The short version

What to know.

A large open-back planar that everyone agrees resolves like a flagship and nobody describes the same way. The points of consensus are firm: reference-grade detail and transparency, precise imaging and layering, genuine sub-bass extension — flat to 20 Hz with a small mid-bass lift rather than a bass shelf, and more low end than any HE1000 before it — and long-session comfort despite 458 g, provided your head is not small. Its measured shape is agreed too, across three separate rigs: a dip through roughly 1.5-2 kHz (about 4-5 dB below a Harman-style target), a lifted upper midrange around 3 kHz, and an air region several dB above target, which makes it a bright headphone by any reading. What that shape sounds like is where sources part company, three times over. Tonality splits almost evenly between warm-and-U-shaped and neutral-to-bright reference. The midrange divides harder: most sources hear it as politely recessed and a minority as outright thin, while a substantial camp — including the one reviewer who bought his own pair — hears vocals as forward and unusually lifelike. The treble is the loudest argument: two-thirds call it airy, refined and among the least fatiguing HIFIMAN has made, while a third, led by the harshest measurement source, finds it genuinely tiring on bright material. Soundstage is nearly as unsettled — enormous and speaker-like to most, no wider than the older HE1000s to several, and outright narrow to one outlet. Some of that traces to things a buyer can control: it is unusually position-sensitive on the head, it changes character with amplification, aftermarket pads even out the midrange, and both camps converge on the same EQ (fill 1.5-2 kHz, shelve the top down a little). Build is solid but not luxurious, the accessories are thin for the money, and HIFIMAN's reliability reputation shadows it even though owners report years of trouble-free use. Easy to drive on paper at 32 Ω, it audibly scales with real power, and being open-back it isolates nothing. At $2,999 it was a hard sell; at $949 direct — and $600-800 used — most of the value objection has evaporated, with the standing counter-argument being HIFIMAN's own far cheaper Edition XS and Ananda.

About this product

The HE1000 Stealth Magnet Version — the 2015 HE1000 V2 shell and driver given HIFIMAN's acoustically-invisible stealth magnets, released in China in late 2022 and internationally in early 2023. It is NOT the HE1000se, which also has stealth magnets, is easier to drive and still costs more; and the widespread name 'HE1000 V3' is a retailer and forum invention rather than a HIFIMAN model. The line now runs HE1000 (2015), HE1000 V2, HE1000se, this, and the grille-less HE1000 Unveiled, with an HE1000 WiFi alongside — all sold or supported concurrently, so 'the HE1000' is a shelf rather than a model. Listed at $2,999 by HIFIMAN, sold near $2,000 early on, quoted at $1,399 by nearly every review, and $949 direct as of mid-2026. Specs: open-back planar, 8 Hz-65 kHz, 32 Ω (31.5 Ω measured), 93 dB/mW, 458 g, dual 3.5 mm TRS connectors, 6.35 mm and 4-pin XLR cables in the box, two-year warranty. One later production change is documented rather than announced: mid-2023 units ship a black stock cable in place of the earlier rubber-sheathed one.

HIFIMAN's HE1000 Stealth is the egg-shaped 2015 flagship brought forward: the HE1000 V2 body and its nanometre-thickness planar diaphragm, rebuilt around the acoustically-invisible stealth magnets that have since spread across the whole HIFIMAN range. It is not the HE1000se, which also uses those magnets, and it is not the 'HE1000 V3' that half the internet calls it — a name HIFIMAN has never used.

What makes it worth mapping is not the technology but the disagreement. It launched at $2,999, spent most of its reviewed life at $1,399, and sells for $949 direct today, so the value argument keeps shifting under it. And the sound divides people unusually hard: reviewers who agree completely about its resolution, imaging and comfort will tell you in the same breath that it is warm or that it is neutral-bright, that its vocals sit back or sit forward, that its stage is the widest they have heard or narrower than average. One owner on Audio Science Review eventually wrote what everyone else was circling: he was surprised how little consensus there is about it.

A good fit for

Listeners who want flagship-level resolution and imaging for well under flagship money
Anyone who found the HE1000se or Arya Stealth too bright, too lean, or too shouty
Classical, jazz and acoustic listeners — instruments and space are what every source praises
People with a real desktop amp, ideally a warm solid-state or tube stage, which every source says it wants
EQ users: filling 1.5-2 kHz and shelving the treble slightly are well-documented, effective fixes
Long-session listeners with average-to-large heads
Bargain hunters — $949 direct, and $600-800 used, for a headphone that listed at $2,999

Think twice if

You're treble-sensitive: it measures bright everywhere, and a third of sources find it fatiguing
Vocals are your priority and you want them front and centre without reaching for EQ
You want mid-bass slam — this is deep and fast, not punchy in the dynamic-driver sense
Your only source is a phone, a dongle or a small portable; it plays, but nobody thinks it opens up
You have a small head or face — several sources say it does not fit well even at the shortest setting
You need isolation, or you listen where leakage would bother somebody
You want luxury packaging, a case and decent cables with your four-figure headphone

Common ground12

Reference-grade resolution, micro-detail and transparency — the trait nobody disputes, and the reason the HE1000 name still means something.
Precise imaging with excellent separation, layering and a solid centre image.
Real sub-bass extension: flat to 20 Hz with a small 50-120 Hz lift, and more low end than any HE1000 before it.
Bass quality is excellent — fast, tight and textured — but it is precision rather than slam.
It measures bright: the air region sits several dB above a Harman-style target on every rig that has measured it.
The dip through 1.5-2 kHz is real and consistent across three independent measurements.
It responds well to EQ, and both camps prescribe the same thing: fill 1.5-2 kHz, shelve the top end down a little.
A big, open, out-of-head presentation with genuine depth and height.
Comfortable for hours despite 458 g, thanks to the wide suspension strap and very large pads.
Easy to drive on paper at 32 Ω and 93 dB/mW, yet it audibly scales with a proper desktop amp.
Well made and serviceable but not luxurious, and the box, case and cables are thin for the price.
Open-back: no isolation, leaks both ways, by design.

Points of contention5

Tonality: warm and U-shaped to roughly half the sources, neutral-to-bright reference to the other half — one curve, two reference points.
Mids: politely recessed to about two-thirds, and thin or tinny to the harshest of them — or forward, vivid and the best thing it does, to the rest.
Treble: air and sparkle that never fatigues to two-thirds of sources, real fatigue to a third led by the harshest measurement rig.
How it ranks against the older HE1000 V2 and SE for stage width: no wider or slightly pulled in to several, outright narrow to one outlet, the biggest stage they have heard to others.
Whether it is a bargain or a diminishing-returns trap next to HIFIMAN's own much cheaper Edition XS and Ananda.

The measured shape is not in dispute — bass a touch above its own midrange, a dip through 1.5-2 kHz, a lifted upper midrange and an elevated air region. What to call it is. Sources split close to evenly: one camp hears a warm, U-shaped, notably un-HIFIMAN tuning and treats that as the whole point of this model; the other hears a neutral-to-bright reference headphone with very little colouration. Both camps mostly like it, which is why the split is about description rather than quality — and it is the single most confusing thing about the HE1000 Stealth online.

Measured

Three rigs agree on the contour. oratory1990's data (archived in AutoEq), level-matched to the Harman over-ear 2018 target across 200 Hz-1 kHz, sits about 4.5 dB below target from 20-40 Hz, 3.7 dB below through 1.2-2.2 kHz, 1 dB above around 3 kHz and 3.5 dB above from 10-16 kHz; against the headphone's own midrange the bass is only +1.3 dB at 65 Hz. TechPowerUp reads the same thing subjectively as a tilt: 'It comes off more U-shaped rather than neutral-bright'. The Headphone List, hearing it as neutral, still concedes 'According to the frequency graph, it is subtly U-Shaped.'

vs. listeners — Both camps are describing one curve from different reference points. Measured against a bass-boosted Harman target it is a bright, bass-light headphone; measured against its own midrange — or against the HE1000se and Arya Stealth its listeners actually owned — it is the warm one. Neither camp is misreading the graph; they are standing in different places.

Where it splits

Warm and U-shaped — the bassiest, most forgiving egg-shaped HIFIMAN, and better for it.46%

“There’s also a noticeable increase in warmth from the bass, lending an ‘organic’ feel to the sound, if you like.”
unheardlab (sai)

Neutral to neutral-bright — a reference tuning that happens to measure as a gentle U.54%

“It feels truly neutral. There’s honesty to it, with very little coloration.”
The Headphone List (Pinky Powers)

The most consistent praise in the set, and the clearest break from the HE1000se: flat extension to 20 Hz with a small lift through 50-120 Hz, fast, tight and textured, with real sub-bass rumble rather than mid-bass thump. Every source rates it well; the honest caveat, repeated by several, is that this is precision rather than muscle — it will not slam like a big dynamic driver, and how much bass you think there is depends entirely on what you are comparing it to.

“Notice how the mid-bass rises slightly compared to the mids and this continues into the sub-bass too.”
TechPowerUp (VSG)

“phenomenal bass, both quantity and quality”
Head-Fi (Mista Lova Lova)

“the low-end of the HE1000 Stealth is of a rather lean nature and focuses on precision, clarity and definition rather than raw muscle and mass”
hxosplus (Ichos)

Measured

A lift, not a shelf. unheardlab measures 'There’s a touch of added bloom, evidenced by a lift around 50-120Hz.' and 'Beyond this, it remains very linear, extending down to 10Hz with minimal roll-off.' oratory1990's data agrees: +1.3 dB at 65 Hz over the headphone's own 200 Hz-1 kHz level and only -0.5 dB at 20 Hz, yet roughly 4.5 dB under a Harman-style bass shelf from 20-40 Hz. Headfonia confirms the direction against the sibling — 'Looking at the FR curves you will see the SE has lighter bass presence than the Stealth'.

vs. listeners — The apparent argument about quantity is a reference-point argument, and the graph settles it. Against every other egg-shaped HIFIMAN this has more bass, which is why owners of the HE1000se and Arya call it bassy and one calls the sub-bass boost 'the only consensus' about the headphone. Against a bass-boosted target or a dynamic-driver flagship it is several dB light, which is why the same low end reads as lean. It also EQs up cleanly, since there is no roll-off to fight.

Mids

Band: opinion spread · Dot: weighted average

The hardest split, and the one most likely to decide a purchase. Nearly two-thirds of the weighted sources hear the midrange as politely set back — 'reserved', 'conservatively tuned', and at the negative end thin and tinny on the wrong recording, with male vocals the usual casualty. The rest hear vocals as forward, lively and among the most lifelike they have heard. The measured dip is real and both camps are listening to it; one ASR owner in the recessed camp goes so far as to say he likes the recession and deliberately leaves it alone.

Measured

The dip is measured and consistent: oratory1990's data runs 3.7 dB under the Harman over-ear 2018 target through 1.2-2.2 kHz, deepest at about 5.5 dB down near 1.87 kHz, while 2.5-4 kHz sits slightly above it. TechPowerUp ties the audible effect to the same feature — 'The now-traditional HIFIMAN dip at 1 kHz contributes to this too by taking away from body and weight from vocals' — and the EQ prescriptions converge on filling it: sai uses a +5 to +6.5 dB peak at 1.9 kHz, oratory1990's preset does the same, and ASR posters land on +3.4 dB around 1,800 Hz.

vs. listeners — One curve produces both experiences because two things happen at once: 1.5-2 kHz is pulled down while the upper midrange around 3 kHz is pushed up. Vocal presence and sibilance move forward; vocal body and chest weight move back. Which of those you notice depends on your music and your ears — and on physical variables the sources name themselves: unheardlab's positional-variation measurements show placement on the head shifting the balance, The Headphone List needed to wear it further back than any other headphone to get it right, and aftermarket pads measurably even the region out.

Where it splits

Politely recessed — vocals sit back, and on bright recordings they can turn thin.63%

“while generally natural, it’s slightly reserved and polite in terms of presence”
unheardlab (sai)

Forward and lifelike — vocals are the best thing it does.37%

“Her airy, angelic voice is vivid and pure, directly in front you.”

Everyone agrees it is bright; they do not agree on what that costs. Two-thirds of the weighted sources hear air, sparkle and refinement, and several rank it the least fatiguing treble HIFIMAN has made outside the Susvara. A third — led by the source with the harshest measurement rig — finds it genuinely fatiguing, and two owners report having to keep the volume down or reach for EQ. Notably the camps do not track expertise: the two industry-standard measurement sets sit on the 'smooth' side and one in-house rig sits on the 'too bright' side.

Measured

The elevation is real on every rig — oratory1990's data averages 3.5 dB above the Harman over-ear 2018 target from 10-16 kHz, peaking about 5.8 dB up near 12.3 kHz, with narrower peaks oratory1990 places at 5.1 kHz and 7.9 kHz. Its shape is what the smooth camp points to: unheardlab finds 'As you can see the overall contour of the treble follows a downward trend from 4kHz to 14kHz.' — elevated overall, but without the 12 kHz dagger of the HE1000 V2. TechPowerUp's fix is 'a broad EQ shelf of around -3 dB from 6 kHz onward'; sai's is a set of 2-3 dB cuts at 4.9, 7.3 and 12 kHz.

vs. listeners — This is the split that the measurements explain best, and the explanation is the rig. sai notes his readings — taken on the same industry-standard setup oratory1990 uses — came out milder than the ones circulating from in-house rigs, and that he cannot separate unit variation, silent revisions and rig differences as the cause. So the same headphone is honestly reported as 'the least fatiguing HIFIMAN egg' and as 'fatiguing', and a listener's own tolerance decides which description they will recognise.

Where it splits

Bright but smooth — airy and extended without fatigue, and tamer than the HE1000se or Arya.66%

“this is arguably the most unfatiguing treble rendition I’ve encountered yet in the Hifiman egg-shaped lineup”
unheardlab (sai)

Overly bright — the lift tips into real fatigue, and it is a dealbreaker for sensitive ears.34%

“the HE1000 Stealth is unfortunately leaning overly bright to the point of being fatiguing”
TechPowerUp (VSG)

What to keep in mind 9

A read of where the reviews land as of late July 2026 — the HE1000 Stealth arrived in early 2023, and HIFIMAN has since stacked the HE1000 Unveiled and HE1000 WiFi above it.
The price is the moving part: $2,999 list, around $2,000 early on, $1,399 through almost all of its reviewed life, and $949 direct as of this writing, with used pairs trading about $600-800. Nearly every value verdict here was written at the higher numbers.
Impressions of this headphone conflict more than most, and owners say so themselves — the splits on tonality, vocals and stage width are real disagreements between careful listeners, not somebody getting it wrong.
Test rigs read its top end differently, and the two industry-standard ones agree with each other more than with rigs built in-house. That is part of why 'lovely air' and 'fatiguing' can both be honest descriptions of the same treble.
Reviewers heard it on wildly different gear — tube amps, big desktop solid state, dongles, portable players — and several say the treble and the stage change a great deal with the source. It plays from anything; it opens up only with real power.
Where you put it on your head changes the tonal balance, more than with most headphones, and the sweet spot sits further back than usual. A couple of sources also found aftermarket pads even out the midrange.
The cups are very large. Several sources warn it does not suit small heads or faces even at the shortest headband setting.
HIFIMAN's reliability reputation comes up in almost every owner account, including from owners who have had two trouble-free years — buying somewhere with a warranty and easy returns is the usual advice.
Most reviewers received their unit free from the maker; the two who bought their own are the self-purchased outlet review and the owner accounts, and enthusiast ratings skew positive in general.
