If you’re looking for class-leading wireless, noise-canceling headphones and you’re not put off by a premium price tag, Bowers & Wilkins’ latest flagship pair is well worth considering. The cheaper Sony WH-1000XM3 rivals may be slightly better valued, but with best-in-class sound quality and design, not to mention very decent ANC and battery life, the PX7s are stellar acts indeed. Let’s find out “Bowers & Wilkins PX7 Wireless Headphones review” in this article!

The PX7 is an over-ear, closed-back headphone. The housings are large enough to completely encase the ear and provide a natural degree of isolation even before the software is turned on. At the same time, they also leak very little noise to the outside world. Internally, each housing mounts a single dynamic driver that is an exactingly specific 43.6mm across. This, as Bowers & Wilkins themselves point out, is a fairly large driver for a headphone of this nature. This translates into a quoted frequency response of 10Hz-30kHz which is far from the most enormous figure quoted but more than sufficient to cover off the spectrum of a Mk 1 human ear.


Decent design, effective noise cancelation, competitive features: check, check, check. Now all they need to do is sound good – which, as those who’ve spied our star rating will no doubt have guessed, they do.

The PX were sonic high fliers when they came along two years ago, but since then rival headphones brands caught up – ‘tis the way in the ever-evolving tech world, after all. The good news for Bowers & Wilkins, and of course consumers, is that the PX7s push that performance parameter along with a sound that is as accomplished and thus enjoyable as they come in a pair of wireless noise-cancelers.

Competitive active noise-cancelation

Bowers & Wilkins’ active noise-cancellation was one of my disappointments when I tested the PX5 headphones, but things are better with the PX7s. I wore them on two flights and a long-distance train journey and was satisfied with the ANC. I’d still recommend sticking to the highest setting though, as I did with the more portable on-ear PX5s, if it’s total silence and listening isolation you are looking for.

Built from legend

The 43.6mm drivers in the PX7 are the largest in our headphone collection and are developed and tuned by the same engineers behind the Bowers & Wilkins 800 Series Diamond loudspeakers found in Abbey Road Studios.

Sublime sound

If you’re going to spend this kind of coin on a set of wireless headphones, the sound quality had better be awesome. The PX7 do not disappoint. It’s easy to say words like “full,” “rich,” or “detailed,” when describing what a given set of headphones sound like. But when it comes to the PX7, it’s not just lip-service. They deliver all of these attributes in a big way. The sound is both expansive yet intimate — a difficult juxtaposition to pull off — with the highly desirable ability to reveal layers to your favorite tracks that lesser headphones or earbuds simply can’t do.

Bass is deep and satisfying without becoming overbearing. The treble soars clearly and freely, as it should, while the midrange is almost always able to hold its own against these two competing forces across a wide variety of genres.

The PX7 do a respectable job with garden-variety MP3s, but as with any pricey cans they only truly show you what they can do when you give them something more weighty like Tidal’s HiFi collection of CD-quality and hi-res tracks.

It’s worth noting that the PX7 have incredible support for Bluetooth codecs: SBC, AAC, aptX, aptX HD, and even the latest aptX Adaptive are all on tap.

Great battery life

The B&W PX already had very good battery life at 22 hours, but the PX7 raises this number to 30, according to B&W. That’s the same battery life as the Sony WH-1000XM3 mentioned above, and I don’t think the claim is overstated: After running the PX7 for 17 hours straight, at 50% volume and with ANC on, the battery indicator within the app showed about half its life remaining. If you need a quick top-up, 15 minutes of charging will get you an additional five hours.
