Detailed Comparison
Sound Quality
Sony WH-1000XM4
A judicious, confident sound with LDAC hi-res, DSEE Extreme upscaling and 360 Reality Audio support — widely praised, with the main critique being a slightly bright top end that some EQ to taste.
As far as sound goes the XM4 needs very few excuses made for it — a confident top end and a judicious overall balance.
Updating the QN1 chip algorithm and improving digital sound processing elevates the XM4 from great to superb over the XM3.
40mm drivers deliver rich, not overly bass-heavy sound; bass lovers can add thump easily in the app EQ.
Supports LDAC and 360 Reality Audio; DSEE Extreme upscaling exists but the difference on/off can be hard to hear.

Mediocre microphone/call quality — barely better than the XM3 and frustrating for conference calls
Multipoint disables LDAC — you can't have two-device pairing and hi-res audio at once
No aptX and no IP water/sweat rating; not recommended for running or heavy gym use
Some long-term units develop a piercing feedback noise in one cup in ANC mode (moisture/sweat on the mics over years)
Sony doesn't sell official replacement ear cushions, a wear-and-tear item on a long-lived product
Sony WH-1000XM6
What Reviewers Agree On
Class-leading, natural-sounding active noise cancellation — a faster QN3 processor and 12 microphones widen the lead over the XM5 and most rivals
The foldable design is back — earcups fold and swivel into a smaller, zipper-free case, undoing the XM5's biggest travel regret
Genuinely comfortable for long sessions with a light, ~252g build and low-fatigue clamping force
Warmer, more controlled sound than the XM5 with a deep 10-band EQ and LDAC/LC3 hi-res support
Excellent everyday feature set — reliable multipoint, wear detection, Speak-to-Chat, Auracast/LE Audio and a fast 3-minutes-for-3-hours quick charge
USB-C audio and listening-while-charging are finally supported, alongside a retained 3.5mm jack for passive wired use
Deal Breakers
Build feels plasticky and prone to scuffs/stains for a $450 flagship, echoing long-running Sony build-quality complaints
Battery is only competitive at 30 hours ANC-on (40 off) — well behind the 50-60 hours of Sennheiser and JBL rivals
Touch controls remain for playback and volume, which several reviewers find imprecise or unwanted
Not the best-sounding can in its class — a sharp ~10 kHz treble peak the 10-band EQ can't fully tame draws audiophile criticism

Not the best-sounding can in its class — a sharp ~10 kHz treble peak the 10-band EQ can't fully tame draws audiophile criticism
Reddit owners' take: not 'the best' at any one thing, but it does everything right and sounds more than good enough once EQ'd.
Versus the XM5: the XM4 is brighter with more vocal 'bite/sizzle', while the XM5 is warmer with more sustained bass — and the XM4 can get a touch boomy at 100-200Hz.
Sony WH-1000XM6
New 30mm drivers deliver a warmer, more controlled, slightly bass-forward Sony tuning that most reviewers call the best the XM line has produced — though it takes EQ to shine, and audiophile-leaning critics flag a sharp ~10 kHz treble peak the deep 10-band EQ still can't fully fix.
All-new drivers versus the last generation deliver excellent, wide-range sound — the low end is much stronger, especially sub-bass, addressing the XM5's spiky midrange and weaker bass.
Out of all the XM models tested (XM2 through XM4), the XM6 is the best-sounding out of the box, takes EQ very well, and stays crisp and detailed rather than muddy.
Sony's new 30mm driver with a more rigid dome and perforated voice-coil bobbin, tuned by mastering engineers, gives richer detail and clearer vocals — though shrinking from 40mm trims some warmth and bass presence for a more refined balance.
You still get the familiar Sony tuning — slightly warm and slightly bass-forward — but it's more controlled this time round.
Despite what most reviewers say, this isn't the best-sounding headphone in its price category — the sound is fundamentally midbass plus a mountain of 10 kHz, and even after EQ that sharp 10 kHz peak can't be fixed without a band right at 10 kHz.
The XM line has long been among the worst-sounding ANC headphones to audiophile ears; the XM6 improves but the 10,000 Hz region still runs high and can sound sharp and grating, so it isn't the best-sounding can in its class.
Sony went deep on EQ — a 10-band equalizer (octaves from 32 Hz to 16 kHz) replaces the old 5-band, and it makes a big practical difference for dialling the sound to taste.
Reddit owners are split on the tuning — some find the bass prominent and the soundstage underwhelming, while others say it clearly beats the XM5, making it the best XM yet.
It's still not flat or neutral and shouldn't be — these are tuned for fun listening rather than studio use, with sound described by one owner as 'like being at a live event'.
Noise Cancellation
Sony WH-1000XM4
The XM4's headline strength: industry-leading ANC at launch via the QN1 chip and dual mics per cup, with smart adaptive behaviour. It still tunes out office and travel noise as well as almost anything in its price class.
Sony's QN1 processor with two mics on each earcup delivers what Sony billed as its best-ever noise-cancelling, automatically optimising for ambient conditions.
Outstanding noise isolation thanks to the ANC plus a comfortable, premium design — still worth checking out even after the XM5 replaced it.
Adaptive Sound Control senses whether you're sitting, walking, running or in transit and adjusts ANC to the activity automatically.
For an 8-10 hour office day the ANC reliably tunes out talking and loud noise — a standout for work environments.
The AirPods Max slightly edge the XM4 on raw noise-cancelling, but the XM4 is lighter, has a far better case and is $200 cheaper.
Long-term flaw: some units develop a loud, piercing feedback noise in one cup only in ANC mode (suspected sweat/moisture on the internal mics over years).
Sony WH-1000XM6
The XM6's headline strength: a QN3 processor seven times faster than the XM5's chip, 12 microphones and AI trained on 500 million voice samples. Reviewers near-unanimously call it the best, most natural ANC on the market, with measurements showing it edging Bose — though it remains a close fight with the AirPods Max 2.
The XM6 packs 12 microphones (up from 8) and a far more powerful QN3 chip, and Sony trained the headphones on 500 million voice samples to better separate human voices from environmental noise.
The new QN3 processor is seven times faster than the XM5's chip, and that unlocks a new level of noise cancellation.
In measured testing the XM6 blocked up to 43.9 dB versus 41.4 dB on the Bose QC Ultra in a silent environment — a measurable real-world ANC win.
The XM6 offers class-leading noise cancelling, and the adaptive two-stage ANC now activates in roughly 0.5 seconds versus about 3 seconds on the XM5.
RTINGS rates the XM6's noise cancelling best-in-class, with a microphone system that separates speech from background noise more effectively than rivals.
Comfort & Design
Sony WH-1000XM4
The XM4 keeps the XM3's understated, lightweight design and superb comfort for long sessions, folds for travel and ships with an excellent hard case — the build holds up for years, with warm ears the only common gripe.
Design tweaks make the XM4 look slightly more lux and even more comfortable to wear for long stretches than the XM3.
Comfortable enough for full workdays — barely noticeable where other headphones bother the ears after 20 minutes.
After a year of heavy use the wear-and-tear is essentially non-existent and they don't wear you out — superb value.
Lighter than the AirPods Max with a much better hard carrying case; folds flat for travel (the XM5 does not).
Like most over-ears in this class the faux-leather pads aren't very breathable — ears get warm after about 6 hours.
At ~254g it weighs 1g less than the XM3, with the same two colourways and a build that stays creak- and rattle-free for years.
Sony WH-1000XM6
The big design news is the return of the folding hinge — earcups fold and swivel into a smaller, zipper-free case. At ~252g the XM6 is among the lightest flagships and most reviewers find it comfortable for long days, but the plasticky, scuff-prone build draws repeated criticism at $450 and a minority report lingering clamp pressure.
The earcups fold up again, with a new significantly smaller case that fits cables and no longer uses a zipper — putting the XM6 back near the top of travel-ready noise-cancelling headphones.
Sony heard the complaints and made the XM6 fold and swivel so it rests neatly on your head and packs down for travel — the case shaves roughly 30% off the previous model's bulk.
Among flagship headphones the XM6 is one of the lightest tested at 252.8g, versus 262.2g for the Bose QC Ultra 2 and far lighter than the AirPods Max.
The clamp force is light enough not to be fatiguing yet firm enough to keep the ANC seal intact — Bose still edges it slightly on comfort, but Sony is not far behind.
For a flagship $450 headphone the materials and build quality feel on the cheaper side, with a lot of high-frequency creak from handling the plastic.
Battery & Charging
Sony WH-1000XM4
30 hours with ANC on (≈38 with it off), a 10-minute quick charge for ~5 hours, and ~3 hours for a full charge. Real-world tests confirm the rating; after ~3 years it settles to roughly 24 hours.
Rated up to 30 hours with ANC on; a 10-minute quick charge gives up to 5 hours of playback.
Real-time test averaged ~31 hours with ANC on — right in line with the 30-hour claim.
Confirmed over 8-9 months of use: ~38 hours ANC off and a true ~30 hours ANC on.
Full 0-100% charge takes roughly 3 hours; one tester filled them in ~20 minutes from dead on a high-watt charger.
After 3 years, continuous-listening battery dropped from ~38 hours out of the box to ~24 hours — still plenty for most.
In practice you rarely check the battery — a weekly 5-10 minute top-up keeps them going thanks to the long life and quick charge.
Sony WH-1000XM6
Rated 30 hours with ANC on and 40 with it off — RTINGS measured just over 31 hours ANC-on, so the rating holds. A 3-minute charge returns 3 hours of playback and a full charge takes about 3-3.5 hours. The catch: 30 hours is merely competitive when Sennheiser and JBL rivals push 50-60.
Rated up to 30 hours of playback with ANC on and up to 40 hours with it off — unchanged from the XM5.
RTINGS measured over 31 hours of continuous playback with ANC on — north of Sony's advertised 30 hours, so you're covered for long-haul flights.
A 3-minute quick charge with a USB-PD charger returns about 3 hours of playback, and a full 0-100% charge takes roughly 2.5-3.5 hours depending on the charger.
Unlike the XM5, you can now listen over USB-C while charging — and the 3.5mm jack remains for passive wired listening.
Battery is starting to lag the competition — 30 hours ANC-on is far from the best result from over-ear cans, with the JBL Live 770NC claiming 50 hours and the Sennheiser Momentum 4 around 60.
Call Quality & Mics
Sony WH-1000XM4
The XM4's enduring weak spot. Microphone/call quality barely improved over the XM3 and is the most consistent criticism — fine for casual calls, frustrating for conference calls.
Mic-quality test: the XM4 didn't do much better than the XM3 — it doesn't justify an upgrade on microphone quality alone.
Owner reports call quality is poor for conference calls — crackling and audio dropouts.
Frequent complaint: the microphones are the one area people consistently call terrible on these otherwise excellent headphones.
Speak-to-Chat / Quick Attention help during conversations, but many users just lift a cup or remove the headphones rather than rely on the mics.
Despite the quirky mic issues, the balanced audio and strong ANC still make them worth getting if you mostly consume media rather than take calls.
Sony WH-1000XM6
Call quality is the area Sony worked hardest on — 12 microphones, bone-conduction sensing and AI voice training noticeably improve pickup over previous XM models. Reviewers find it clearly better than before, though a minority and long-time Reddit users still rate Apple's mics ahead for calls.
The microphones are definitely better than before — call quality is impressive enough that the reviewer expects buyers to be 'floored' by it.
Four additional microphones over the XM5 plus AI voice processing meaningfully enhance call quality in the XM6.
The XM6 also uses bone conduction to help isolate your voice, and in a quiet environment the microphone performance is very good with minimal sound leakage.
Despite Sony's bone-conduction system, one 30-day tester still felt the AirPods' microphones were better for phone calls.
App, Features & Connectivity
Sony WH-1000XM4
Speak-to-Chat, wear detection, multipoint and a deep companion app are the XM4's smart-feature wins — the catches are that multipoint disables LDAC, aptX was dropped, and the app/firmware can occasionally annoy.
New over the XM3: multipoint Bluetooth (two devices at once) and a proximity sensor for wear-detection auto-pause/resume.
Multipoint works perfectly switching between iPhone, Mac and iPad — a genuinely seamless everyday convenience.
Speak-to-Chat auto-pauses music when you talk, with a configurable 15/30/60-second resume — clever, though some find it triggers too easily and switch it off.
Bluetooth 5.0 with SBC/AAC/LDAC; aptX was dropped versus the XM3, and a 3.5mm jack plus USB-C are included.
Headphones still receive over-the-air updates that have improved the noise-cancelling tech over time.
The app/firmware can occasionally annoy — failed firmware-update prompts and reconnection fiddling were reported.
Sony WH-1000XM6
The Sony Sound Connect app is deep — 10-band EQ, Speak-to-Chat, head-gesture controls, adaptive sound and a background-music ambient mode. Multipoint is reliable, and firmware updates have added Auracast/LE Audio, head tracking and Gemini Live. Two physical buttons stay, but the touch panel still handles playback and volume — a divisive choice.
A background-music mode makes audio sound like it's coming from tinny speakers about 20 feet away, as if you're in a cafe — a distinctive ambient listening option.
A firmware update added Bluetooth LE Audio / Auracast support, letting you share audio with another pair of headphones or broadcast to a group.
Sony has rolled out a firmware update bringing Gemini Live AI assistance and audio sharing through Fast Pair to the XM6.
A later firmware update added head tracking over a Bluetooth LE Audio connection, improving the headphones' behaviour with Samsung phones.
Multipoint works well — the XM6 pairs with two Bluetooth devices at once and switches automatically when a call comes in or playback starts on either device.
Value vs Competition
Sony WH-1000XM4
Launched at $349 alongside the XM3's price, the XM4 is now routinely $198-260 — making it, years on, one of the best-value premium ANC headphones and a frequent pick over the pricier XM5.
Launched at the same $349 price as the XM3 did — and is now frequently discounted well below that.
Among the most popular and well-regarded wireless headphones you can buy; the XM5 is a premium upgrade at a more premium price.
Even 5+ years on, with a ~$250 price gap to the XM6 and street prices under $200, the XM4 remains excellent value and many prefer it to the XM5.
Now around $250 new / ~$200 used — more affordable than ever and a fantastic option, especially refurbished.
The staple recommendation for the average buyer — still ~$50 cheaper than the XM5 and they fold, which the XM5 doesn't.
If you just want a solid, great-sounding pair of ANC headphones and don't need the newest features, the 2-3-year-old XM4 is still brilliant today.
Sony WH-1000XM6
At a $450 launch price the XM6 is expensive, and the still-available XM5 (now ~$350) and discounted XM4 undercut it. But against the AirPods Max 2, Bose QC Ultra 2 and Sennheiser Momentum 4, most reviewers conclude the XM6's all-round polish — ANC, comfort, features, folding design — justifies the price, and Amazon discounts have already pulled it below the XM5's launch price.
At $450 the XM6 is really expensive, but the whole premium ANC category is full of rivals that try to beat it and don't — which makes it still feel like the one to get if you want the flat-out best travel and work headphones.
The WH-1000XM6 is an improvement over the XM5, but the older model is still sold and arguably offers more value for buyers who don't want to pay the higher price.
Factoring in best-in-class ANC, the XM6 is priced fairly — the only headphone that clearly beats its noise cancelling, the AirPods Max 2, costs more.
Against the Bose QC Ultra 2 the call is close, but for travellers, open-office workers and long commutes the XM6 wins on stronger ANC and longer battery, while Bose keeps the comfort edge.
On a real-world flight the XM6 blocked out a crying baby six rows back for an entire five-hour flight — a standout travel-ANC result.
Sony went through certifications and tests specifically so it could legally market the XM6 as having the best active noise cancellation.
It's one of, if not the best ANC headphone tested — with some of the best passive isolation in the business too — though it sits 'second in pack' on each measure rather than dominating both.
Some travellers note that on an airplane with vibrations, the vibration can transfer into the cup with the ANC engaged and become annoying — a real-world caveat.
The scratch-prone finish and easily-dirtied earcups are legitimate concerns on a $450 product — marks and a little staining build up after just a bit of use.
Headphonesty reports that, based on user feedback, Sony's newest $450 headphones are being criticised for the same build-quality issues that plagued the fragile-hinged XM5.
The faux-leather earpad and headband material isn't very breathable, so ears can feel hot after about an hour compared with mesh-padded rivals.
A dissenting comfort take: the clamping force is real and these become painful to wear after more than about 15 minutes for some heads.
iFixit found the XM6 a real step forward for repairability — screws replace glue for the battery, and the drivers and ports are modular and accessible.
SoundGuys' verdict is that the XM6 has decent battery life but not the best in the category.
Using LDAC takes an extra toll on endurance — battery drops from about 30 hours to roughly 26 hours with ANC and LDAC both on.
Charging stops at approximately 80% by default to reduce long-term battery wear, with battery-care options in the app.
A long-running Reddit gripe: call quality on Sony headphones has been weak for years — though several owners say the XM6 is a clear step up.
You can double-tap the noise-cancelling/ambient button on the headphones to quickly mute and unmute yourself on a call.
The XM6 supports LDAC up to 96 kHz / 24-bit and adds LC3 codec support along with the newer Bluetooth LE Audio stack.
You still get only two physical buttons (power and noise-cancelling), so playback and volume rely on touch controls — which several reviewers dislike, even if they work reasonably well here.
Sony is one of the few makers still putting a 3.5mm headphone jack on a top-end model, with a wired audio cable included in the box.
Lossless audio is supported only through the 3.5mm stereo cable, not over USB-C — the USB-C port is for charging and data, not audio playback for some setups.
Reddit owners report the wireless experience on PC can still be poor, with audio stutter tied to Bluetooth-stack quirks rather than the headphones themselves.
Sony WH-1000XM6 prices have already dropped on Amazon to below the previous generation's launch price, easing the value concern at full MSRP.
Sony's $649 1000X The ColleXion is a luxury, design-led variant priced well above the standard flagship — and isn't necessarily better than the WH-1000XM6 in every way.
TechRadar's verdict: excellent headphones that meld the best parts of Sony's previous cans — among the best you can buy.
