This is one impressive pair of portable headphones. I'm using these for my daily commute to London and can't fault them. Sound is incredible, build and finish is first class. Don't hesitate, just buy!

Let's hope this is an early hiccup for the new team leading B&W. Since we tested two pairs, we're confident that we at least had an experience that will be similar to what customers will encounter, though it's possible we were sent two defective units.

Powerful audio performance with rich bass and crisp highs; Comfortable, stylish design; Cable included for wired use; Noise cancellation can be turned off; App allows for nuanced NC adjustments

Expensive; Glitchy in testing; NC changes audio performance noticeably; Can't be used in wired passive mode-cable requires power

The Bowers and Wilkins PX headphones provide noise cancellation that doesn't alter how music sounds, and a comfort level that means you won't want to take them off.

Full; rich sound quality; Three noise-cancellation modes; Noise cancellation doesn't drastically affect sound; Wonderfully comfortable; AptX HD

You'll need an AptX HD device to get the best from them; No USB Type C audio in

Bowers & Wilkins is best known for its hi-fi speakers, but the company also puts out some fantastic headphones. The B&W PX is its first crack at a set of wireless, noise-cancelling headphones.

Fantastic sound; Handy smart sensors; Auto power/connect/play; Attractive design

Noise cancellation could be stronger

Bowers & Wilkins first attempt at active noise-cancelling wireless headphones are accomplished and clever, they come with tonnes of tech but it is the superb audio performance that really shines.

Four levels of active noise-cancellation; Beautiful design notes; Super soundstage with control over clarity and bass in equal measure; Wear sensor that switches them off when not in use

Foldable design could have been adopted; Pricier than some already direct rivals

Bowers & Wilkins has finally joined the noise-canceling Bluetooth headphone arena. At $399, the company's PX headphones are more expensive than the recently updated Bose QuietComfort 35 II, our Editors' Choice. Unfortunately, B&W tries to do more than necessary here, which results in a rare misfire from the typically reliable company. The PX's noise cancellation itself is decent, but using it impacts the audio profoundly, the auto-play/pause feature is beyond glitchy, and the headphones are simply overpriced. To say we're surprised is an understatement. Design Available in either a gray-and-black or a stunning navy-and-gold finish, the PX headphones look a bit different than previous B&W offerings, with earcups that are more rounded than the company's other circumaural (over-the-ear) models.

The Bowers & Wilkins PX wireless headphones are a rare misfire from the iconic audio company, with buggy operation and audio performance that changes when the noise cancellation is enabled.

Expensive; Glitchy in testing; NC changes audio performance noticeably; Can't be used in wired passive mode—cable requires power

Wireless noise-cancelling headphones feel like the pinnacle of headphone technology. It's here that you'll find all the major brands really flexing their audio muscles.

Noise-cancellation impresses; Auto pause-play works well; USB-C charging

Sound lacks definition; No classic B&W black leather

For most of us, peace and quiet is a rarified commodity. Cities throng with static noise, offices are abuzz with chatter, and even empty homes are filled with the hum of fridges, extractor fans and washing machines.

Gorgeous looks; Adjustable noise-cancellation works well; Balanced; natural sound

Headband is uncomfortable for long periods; Treble is a tad soft

Bowers & Wilkins has established itself as a top player in the headphone market over the last few years, but the firm hasn't branched into noise cancelling… until now. Here's our Bowers & Wilkins PX review.

The Bowers & Wilkins PX is a classy product with high-fidelity audio, although it's not the best value at $400.

High fidelity audio Stylish looks Quality build Straight-forward to use

Auto turn-off not implemented well Audio prompt for noise cancelling is needed
