Bowers & Wilkins Px7 S3

Measured

RTINGS reads Sound Signature “Boosted Bass”, Bass “Very Emphasized (7 dB)” and Treble “Slightly Underemphasized (-3 dB)”. Three squig rigs agree on the shape: Kuulokenurkka puts 60–200 Hz +7 to +8 dB above Harman 2018 (+8.5 dB over its own HD 600), GadgetryTech +5 dB with ANC on and +7 dB off, DHRME +7 dB over its HD 600 — each with a presence dip around 3–6 kHz and a rebound above 6 kHz. Les Numériques' lab describes the same thing in words: bass and treble both too pronounced, the result “objectivement loin d’être un modèle de transparence”. RecordingNOW calls them “the most V-shaped” of B&W's current range.

vs. listeners — Both camps can be honest. SoundGuys found that “the main culprit behind divergent ranges of emphasis is the decision to put the drivers of the headphones in the lower part of the ear cup” and warned that outlets would disagree; RTINGS says the response “can yield a different sound between wears”. Kuulokenurkka's four seatings of one sample move the 3–6 kHz band from −0.3 to −6 dB against target, and two rigs even disagree on whether it is bassier than the Sony WH-1000XM6. A reviewer whose pair seals and seats one way hears balance; a rig, or an owner seated another way, gets the shelf.

Measured

Every rig measures a large shelf: RTINGS “Very Emphasized (7 dB)”, the squig rigs +5 to +8.5 dB at 60–200 Hz, and Les Numériques bass “particulièrement gonflés jusqu’à 100 Hz”. Loud and Wireless hears it as “tightly controlled, which improves the clarity and separation of the mids”, and Tom's Guide argues the difference is definition, not quantity: “There’s more definition to notes, and more space for the rest of the music to breathe.” AVForums concedes that on the heaviest material “it can sound a little overblown”, and Wired liked it but notes “Bass is rich, pointed, and ramped up, so that I preferred to EQ it down a couple notches.”

vs. listeners — A measured +7 dB shelf is not in doubt; the camps disagree about what it does to the music. Volume and seal are the likely variables — SoundGuys notes it listens below its measurement level and that its impressions did not always match its data, and a firmer seal adds bass on every rig that published ANC-on and ANC-off files.

Measured

Kuulokenurkka and DHRME both put 3–6 kHz about 5–6 dB below their own HD 600 and 6–10 kHz 2.5–4 dB above it; GadgetryTech shows the same dip (−5.7 dB vs Harman) and rebound (+2.1 dB). SoundGuys hears the consequence: “The odd treble can sometimes lead to strangely shrill sibilants and fricatives in vocal-focused content if it’s loud enough.” Les Numériques' verdict is that “son aigu très prononcé restera inévitablement clivant”, and Kuulokenurkka reports “bright uneven treble, which sometimes almost makes my ears bleed.” Owners on r/headphones and Head-Fi report the same sibilance.

vs. listeners — Average level and evenness are different properties: RTINGS scores the treble slightly under target on average and still lists the peaks as a headline con, and Fnac's lab even hears “des aigus un peu aux oubliettes”. Which listener gets the relaxed reading and which gets the sharp one depends partly on seating — Kuulokenurkka's positions move the presence band by nearly 6 dB — and partly on source: T3 found “Poor sources can make that sibilant, though”.

Measured

Les Numériques places the scoop between 300 Hz and 1 kHz. Kuulokenurkka, measuring one sample at four seatings, found that “upper mids can be almost anything when you move the headphones by few millimeters.” Tom's Guide, from the other camp, still noted “There’s perhaps some dip in the lower mids, but you’d be hard pressed to notice it in most listening.” RecordingNOW: “I find the mids to be a bit lacking for my tastes, they’re a bit recessed and lacking body”. SoundGuys: “there are a few times where you might notice male vocals struggling against bass guitars and drums”.

Measured

SoundGuys measures the ANC “Reducing perceived loudness of all samples by an average of 83-84%”. Les Numériques finds the ANC acting only below about 800 Hz (more than 25 dB at 200 Hz) and that “les fréquences comprises entre 400 Hz et 2,5 kHz ne sont pas suffisamment atténuées pour occulter les conversations environnantes soutenues”. Fnac's lab scores isolation 5.9/10 and says low frequencies are poorly covered. Loud and Wireless's bench reads the opposite in the upper range — “it’s better than all the others at muffling the upper mids to high frequencies!” — while conceding AirPods Max was quieter on a plane. RTINGS: “Sony and Bose blow the Px7 S3 out of the water when it comes to overall ANC performance”.

vs. listeners — The benches disagree on which band leaks — Les Numériques says voices (400 Hz–2.5 kHz), Fnac says bass, Loud and Wireless says the upper range is the strongest in its group — so the camps track what each tester's environment threw at it. Seal matters too: SoundGuys credits much of its result to “a very easy-to-achieve seal”, and glasses or an awkward seating weaken it. Owners split cleanly between “I was expecting a non-existing ANC, but to my surprise it’s actually fantastic” and Sony owners who found it barely touched background hum. Every source that tested outdoors names wind as the weak point.

Measured

300 g by B&W's spec; RecordingNOW weighed 298.3 g, Fnac 298 g and Les Numériques 297 g — about 45 g heavier than the Sony WH-1000XM6 and Bose QC Ultra, well under the AirPods Max. Wired found the clamp eased with wear; owners on r/BowersWilkins report the same after a few weeks stretched over books. Future Audiophile: “Over time, the inside of the ear cups got physically hot on long trips.” T3: “I have found the earcups' positioning in relation to my ear canals can move and therefore require some adjusting.” headphonecheck: “My glasses slipped easily between pad and temple without noticeably affecting passive isolation.”

Measured

SoundGuys singles out repairability — “you can not only remove the earpads but also replace the headband padding as well” — though the battery is not user-replaceable (headphonecheck says service centres can swap it). Amazon's topic tally shows build 20 positive / 0 negative, but connectivity 13/13 and Bluetooth connectivity 10/11: connection drops, multipoint hiccups and an over-eager wear sensor recur in 1–3★ bodies, Les Numériques found the sensor “capricieux”, and owners on r/BowersWilkins fixed pausing by lowering its sensitivity.

Measured

No lab test isolates resolution. SoundGuys' caveat: “even though the emphasis in the upper octaves can offer the illusion of “detail.”” Fnac's lab scores distortion 8.5/10. RecordingNOW, despite rating it the best-sounding headphone under $600, describes the stock tuning as “very detailed but “relaxed” in a way.”

Measured

SoundGuys' MDAQS run singles out “the ultra-high immersiveness score”, and Les Numériques lists a “Scène sonore profonde et immersive” among its strengths. What Hi-Fi? frames it the other way: “The Sony WH-1000XM5 will grant a more open presentation, but the B&W have an intimate character that puts you in the eye of the musical storm no matter what you choose to feed them.”

Measured

Kuulokenurkka's second sample measures the left channel 1.7–2.1 dB hotter at 2 kHz in three of four seatings and 4.2 dB hotter at 3 kHz in one; GadgetryTech's five-seat average shows 2.5 dB (ANC on) to 4.5 dB (ANC off) between channels at 2 kHz. Both rigs hold their reference headphones within about a decibel. RTINGS, in its Px8 comparison, credits the Px8 with “a slightly more even response with better stereo matching”. Audioholics, from the majority camp: “Px7 S3 makes up for the closed-back soundstage in imaging precision and detail.”

Measured

Each driver has its own amplifier; Loud and Wireless found them “easily the loudest headphones in this group”. Head-Fi's bizkid reports “almost DT1770mkII levels of slam”, while RecordingNOW found the stock sound “a bit flat and un-engaging” before its EQ.

Measured

B&W's US store lists $479 (In Stock); Amazon, Sweetwater and Crutchfield sell it at $429, and it launched at $449. UK RRP £399 with Amazon UK at £266.88; French retailers €350–460. Engadget notes there is no automatic pause on speech, no location-based profiles and no assistant voice detection. Fnac's lab tied its value doubt to isolation (“pas à 429€”). Amazon's value tally runs 30 positive / 9 negative.
