HIFIMAN HE1000se Review: The $1,700 Flagship Planar

Named Best Overall in our Best Open-Back Headphones guide, ahead of 13 others.

I've tested a lot of headphones, and only a handful have ever sent me back to re-listen to my whole library. The HIFIMAN HE1000se is one of them. It isn't built to sound good - it's built to sound true. So the real question isn't whether it's good. It's whether you want a headphone this honest.

A light metal build and excellent comfort

Watch this part (0:32)

The HE1000se arrives more like a luxury watch than a pair of headphones. The box is wrapped in real brown leather, and the manual tucked next to the headphone isn't really a manual at all - it's closer to a coffee-table book, full of photographs of opera houses. The "se" stands for Special Edition. It launched as a flagship at around $3,500, and now it sells for just $1,700. Inside you also get three cables: a long quarter-inch cable for desktop gear, a short right-angle 3.5-millimeter cable for portable use, and a balanced XLR. It's a genuinely generous set - and unlike the older HE1000 cables, which came in thin, medical-looking silicone tubing, these are a real step up. They're fabric-wrapped, all black, and they finally look and feel like cables that belong with a headphone at this level.

Pick the headphone up and the first surprise is that it's lighter than it looks - around 440 grams, which for a full-size planar magnetic is genuinely not heavy. The whole frame is metal, CNC-machined and then hand-finished by HIFIMAN's craftsmen, and you feel it the moment it's in your hands, because the cheaper models in the range lean on plastic. The cups swivel with a smooth, well-damped motion - no squeaks, no flex, no strange noises. There's one small detail I love: the cable sockets are angled by about ten degrees, so the cables fall away from your face instead of putting pressure on the connection. It's a tiny thing, but it's the kind of tiny thing that tells you someone actually thought about wearing these for hours.

And then there's the wood. The cups are finished with a band of wood veneer, and next to the silver aluminum it looks gorgeous - honestly, almost identical to HIFIMAN's flagship Susvara, which to my eye is one of the best-looking headphones they've ever built.

Comfort is where this headphone quietly wins. It's one of the most comfortable headphones I've ever worn. The headband is wide enough to spread the weight across the top of your head, and you stop noticing it within a few minutes. The pads do the rest: they're deep, huge, and soft, angled to sit flat against your face, and built from a combination of leather on the outside, breathable cloth where they touch your skin, and perforated leather on the inside. Four hours in, your ears aren't hot or sweaty.

There are a couple of things to watch for. When they're new the clamp is a little tight - more so if you wear glasses, like me - but give it some time and it loosens up. The one I'd actually pay attention to is size. These cups are big. If you have a smaller head, the bottom edge can end up resting on your jaw instead of sitting cleanly around your ear.

Neodymium Stealth Magnets give the film more grip

Watch this part (3:24)

It's worth knowing what's inside, because with the HE1000se the technology is the whole point. It starts with the diaphragm - the thin film that actually makes the sound. HIFIMAN got theirs down to about a nanometer thick. How thin is that? Turn it on its edge and you can't even see it. And the thinner the film, the faster it moves, which means more detail and less distortion.

Then there are the magnets. In most planar headphones the magnets sit right in the path of the sound and create turbulence that smears the detail. HIFIMAN reshaped theirs so the sound slips straight through - Stealth Magnets, so called because acoustically they all but vanish.

Here's the interesting part. HIFIMAN's no-limits flagship is the Susvara - far pricier and far harder to drive. The HE1000se takes that same Stealth Magnet and nanometer-diaphragm thinking and adds neodymium magnets: stronger magnets in a smaller, lighter package. More grip on the film means it moves faster and hits harder without needing a monster amp to wake it up. It takes the flagship ideas and makes them far easier to live with.

And that grille on the back is the Window Shade system we know from other HIFIMANs. It protects the driver while keeping the cup wide open, so the sound escapes cleanly instead of bouncing back inside.

Easier-to-drive specs than the HE1000 V2

Watch this part (5:03)

If you're worried about drivability, two numbers tell you how hard a headphone is to power: impedance and sensitivity. The HE1000se comes in at 35 ohms and 96 decibels, which in plain terms makes it one of the more cooperative flagship planars out there. The older HE1000 V2 was tougher to drive - this one is about 5 decibels more sensitive, so you don't need a big, expensive amp to wake it up. A good dongle or a modest desktop amp will get it loud and happy.

But here's the catch: easy to drive isn't the same as easy to please. The HE1000se is transparent enough to pass along hiss or grain from a cheap, noisy source. It doesn't ask for much power, but it does want a clean signal to really shine. Power it's relaxed about; quality, not so much.

Frequency range is 8 hertz to 65 kilohertz, far beyond what anyone can actually hear, so you won't notice those extremes directly. And on a practical note, these are fully open-back, which means zero noise isolation for you and maximum sound bleed for everyone nearby.

State-of-the-art detail and a bright top end

Watch this part (6:22)

As I said at the start, this thing isn't built to sound good - it's built to sound true. This is where that pays off, and occasionally where it bites.

Start with the big one, because it's the whole reason this headphone exists: detail. This is state-of-the-art detail retrieval. It pulls tiny things out of a track - the scrape of a finger on a string, the air around a voice, a background layer buried deep in the mix - and lays them out so clearly that you'll catch things in songs you've known for years. A lot of that is speed. Notes start and stop instantly, so plucked strings and percussion sound sharp and real, and even busy, crowded tracks stay clean - you can follow one instrument in an orchestra full of them without losing it.

The bass is fast, clean, and dead-linear. It goes deep, it hits hard when the track asks for it, and it's some of the tightest, most controlled bass you'll get from a planar. But it's reference bass, not basshead bass. There's no extra energy added for fun - this headphone chases realism over impact, and it can feel a touch bass-light. If you want something that slams for the sake of slamming, this isn't it.

The mids are neutral and honest. Vocals sit slightly forward, clean and beautifully separated, so with two or more singers you can pick each one out on their own. Pianos have real weight, string instruments have that little vibration that makes them feel alive, and properly recorded voices sound unreal. If I'm nitpicking, it can run a touch lean - a little more warmth and body would make it even more inviting - but nothing here sounds wrong.

The soundstage is where the HE1000se really shows off. It's big, open, and holographic - the most spacious presentation in HIFIMAN's egg-shaped lineup. It doesn't just throw sound out wide; it wraps it around you. Instead of laying the music out in front of you, it makes you feel like you're standing in the middle of it. Imaging is pinpoint - every sound has a precise, locked-in spot, and you never have to hunt for it. On big, layered music - orchestral, live, jazz - it's spectacular.

There's a catch, and it's the treble. The HE1000se is a bright headphone, and up top there's real energy, with some genuine spikes in the highest frequencies. On a great recording that comes across as air, sparkle, and stunning detail. On a bright or poorly mastered one, it can turn intense and unpleasant. If you're treble-sensitive, long sessions can fatigue you.

This is the one thing to know before you buy: the HE1000se is not forgiving. Feed it clean, well-mastered music and it's breathtaking. Feed it garbage, and it will happily show you every flaw in that garbage.

The smoother Arya Unveiled gives up detail

Watch this part (10:12)

So who's it for? If you love detail, resolution, a huge, tall stage, and honesty above everything - and you mostly listen to well-recorded music - this is one of the best you can buy for the money.

If you want warmth and forgiveness, the Arya Unveiled is the better fit. It's a newer HIFIMAN headphone that costs less than the HE1000se, and its big change is the treble: HIFIMAN calmed down the sharp, bright top end this headphone is known for. The result is smoother and easier on the ears, with a little more bass and fuller mids - the one you can listen to all day without any fatigue. The catch is that all that smoothness costs you some detail.

For me, the HE1000se is the one I keep reaching for, largely because most of what I listen to is good-quality material. If that's you too, you'll love it. And if it isn't - now you know exactly what to get instead.
