Bowers & Wilkins Px7 S3 review: gorgeous over-ear ANC headphones with near-perfect sound

Bowers & Wilkins Px7 S3: two-minute review

The third version of Bowers & Wilkins’ Px7 wireless over-ear noise-cancellers is the most expensive yet. This money does buy a pair of extremely well-specified headphones, mind you – between Bluetooth 5.3 with aptX Lossless compatibility and multipoint connectivity, chunky battery life and a bespoke noise-cancellation platform, the S3 have it where it counts. And there’s more to come, in the form of spatial audio and Auracast compatibility, via promised upgrades. It also buys slightly less, in the physical sense. The profile of the S3 is a little more discreet than any previous Px7 model.

It also gets you absolutely impeccable build quality and standard of finish – there’s undeniable pride of ownership included as part of your outlay. Wearing them outdoors will reveal a little inefficiency where suppression of wind noise is concerned, but at least you won’t feel as self-conscious as you might have when wearing previous Px7 models.

The new active noise-cancellation platform works well, and it brings Bowers & Wilkins into line with the best noise-cancelling headphones that aren’t Bose. And where sound quality is concerned, this is now the best way to spend your cash. In every respect, the Px7 S3 impress. They’re detailed and dynamic, they’re open and spacious, they’re punchy and rhythmically adept – and best of all, they’re engaging and entertaining.

Circumstances a long way out of Bowers & Wilkins’ control means that a North American launch date, as well as a North American price, are yet to be confirmed. There are papers to be written about whether pricing Americans out of ownership of products like this is a good thing, and there are obviously ramifications for companies like Bowers & Wilkins when the North American market is so difficult to read. But for those of us living where the Px7 S3 are available and (relatively speaking) affordable, the news is uncomplicatedly good.

Bowers & Wilkins Px7 S3 review: Price and release date

• Release date: April 24th, 2025
• Price: $TBC / £399 / AU$699 (approx.)

The Px7 S3 launch at a very similar price (in the company’s native UK, at least, where tariffs aren’t quite such a thing as they are in some other territories) to 2023’s £379 Px7 S2e – so Bowers & Wilkins is to be congratulated for developing and releasing a new product without having to up the price all that much. At the time of writing, though, Bowers & Wilkins is still not certain of a launch date in North America, and still less of the price when that launch finally comes. This, apparently, is the sort of uncertainty that will make America great again.

The Px7 S3 nevertheless find themselves contesting the very upper end of the ‘premium/mainstream’ best wireless headphones market where the fearsome likes of Bose and Sony (to name just a couple of high-profile alternatives) roam. In other words, it’s going to take more than a premium logo and a premium price to make a success of the Px7 S3…

Bowers & Wilkins Px7 S3 review: Features

• Bluetooth 5.3 with aptX Adaptive and aptX Lossless codec compatibility
• Redesigned 40mm biocellulose drivers with discrete amplification
• 30 hours of battery life

When it comes to the most important stuff, Bowers & Wilkins has specified the Px7 S3 without apparent compromise. This may be a relatively expensive pair of headphones, but don’t doubt that it’s got it where it counts.

And while Bowers & Wilkins will tell you it’s concentrated its efforts on the physical design of the Px7 S3 and on upgrading the active noise-cancelling system, that doesn’t mean the driver arrangement hasn’t come in for attention. The company may, in public, declare itself very satisfied with the way the outgoing Px7 S2e sounded, but it’s made plenty of changes in an effort to liberate even better sound.

So while the 40mm biocellulose cones themselves are unchanged over the previous model, the Px7 S3 features a new chassis arrangement, new voice-coil, reworked suspension and upgraded magnet. The intention is to lower distortion and coloration yet further while offering superior dynamics. And for the first time in a pair of Bowers & Wilkins over-ear headphones, these drive units are powered by dedicated, discrete headphone amplification – improved sonic scale and energy is the idea.

Getting audio information to the drivers can be done in a couple of ways. As well as charging for the battery (which is, incidentally, good for 30 hours of playback with active noise-cancellation switched on and can turn 15 minutes of charging into seven hours of action), the USB-C slot can be used for data transfer. Connect it to the digital or analogue output of an appropriate source of music and 24bit/96kHz high-resolution content can be dealt with.

Multipoint wireless connectivity is handled by Bluetooth 5.3 and, as well as aptX Adaptive, the S3 are compatible with the aptX Lossless codec. This technology will automatically optimize transmission resolution, and will allow you to hear what that top-tier Presto, Qobuz or Tidal streaming service subscription is actually buying you (Qobuz and Tidal are both available for direct streaming in the Bowers & Wilkins ‘Music’ control app). The company also intends to make the Px7 S3 compatible with Bluetooth LE Audio (which includes the LC3 codec) and Auracast via a free firmware update ‘soon’. Support for spatial audio won’t be all that far behind.

As well as the ability to integrate (some of) the best streaming services around, the ‘Music’ control app also gives access to a five-band EQ with memory to save some settings, as well as presets including the company’s preferred ‘True Sound’ settings. It allows you to switch noise-cancelling on or off, engage ‘transparency’ mode, adjust wear-sensor sensitivity, check on battery status, and more besides.

Voice control is available via your source’s native assistant, and there are some physical buttons arranged on each earcup. On the right side there’s ‘volume up/down’ and ‘play/pause’ – these buttons have been reshaped to help with operation – and on the left there’s a ‘power on/off/Bluetooth pairing’ slider and a ‘quick action’ button. You can use the app to switch its function between ‘cycle through ANC options’ and ‘summon voice assistant’. Really, all that’s missing is a physical control for ‘skip forwards/backwards’.

Optimizing active noise-cancellation without impacting on the sonic performance of the headphones isn’t an easy trick, of course, but Bowers & Wilkins has given it a very thorough go. It’s developed a new ANC platform from scratch, and has deployed a total of eight mics to monitor the output of the drivers as well as outside noise in an effort to offer its best-ever ANC as well as outstanding call quality.

Bowers & Wilkins Px7 S3 review: Sound quality

• Wide open and yet tightly unified
• Great tonal balance
• Detailed and dynamic in equal measure

I may as well get right to it: the Bowers & Wilkins Px7 S3 are a great pair of headphones in purely sonic terms, and represent the very best way to spend £399 (or thereabouts, once worldwide pricing is sorted) if outright sound quality is the most important thing to you.

Tonally, they’re really nicely judged – even and pretty much neutral, with just the tiniest hint or warmth to prevent things sounding austere or chilly (unless you’re listening to something like Kraftwerk’s Trans-Europe Express, of course, which sounds just as draughty and frostbitten as is appropriate). The top end has bite that’s balanced against substance, and at the opposite end there’s weight and ample variation. In the midrange, the character and ability of singers as dissimilar as Mark E Smith and Aretha Franklin is made absolutely explicit. As well as the impeccable tonal balance, the Px7 S3 retrieve and contextualize a huge amount of fine detail, which contributes no end to the sensation of a complete and unexpurgated account of recordings.

Frequency response is equally convincing – there’s no suggestion of any area of the frequency range getting understated or overplayed. And while the Bowers & Wilkins can hit with more than enough purpose to make Holy Calamaf*** by Run the Jewels sound as assertive and uncompromising as anything, control of bass sounds is such that rhythmic expression is natural and coherent. The sort of dynamic variation that’s apparent in this recording is given free expression, too – there’s an appreciable amount of distance between the most and least intense passages.

The soundstage on which all of this occurs is large and properly defined. Despite the width and depth to the Px7 S3’s presentation, though, and despite the fact that every element of a recording enjoys a fair amount of space in which to operate, there’s a unity and singularity to the overall presentation that makes recordings sound of a whole. Even something like Aphex Twin’s Alberto Balsalm, which never was a performance, sounds somehow together.

Where active noise-cancellation is concerned, Bowers & Wilkins has made great strides with the Px7 S3. The headphones deal decisively with the majority of external sounds, and can do so without affecting their sonic signature in the slightest. That these headphones can’t do as complete a job on ambient noise as an equivalent pair of Bose will come as no surprise, because no other headphones can either, but now the Bowers & Wilkins ANC needs no excuses made for it. It’s a match of any of those ‘not quite Bose’ contenders from Sennheiser, Sony and so on.

In fact, about the only way I can imagine there is scope for worthwhile improvement is in suppression of wind noise. My part of the UK’s south coast is windy more often than it isn’t, and the Px7 S3 prove more susceptible to wind noise than quite a few alternative designs. It’s by no means a fatal flaw, but it’s noticeable nevertheless. And I guess it’s a measure of just how accomplished the Px7 S3 are that my contractually obliged complaining consists of some tepid bleating about how they could deal with wind noise a little better…

• Sound quality score: 5 / 5

Bowers & Wilkins Px7 S3 review: Design

• Choice of three finishes
• Slimmer profile, redesigned arms and headband
• Look and feel expensive (which is just as well)

On first acquaintance you’d be forgiven for thinking the Px7 S3 are the same as the outgoing Px7 S2e where design is concerned – certainly that’s what my first glance led me to believe. But Bowers & Wilkins has had a bit of a think about this new model’s design, and has made some very worthwhile adjustments without in any way affecting its perceived value.

For instance, the earcups are now appreciably slimmer in profile. Previous Px7 models have made the wearer look a bit, well, Cyberman-y – the earcups and pads were deep enough to increase the width of the wearer’s head more than somewhat. The Px7 S3 aren’t as slim as, say, the Sonos Ace, but they’re definitely tidier, and it makes for a less conspicuous look when they’re in position.

A new headband and redesigned arm mechanism makes the Px7 S3 ever so easy to get comfortable inside – an all-in weight of 300g has a part to play in this – while the pleather-over-memory foam contact points are nicely padded and reluctant to return your body heat too rapidly. And in a first for Bowers & Wilkins, the inner section of the headband and the earpads can be removed and replaced (by a trained service engineer, of course).

The fabric around the outside of the headband and the earcups looks and feels good, and will prove hard-wearing if previous Px7 models are anything to go by. The narrow grille that separates the outer part of the earcup from the earpads, first seen (on a much smaller scale) on the splendid Pi8 true wireless in-ears, allows mics and Bluetooth aerials to operate more freely, but the fact that it’s a nice design flourish doesn’t do any harm either.

The standard of build and finish is basically impeccable, and the concealed headband adjustment mechanism operates with well-damped precision. It doesn’t matter if you choose the ‘anthracite’ black of my review sample, ‘indigo’ blue or ‘canvas’ white, you’ll find yourself in possession of a pair of headphones with appreciable perceived value, which is just as well, given how much you’re paying.

The Px7 S3 can be kept in peak condition during transit thanks to a nice robust carry-case that’s just a few millimetres smaller in each direction than the case the Px7 S2e travelled in. As well as protecting the headphones, it features a pocket behind a magnetically closing flap that conceals USB-C / USB-C and USB-C / 3.5mm cables.

Bowers & Wilkins Px7 S3 review: Value

• Extensive specification
• Excellent standard of build and finish
• Class-leading sound

Just because it’s possible to spend plenty more than £399 on a pair of wireless noise-cancelling over-ear headphones (not least with Bowers & Wilkins itself), that doesn’t mean it’s an insignificant amount of money.

Happily, at every turn the Px7 S3 try their hardest to make it seem like a perfectly reasonable asking price. The standard of build and finish here is basically impeccable, and a thoughtful little redesign has resulted in a more discreet, yet somehow no less premium, appearance – pride of ownership is significant.

Specification is as good as it currently gets at anything like this sort of money. And where sound quality is concerned, you’re getting what I am confident is the most complete performance available at anything like this sort of money.

Should I buy the Bowers & Wilkins Px7 S3?

Buy them if…

Don’t buy them if…

Bowers & Wilkins Px7 S3 review: Also consider

How I tested Bowers & Wilkins Px7 S3

• Wireless connection to an Apple iPhone 14 Pro, wireless and wired connections to a FiiO M15S digital audio player
• A variety of music, a variety of file types and sizes
• Indoors and outdoors

Wireless listening used the AAC and aptX codecs (depending on the source player), while the wired listening was able to extend to 24bit/96kHz content.

I listened at my desk, I listened while on the street and I listened on public transport, to a wide variety of music of many different file types and sizes. I spent well over a week listening critically, and found myself listening simply for listening’s sake too.
