By aspect — in detail
Broadly agreed to be a deliberately coloured tuning rather than a neutral reference: a V/U-shaped or 'smiley' balance with lifted bass, a bright presence/treble region and slightly attenuated mids. Most reviewers call it clearly non-neutral (fun, or at least useful once you adapt); a minority read it as more natural and linear. The measurements side with the 'not neutral' camp.
“a classic “smiley face” curve with increased bass and treble, but attenuated high-mids”
Sonarworks
“The mids and highs are very balanced and linear.”
proaudio.tech (Peter Kaminski)
Measured
Measures as a mild 'smiley'/U-shape: Sonarworks found it far enough from neutral that its calibration applied “the first time our calibration has applied a significant bass cut to an open-back headphone profile,” and Sound On Sound heard “a definite lift somewhere around the 100Hz region and a prominent treble boost above 5kHz or so.”
The headphone's signature trait, and a genuine fault line. Everyone agrees the bass is unusually elevated and deep for an open-back — real sub-bass most open-backs can't manage. The split is on quality: one camp hears it as punchy, extended and well-controlled; another hears simply too much, and at times woolly or 'one-note,' especially on busy tracks or weaker sources.
Measured
The low end measures well above the open-back norm — Sonarworks notes “this marks the first time our calibration has applied a significant bass cut to an open-back headphone profile,” and SoundGuys measures a “gradually ramping overemphasis from about 800Hz on down.” Sound On Sound heard the flip side: the bass “sometimes seemed rather woolly,” with “something of a ‘one note’ quality.”
Where it splits
Deep, punchy and unusually extended — the party trick.64%
“I don't know of many open-backs that has the amount of sub-bass and mid-bass quantity that this MDR-MV1 has, and that's the most impressive thing about this headphone.”
Audio Discourse (Antdroid)
Too much — and not always clean; woolly or one-note.36%
“the Sony MDR-MV1 has too much, with a gradually ramping overemphasis from about 800Hz on down.”
SoundGuys (Christian Thomas)
Slightly recessed — the dip of the U/smiley — which most reviewers find natural but set a little back rather than forward. Opinions on whether that matters split mildly: some enjoy the more distant, laid-back stage it creates, while others feel vocals sit too far behind the boosted bass and treble. Not a mid-forward headphone.
“The mid-range has a slightly recessed tuning, much like what you'd expect from listening to a Hifiman, Audeze, or something like the Sennheiser HD800S”
Audio Discourse (Antdroid)
“The mids are surprisingly good and clear.”
r/headphones (Audiobernd)
Measured
The recessed mids are the trough of the U-shape — Sonarworks measures the high-mids as “attenuated” relative to the boosted bass and treble, and Audio Discourse frames the whole balance as an “aggressive U-Shape.”
The central argument. Measurements agree on a lifted presence/lower-treble region around 6 kHz, so nearly everyone hears the MV1 as bright — but they split hard on whether that brightness is a fatiguing peak or an easily-tolerated, non-sibilant energy. One camp (backed by the graphs) calls it a real, hot peak; another listens for hours without fatigue and reports no sibilance. Either way, it EQs down easily.
Measured
The peak is physically there: ASR measures “a horrible peak at 6kHz,” Major HiFi isolates an extra upper-treble “buzz” to “somewhere between 12 – 14 kHz,” and SoundGuys measures the highs “from 5kHz and up” as pronounced. Reviewers on the calmer side stress it “EQs out easily.”
⚠ vs. listeners — The 6 kHz lift is real, but whether it reads as harsh depends on ears, source and how the memory-foam pads compress on a given head — the same region ASR calls “a horrible peak” is one Audio Discourse hears with “no sibilance in even the worst tracks I tried.”
Where it splits
Bright to a fault — a genuine ~6 kHz peak that can bite or fatigue.58%
“Well, this is a horrible peak at 6kHz (and a huge dip at 4.5kHZ). Generally it seems that it is on the bright side, even big time.”
Audio Science Review forum (Jochen)
Bright but civil — no sibilance, non-fatiguing, and easy to EQ.42%
“I don't find this headphone fatiguing at all, and I listen to it for hours on end without pause”

Soundstage
Contested · 8 srcA real fault line, made more interesting because spatial presentation is the MV1's whole design goal. Some reviewers hear an open, spacious stage that's wider than a typical studio can — bigger than an HD 600 — while others hear it as intimate and forward, precise but not wide. Its immersiveness for surround/3D material tends to score higher than its raw stereo width.
Measured
Tuned for spatial work rather than width: Sound On Sound notes “the emphasis is on accurate spatial presentation within a stereo and surround soundfield, rather than on presenting the most neutral frequency response,” and SoundGuys found “where the Sony MDR-MV1 shines is immersiveness.”
Where it splits
Open and spacious — wider than typical studio cans.54%
“The soundstage of the Sony MDR-MV1 is a little bit more big and open than a traditional studio headphone, and larger than the HD600”
Audio Discourse (Antdroid)
Intimate and forward — precise, but not a wide stage.46%
“The Sony MDR-MV1 is less concerned with producing a vast and dramatic stage than it is with performing fast, accurate, and fluid imaging.”
Major HiFi
Consistently praised and central to the immersive-mixing pitch. Reviewers repeatedly call the imaging precise, accurate and fast, with clean instrument placement and strong localisation of objects in a surround field — the one 'technical' area almost nobody argues about, even among those who find the stage small.
“solid and realistic detail retrieval, accurate imaging, and an adequately fast performance.”
Major HiFi
“the localization of sound sources works very well, and the headphones also represent binaural signals very well.”
proaudio.tech (Peter Kaminski)
Measured
The high-end lift aids placement — Sound On Sound found “the extra high‑end detail made it easier to localise objects within the 360‑degree panorama,” which is exactly the use case Sony designed the MV1 around.
Generally rated resolving and clean, helped along by the treble lift, and strong for a headphone at this price. A minority hears the driver as slightly soft or slow — competent rather than class-leading on micro-detail — but most reviewers describe it as detailed and revealing.
“They’re incredibly detailed and rated by the manufacturer as flat from 5 Hz to 80 kHz.”
Tape Op
“I find the detail retrieval “soft” for my liking. Like the driver response is a tiny bit slow”
r/headphones (RATKNUKKL)
Measured
proaudio.tech attributes the clean transients to a quick driver — “the driver has a correspondingly short response time” — while noting “the transients are not overemphasized either,” i.e. detailed without being etched.
Composed rather than explosive. The elevated bass gives it more low-end weight and drive than most open-backs, and reviewers describe controlled, confident punch; but it's tuned for accuracy, not physical slam, and a few hear the driver as a touch soft. Clean and steady at sensible volumes.
“The Sony MV1 launches off the line with torque that feels unexpected for an open back.”
r/headphones (mournfulmonk)
“the transients are not overemphasized either”
proaudio.tech (Peter Kaminski)
Measured
The 40 mm driver is easy to drive (24 Ω, 100 dB/mW) and measures with a quick response time; the sense of 'punch' comes from the elevated low end rather than from unusual macro-dynamic swing.
Comfort
Strong consensus · 9 srcThe most unanimous positive. At roughly 223 g it's among the lightest studio over-ears made, with soft suede/Alcantara pads and a very low clamp — reviewers repeatedly say it nearly disappears on the head and stays comfortable for hours, even with glasses. The only caveats are a possible pressure point on top of the head for some, and snug cups for large ears.
“I don't think I can ever recall testing a pair of headphones that sat so lightly on the head.”
Sound On Sound (Sam Inglis)
“one of the most comfortable headphones I’ve ever had on my head, and I was able to wear it for hours on end without a trace of fatigue”
Audio Discourse (Antdroid)
Measured
About 223 g — Sonarworks calls it “the second lightest studio over-ear open-backs that we've encountered.” Soft suede/Alcantara pads and low clamp; the main fit caveats are a top-of-head pressure point for some heads (Sonarworks) and tight cups for large ears — Major HiFi warns “those with larger ears might run into some issues here.”
Light aluminium earcups on plastic yokes, with a detachable cable — and it divides reviewers. Some find the look and feel cheap for a $400 headphone (a couple even mistook the metal for plastic at first); others call it solid, durable and easy to repair. Recurring practical gripes: no case in the box, and a proprietary threaded cable that's hard to replace.
“Though plastic construction can sometimes give the impression that the headphones are cheap, the Sony MDR-MV1 are anything but.”
SoundGuys (Christian Thomas)
“I think this look and build betrays their price point”
Major HiFi
Measured
Aluminium perforated cups + plastic yokes at ~223 g; no case is included, and SoundGuys flags the cable's proprietary threaded end — “the only replacements you can get are from Sony themselves or certified resellers.” Sonarworks rates the durability highly despite the weight.
Isolation
Strong consensus · 5 srcOpen-back by design, so there's effectively none: it leaks freely both ways and blocks almost nothing. Expected for the type and irrelevant to its studio purpose, but it pins the MV1 to quiet rooms and solo listening — not shared offices, tracking near a mic, or noisy commutes.
“the Sony MDR-MV1 will not isolate you from your surroundings, and only block about half of high-frequency noise.”
SoundGuys (Christian Thomas)
Measured
Fully open-back: SoundGuys measures it blocking only about half of high-frequency noise and nothing lower, with free leakage both ways — a quiet-room / studio-monitoring headphone, not one for shared or noisy spaces.
The price is where opinion splits hardest. At around $400 owners and some reviewers call it an underrated mid-price gem — a uniquely bassy, comfy open-back that's a steal when discounted or bought used near $300. Critics counter that at full retail it's outclassed by cheaper classics like the HD 600 and HiFiMan Sundara. The verdict tracks the price you actually pay.
Measured
Street price roughly $350–$400 (MSRP $419.99; frequently seen nearer $338; used ~$280–$350). The value case swings on the price paid — a clear win around $300, more debated at full retail against the Sennheiser HD 600 and HiFiMan Sundara.
Where it splits
Underrated — a strong deal, especially discounted or for immersive mixing.55%
“a worthy contender in the hotly contested mid-priced tier of reference headphones.”
