By aspect — in detail
Tonality
Moderate · 18 srcNeutral-bright is the near-unanimous description, and most sources add that the brightness is evenly spread rather than peaky — Headfonics, Bloom, Exekuhtor and Fc-Construct all reach for "balanced" or "well controlled" alongside "bright". The dissent is sharp but narrow: Listener hears the low-treble emphasis of the original returned in full, and Audio46 says it "toes the line of being too bright". Both rigs agree the bass and mids sit flat and the tilt is upward.
“The HE6 Remastered has a bright-leaning tuning while still keeping the overall frequency balance quite even, with a clear focus on cleanliness and transparency.”
Nihal, Headfonics
“I hear the HE6R as neutral-bright, with a focus on clarity and an overall exceptionally well balanced tonality.”
Exekuhtor, Head-Fi review
“The profile toes the line of being too bright, but still strikes a good balance between highs and lows to make the signature engaging and immersive.”
Delaney Czernikowski, Audio46
Measured
Cuckoo Studio's head-and-torso rig reads the bass and mids as very flat against Harman 2013 with the whole curve tilted slightly upward; Fc-Construct's in-ear mics show no bass shelf, an elevated lower/mid treble and the usual HIFIMAN 2 kHz dip, and his overlays put it closer to the Susvara than to the HE600. HIFIMAN's own uncompensated overlay against the HE6se has the two traces on top of each other below 2 kHz, with the Remastered a little higher through the 3–5 kHz rise and above 10 kHz.
Sources split: the reviews and most owners hear deep, textured, physical bass — Bloom calls it among the best from HIFIMAN, a headphones.com owner says the sub-bass slams like no open planar he has tried — while both rigs, Fc-Construct, Resolve and the owners who came from an original or an HE6se V2 describe a flat, shelf-less low end that is tight rather than big. Nearly everyone agrees on two things: it extends deep, and it only fills out with a serious amplifier.
Measured
Cuckoo Studio measures the bass flat to Harman 2013 through the low end and mids — no shelf — and finds the response unchanged from a 1 Ω to a 600 Ω source, so amplifier differences are about headroom, not tonal balance. Fc-Construct's in-ear measurement extends cleanly into the sub-bass with no shelf, and shows HIFIMAN's $10 velour pads adding bass along with lower/mid treble.
⚠ vs. listeners — Both rigs show a flat bass, which is what the linear camp hears; the deep-bass camp is describing extension, texture and the way it fills out on a high-current amp, none of which a frequency-response line contradicts. The genuine disagreement is whether "flat and deep" earns the word slam.
Where it splits
deep, textured and physical — quality and depth over quantity63%
“There is real muscle here, but the bass never turns loose or overdone. Texture and definition are also excellent, and it is easy to pick up the finer details within bass notes.”
Nihal, Headfonics
linear and shelf-less — punchy, but not the bass monster of legend37%
“it had that neutral-bright signature HiFiMan is typically known for, but with some real solid weight and punch in the bass without having an actual bass shelf.”
Fc-Construct (Caleb), Head-Fi
Sources split, though lopsidedly: the clear majority hear a clean, transparent, slightly cool midrange with natural timbre and dense, well-placed vocals, and Audio46 and the loaner-tour listener find vocals forward and full. Listener hears the opposite — etched, grainy vocals and papery snares — and cactus_farmer found the mids slightly more scooped than the HE6se V2 in a same-amp A/B.
Measured
Flat through the mids against Harman 2013 on Cuckoo Studio's rig; Fc-Construct's in-ear trace shows the familiar HIFIMAN dip around 2 kHz, which the velour pads partly fill in.
Where it splits
clean, transparent and natural — clarity over warmth82%
“The HE6 Remastered takes a cleaner and more transparent approach. Vocals and instruments come through cleanly without any heaviness.”
Nihal, Headfonics
etched and grainy — the original's rough texture returned18%
“That said, for me snares in particular ended up coming across way too papery, and vocals felt really etched or grainy.”
Listener, headphones.com
Sources split: most hear an elevated treble that is unusually even for HIFIMAN — extended and airy, no narrow peak, bright without the fatigue the word implies — while Listener hears it as comically rough and scratchy with a 7–8 kHz resonance, Audio46 calls it quite sharp, and two owners find it brighter than they would like. The fault line tracks the low treble the original was known for: what one camp calls crispness the other calls scratch.
Measured
Cuckoo Studio reads the whole curve as tilted slightly upward and finds harmonic distortion negligible at normal level and 96 dB SPL, rising to roughly −47 dB in the mid/high band on its louder run. Fc-Construct's in-ear mics show an elevated lower and mid treble with upper-treble peaks he cautions are rig- and head-specific; the velour pads add about 2 dB up top. Listener's 7–8 kHz resonance was heard on his own head at a show.
⚠ vs. listeners — Neither rig shows a narrow peak — the lift is broad — which supports "evenly spread". The rough camp is describing a lower-treble emphasis that both rigs also show; Listener's point is that it is the same emphasis the original had, and whether that reads as crisp or scratchy is the listener's ear and pads.
Where it splits
elevated but refined — bright, evenly spread, non-fatiguing69%
“The HE6 Remastered has a treble-boosted profile, but it never feels exaggerated or harsh to me. I can see it getting a label of “bright headphones,” though the emphasis is evenly maintained.”
Nihal, Headfonics
rough, scratchy and fatiguing — the original's bite, unsoftened31%
“Now, to be clear, these are the exact same issues I had with the original HE6, in that the treble presentation is almost comically rough and scratchy.”

Soundstage
Moderate · 11 srcWide, open and tall by most accounts — MajorHiFi calls the spaciousness immense, Bloom hears a scaled-down Susvara, the loaner-tour listener was surprised a round-cup HIFIMAN staged this wide — and every reviewer with more than one amp says it grows with power. Fc-Construct is the outlier: more closed-in than HIFIMAN's egg-shaped models, limited height, shallow depth, and Headfonics concedes it is not as wide as an HD 800S.
“That is to say, they consistently rank among the best, and the HE6 Remastered confidently joins that list with its immense spaciousness.”
Alex Schiffer, MajorHiFi
“The soundstage is very big. I would even go as far and say that it rivals the egg-shaped Hifiman models that throw a big stage.”
Exekuhtor, Head-Fi review
“I have no complaints about the soundstage on the HE6 Remastered. It feels wide, open, and spacious without stretching things too far.”
Nihal, Headfonics
Imaging
Strong consensus · 9 srcThe strongest point of agreement after detail: precise placement, clean layering and instrument separation that survives busy passages. Even Fc-Construct, cool on the stage size, rates the horizontal imaging and separation as good.
“Imaging feels crisp and precise. Instruments have a clear position, and the whole musical picture feels very engaging and immersive.”
Nihal, Headfonics
“Layers of sound are separated with precision and grace, while instruments fold over and around each other for some excitingly dimensional imaging.”
Alex Schiffer, MajorHiFi
Detail
Strong consensus · 11 srcTop-tier resolution is the one claim nobody argues with — Exekuhtor puts it beside an original Susvara, Fc-Construct at 98–99 % of where diminishing returns flatten out, and owners on the loaner tour and in the thread single out low-level detail. The only qualification comes from Fc-Construct, who credits some of it to the forward treble.
“The imaging is also top tier, as well as the resolution. I'm not talking top tier in its price bracket, but in terms of overall planars.”
Exekuhtor, Head-Fi review
“The layering and separation is strong, and the overall presentation of detail is definitely a highlight of HE6 Remastered.”
Stephen Kostas, Bloom Audio
“A highly detailed headphone. It has excellent low level detail retrieval.”
Saberpunch, Head-Fi loaner tour
Dynamics
Contested · 15 srcSources split on the HE6's defining trait. Most hear the legend delivered: piano strikes with force, kick drums that hit like a truck, macrodynamic contrast Exekuhtor otherwise hears only from far dearer planars and electrostats — always with the caveat that it appears only on a high-current amp. Fc-Construct takes the opposite view, that a flat tuning cannot rattle teeth and the strength is low-level nuance, and the two listeners who compared it directly with the HE6se V2 call the extra slam exaggerated or absent.
Measured
83.5 dB sensitivity at 50 Ω, unchanged from the original. Cuckoo Studio's impedance sweep shows the response does not move between a 1 Ω and a 600 Ω source, so what an amp changes here is headroom and current, not frequency balance; distortion stays low up to 96 dB SPL and rises only on the louder run. Fc-Construct ran it near maximum volume on a $200 DAC/amp and heard only a marginal gain from a far more powerful one; speaker-tap owners hear a transformation.
⚠ vs. listeners — The slam camp's own explanation is amplification, and the counter-camp's A/Bs were on shared amps that drove both headphones equally — so the sibling comparisons cut against a driver-borne advantage while leaving the amp-scaling claim untested. No source has measured it on speaker taps.
Where it splits
summit-fi slam and macrodynamics — once the amp is up to it74%
“The dynamics are equally impressive. Piano strikes land with proper force and have enough body behind them. You can easily differentiate harder keystrokes’ sounds from softer ones. Drums hit with a solid sense of impact as well.”
Nihal, Headfonics
tight and linear — the extra slam over an HE6se V2 is marginal26%
“Reports of the increased slam of the HE6 are exaggerated. The HE6seV2 with these particular pads actually had a hair more tactile "slam" (perceived impact of kick drums and tom tom's for example) than the HE6, but slightly less sub bass rumble.”
cactus_farmer, Head-Fi
Comfort
Strong consensus · 9 srcFar more comfortable than 522 g implies, unanimously: the composite strap spreads the weight so well that Headfonics, Fc-Construct and the Japanese hands-on all say it does not feel heavy, and clamp is light. The caveats are specific — a loose fit for smaller heads, a headband some find short for large ones, pads that Bloom warns may not clear big earlobes, and warmth over long sessions.
“Personally, I find the HE6 Remastered to be quite comfortable. Even though the headphone is heavy, it does not feel uncomfortable due to the good weight distribution.”
Nihal, Headfonics
“The comfort is perfect for me. Its clampforce is on the lighter side, and I could see some people wanting to have a stronger clamp.”
Exekuhtor, Head-Fi review
“The headphones are lightweight, generally comfortable, and feature a good range of adjustments for head size, but if you have larger earlobes, the earpads might not be accommodating enough to fit your ears.”
Stephen Kostas, Bloom Audio
Measured
522 g by HIFIMAN's spec (550 g for the early original); kajetblog weighed its loaner at 518 g. Headfonics puts the HE600 at 389 g and the HD 800S at 330 g for scale.
Solid rather than luxurious. MajorHiFi reads glossy cups on aluminium yokes as the standard for the price and Bloom finds it more premium than an Arya Unveiled, but the same reviewers and owners list the plastic cup rings and grille, fingerprint-prone gloss, basic cables and a box with no case as thin for $1,899 — Headfonics calls the presentation bare-bones and Exekuhtor's own cons list says the build relies heavily on plastic. Nobody reports a failure yet; the headphone is two months old.
“It has glossy, reflective earcups and solid aluminum yokes that keep everything stable, as well as adding to durability.”
Alex Schiffer, MajorHiFi
“For headphones at this price, the presentation feels quite disappointing and bare-bones. You get the headphones and two cables, but nothing beyond that.”
Nihal, Headfonics
“The build quality is good to very good. Some people will hate on it, but honestly, I'll rather have some elegant and robust plastic than metal cups which scratch very easily.”
Exekuhtor, Head-Fi review
Isolation
Moderate · 2 srcFully open by design — one owner's praise is literally that it is "very open" — so there is no isolation and it leaks freely in both directions. Expected for the type, but it rules out shared rooms.
“Incredible headphone! The sub-bass slams like no truly openback (it’s very open) planar I’ve tried.”
Philip K., headphones.com verified owner
Sources split almost evenly. One side hears a Susvara-class planar at a third of the price and an easy recommendation for anyone with the amplifier; the other points at the HE6se V2 that sold for under $400 with the sibling driver, at the HE600 at less than half the price, at HIFIMAN's habit of discounting, and — in Listener's case — at more versatile headphones for the money. Everyone agrees the true cost includes the amplifier.
Measured
$1,899 at HIFIMAN's store and its dealers on 2026-09-17 (the 2010 original launched at $1,299; the HE6se V2 ended its run under $400). Headfonics' and Bloom's amp shortlists start around a Topping A900 or Cayin HA-3A and run to Questyle/Sendy and Ferrum stacks; several owners use speaker taps.
