The first thing you notice is the size and weight and the second thing you notice is that it doesnt matter. They are huge huge cans but you could care-a-less once the music starts. These are as close to perfect as one can get for under a grand. They are literally do-it-all headphones.

I'll admit I am a bit of a bass head but clearly I'm not dumb (clearly). Bass is very very important to me but I still need substance not just sub bass. I didn't know what to expect because I was once told that V-Moda's had amazing bass and then traded them back in two days after I got them because of how weak they were so when I read that these "had" the bass that I was looking for I was a little skeptical but wanted to give them a shot nonetheless.. And again.. WOW.. The impact, the speed and the depth is pretty amazing and oh so clean.. Are there other headphones that hit harder for the money or less?? Of course!! The Ultrasone Pro 900 are the first to come to mind but do can the Pro's hold the 400's lets say "magnets" (you guys know what I mean) not even close!! The overall sound signature of the pro's is kitty litter compared to the Hifiman's. They managed to find the perfect balance and no part of the sound bleeds into the other but there is still enough bass for your everyday (now) upscale bass-head to love.

Of couse the first thing I did when I was on the road to buy the headphones was to buy the replacement velour ear pads from ([...]) and that was the smartest thing I could have done.
