By aspect — in detail
Sources agree on the SHAPE and split on the verdict. The stock tuning is a warm, bass-forward 'Sony house sound' — boosted lows, a recessed/dipped midrange, and a treble that rolls off up top. Most enthusiast and critical reviewers hear that as muddy, dark or 'veiled' and reach for EQ; consumer-focused reviewers and many owners hear it as pleasant, warm and fun. The measurements show the warm, U-shaped tilt clearly, so the disagreement is really about how that response lands.
Measured
Measures as a warm, U/V-shaped tilt: a generous bass shelf under ~150 Hz, a subdued/dipped midrange (SoundGuys puts the dip roughly 300 Hz–1 kHz on its B&K 5128 rig; TechGearLab's lab calls the overall response a U-shape, lows above target and mids/highs below), and a treble that rolls off steeply above ~10 kHz. The in-app EQ shifts the balance substantially.
⚠ vs. listeners — The warm, bass-forward, recessed-mid shape is literally what's measured, so 'muddy/dark' is an honest description of the stock tuning; 'pleasant/well-balanced' is the same response heard as consumer-friendly — and EQ closes much of the gap, which is why some camps describe it post-EQ.
Where it splits
Pleasant, warm and consumer-friendly — vibrant and easy to enjoy out of the box.38%
“well-balanced sound profile with rich lows, beautifully warm mids, and bright highs that maintain outstanding clarity across all volumes”
TechGearLab
Muddy / dark / 'veiled' out of the box — coloured and inaccurate; needs EQ to enjoy.62%
“that frequency response is pretty uneven as we go from 20 to 20 khz. There are lots of ups and downs along the way that lead to, again, a particular, somewhat veiled and somewhat inaccurate sound character, if you really want to get picky about it.”
Tom Martin (The Absolute Sound)
Everyone agrees the bass is boosted and reaches deep; they split on its quality. One camp hears it as punchy, fun and notably cleaner than the XM4's; the other hears it as simply too much — boomy and bleeding up into the lower midrange. The split tracks how bass-forward a listener likes things and whether they've trimmed the app's 'Clear Bass' slider.
Measured
A generous bass shelf under ~150 Hz (Chrono) that settles late around 250 Hz, causing upper-bass bleed into the lower mids; SoundGuys measures it as elevated 'to the detriment of the midrange' and suggests dropping the app's 'Clear Bass' a couple of notches. Sub-bass extension is good.
Where it splits
Punchy, deep and cleaner/tighter than the XM4 — emphasised but enjoyable.42%
“the XM5's bass shelf seems to be a lot more uniform and therefore quite a bit cleaner sounding, without having as much of the overbearing swell that the XM4's bass had”
Chrono (headphones.com)
Boosted too much — boomy, and it bleeds into and masks the midrange.58%
“the Sony WH-1000XM5 boosts bass probably a little too much, and definitely to the detriment of the midrange.”
SoundGuys
The dominant view is that the midrange is recessed — drowned out by the boosted bass and treble, with vocals and instruments set back (the measurements show a real dip). A minority hear the high-mids as forward and clear. EQ pulls the mids back up for many listeners.
Measured
A measured upper-bass-into-lower-mid bleed plus a subdued ~300 Hz–1 kHz region (SoundGuys); TAS and Soundphile both note an upper-midrange dip. The recessed-mid camp is the larger one and is backed by the graph; the 'forward mids' read is the outlier.
Where it splits
Recessed / buried — vocals and instruments get dulled, especially without EQ.84%
“The comparatively subdued midrange (from 300Hz to around 1050Hz) might sound a bit off as it gets drowned out by the much louder highs and lows.”
SoundGuys
Forward and clear — the high-mids especially are expressive for vocals.16%
“They sound forward, with significant textural differentiation, sparkling clarity, and great expressiveness for vocals”
TechGearLab
Genuinely split, and both camps describe the same uneven response. One side hears the top end as dark and rolled-off — short on air above ~10 kHz; the other hears the lower-treble/presence region as over-emphasised, so cymbals, hi-hats and snares stand out and can turn sharp when pushed.
Measured
There's a steep roll-off after ~10 kHz (SoundGuys, Chrono, HeadphonesAddict), so the very top loses air; Chrono notes only a slight 2–3 dB lower-treble bump around 6 kHz, far tamer than the XM4's hot peak. SoundGuys measures the presence region above its target curve.
⚠ vs. listeners — Both reads are right about different parts of one curve: the upper treble genuinely rolls off (so 'dark/no air'), while the lower-treble/presence region sits above target relative to the recessed mids, which makes cymbals and snares jump out and read 'bright' or sharp.
Where it splits· split roughly even
Dark and rolled-off up top — muted, lacking air and sparkle.
“the upper treble is quite dark and feels muted, with a rather steep roll-off in the frequencies above 9-10Khz”
Chrono (headphones.com)
Over-emphasised / bright — cymbals, hi-hats and snares pop and can sound sharp.
“On the other end of the frequency range are the highs — and those, too, are a little over-emphasized compared to our target curve.”
SoundGuys
Most reviewers hear a narrow, intimate, 'in-your-head' presentation typical of a closed ANC headphone — and several call it a real weakness against rivals. A minority (notably a lab-based editorial test) hear it as wide and spacious.
Measured
Closed-back; the narrow read is the consensus, with RecordingNow calling the music 'pretty 2D and flat' against the Bose QuietComfort Ultra and Sennheiser Momentum 4. TechGearLab's high expert soundstage score is the clear outlier.
Where it splits
Narrow / intimate / '2D' — closed-in and short on width and depth.79%
“Soundstage is limited in both width and depth and never gets past the “you’re wearing headphones” kind of presentation”
Soundphile Review
Wide and spacious — room for instruments to breathe.21%
“The soundstage on the XM5 is incredibly wide, allowing listeners to hear fine details”
TechGearLab
Seen as decent-to-accurate for placement — center and left/right are well defined — but hemmed in by the narrow soundstage and limited instrument separation in busy tracks.
“the imaging is almost spot on. There are some minuscule blurry spots, but nothing that would throw you out of enjoying your music.”
HeadphonesAddict
“it only covers 90 degrees – 45 degrees from the centre – so instruments rarely sound like they’re coming from the sides”
Soundphile Review
Broadly judged unremarkable for the price. Reviewers agree it isn't a resolving headphone — complex tracks get muddled or smeared and separation is limited — though several note that's fine for the casual, background and commute listening it's built for.
“But I don’t hear them as a highly resolving headphone. Which makes sense in the context of the warm and soft, background music idea.”
Tom Martin (The Absolute Sound)
“this just isn’t a headphone with a lot of “nuance” and micro-details for critical listening”
RecordingNow
Measured
Chrono found no resolution gain over the XM4 despite the new driver; Soundphile hears detail as 'smeared' and separation as 'barely sufficient.' Adequate for background use, short of its price for critical listening.
Lightly covered and mixed. Described as polite and soft by design — not very punchy or slam-focused out of the box (which suits relaxed listening) — with fast transient attack but a longish decay. EQ adds some snap.
“The 1000XM5’s warm and soft profile works very well there because it’s not too dynamic, it’s not too punchy, it doesn’t surprise you or interrupt you.”
Tom Martin (The Absolute Sound)
“the Sony WH-1000XM5 aren’t made for speed. Drum kicks don’t feel as tactile, so listening to double-pedal fast drumming can feel underwhelming.”
HeadphonesAddict
Isolation
Strong consensus10 srcThe headline strength and the clearest point of agreement: the active noise cancelling is class-leading — among the very best available — and especially strong on low-frequency rumble (planes, trains, engines). Passive isolation is solid too. The caveats are real but minor: a good seal matters (a poor fit undercuts it), rivals like the Bose QuietComfort Ultra and AirPods Max have since matched or beaten it in places, and the adaptive mode can briefly 'pump' outdoors.
“improves on the XM4's already-world-class implementation and delivers some of the very best performance I've heard in this regard--it easily matches what something like the Bose 700 can achieve”
Chrono (headphones.com)
“Canceling sounds in the range where most music is found by around 30dB, the headphones make engines, trains, and street noise drop off to about one-eighth of their original perceived loudness”
SoundGuys
Measured
Independent labs converge: TechGearLab measured ~31 dB total attenuation (by band roughly 19 dB low, 29 dB mid, 47 dB high); HeadphonesAddict measured ~29.5 dBA average reduction with ANC on and ~24 dBA of passive isolation; SoundGuys' B&K 5128 puts it around 30 dB across the core music band, with passive isolation taking over above ~500 Hz. A few owners with poor seals or weak units report much worse, and Soundphile notes 'this is not a surprising level of ANC any more' now rivals match it.
Light (~250 g) and comfortable for most heads, but with consistent caveats and a real dissenting camp. Nearly everyone agrees it's easy to wear and travel-friendly; a substantial minority find it runs hot, has thin/shallow pads, and fits awkwardly on smaller or narrower heads (where it can clamp oddly or slide).
Measured
Measured ~244–250 g with shallow earpads; Chrono notes the silicone/rubber-like pad material warms up and retains heat. Sweat build-up and a downward-pressing fit on small heads are the recurring comfort complaints; TechGearLab logged about 6 hours of comfortable wear.
Where it splits
Light and comfortable — easy for long, all-day sessions for most people.64%
“the XM5 remains one of the most comfortable wireless ANC headphones that I've tested thus far”
Chrono (headphones.com)
Runs hot, pads are thin, and the fit is awkward on smaller / narrower heads.36%
“those with narrower faces felt their ears ached and were squished after an hour”
TechGearLab
The most decision-relevant disagreement. Everyone agrees on the basics: it's all-plastic (the XM4's metal headband is gone), it no longer folds (so a bulkier case), and there's no water/IP rating. From there it splits hard — one camp finds it solid and premium-feeling for plastic; the other finds it cheap and fragile, with widely-reported cracked hinges and casing that peels near the hinges. Owner threads describe it as a unit lottery.
Measured
Fully plastic, including the headband (the XM4 used metal); ~244–250 g; no longer folds, so the case is taller; no IP/water rating. Cracked hinges and casing peeling near the hinges recur in long-term owner threads (RecordingNow notes broken-at-the-hinge units sold on eBay; an r/SonyHeadphones owner reports the material peeling near the hinges 'is going to happen eventually'). SoundGuys notes the later XM6 added a sturdier hinge and brought folding back.
Where it splits
Solid and well-made for plastic — feels reliable, won't break from everyday use.40%
“the XM5 still feels very solid for a headphone that's made primarily out of plastic, and I don't see these breaking down from regular, every-day usage.”
Chrono (headphones.com)
Cheap-feeling and fragile — all-plastic, no metal, hinges crack and the casing peels.60%
“Sony WH-1000XM5 come with a hard-shell carrying case, but are otherwise pretty fragile, with not metal parts. Even cheaper competitors have some metal for rigidity.”
HeadphonesAddict
Splits almost evenly, and it comes down to what you're buying it for. As an all-rounder — for best-in-class ANC, calls, battery and features — many reviewers call it an excellent buy. Judged on sound for the ~$400 launch price, others call it overpriced, pointing to cheaper rivals (and even Sony's own MDR-7506) that they prefer. Now that the XM6 has replaced it, the XM5 is widely discounted, which softens the value question.
Measured
Launched at ~$400; HeadphonesAddict calls that price 'absurdly high,' Soundphile suggests buying only below ~$300. With the WH-1000XM6 (2025) now the flagship, the XM5 sells discounted, and several reviewers say it's a good pick if you mainly care about noise cancelling.
Where it splits
An excellent all-rounder — worth it for the ANC, calls, battery and feature set.48%
“the Sony WH-1000XM5 is an excellent buy”
SoundGuys
Overpriced for the sound — cheaper headphones do better, you pay for ANC and branding.52%
“sonically there are many better headphones, including some at lower prices”
