I work in a noisy office with a really irritating air conditioning duct above me. I bought these to try and blot out the noise so I could concentrate. It was cutting through my noise isolating headphones that I use for monitoring recordings. These cancel this out.

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

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!

Bought these to replace a ageing pair of sony mdr1 nc and wow! Sublime sound, top build run them in use a good source and sing these babys do! Better than any at price simply stunning pair of headphones, i got the gold and blue love them best i have ever owned.

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.

The buttons on the headphones are of very high quality and they just simply work each and every time. The sound is balanced between the mids, highs and lows. The build quality is second to none and the warranty is two years out of the box.

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

Every purchase of consumer tech is defined by the choices we make about what we value more. In the world of over-ear headphones, the question has up until now been a three-way tug-of-war between the contradictory desires for wireless and noise-canceling tech, lightweight and compact design, and the...

Best sound from noise-canceling headphones; Plentiful battery life; USB-C charging and connection versatility; Durable and attractive design; Headphones pause automatically when you take them off

Sound can be a bit too edgy and forward for listening at home; More comfortable when worn on the move than sat in front of a desk; Automatic pause can be finicky; Bluetooth pairing is as nightmarish as most other wireless cans
