Noise cancelling wireless headphones
PX combines best-in-class sound with adaptive noise cancellation, 22-hour battery life and intelligent controls that respond naturally to your behavior, for a totally intuitive listening experience.

Lose the distractions. Feel the music.

"It’s a winning combination: the B&W PX are the finest wireless, noise-cancelling headphones on the market."
Trusted Reviews

"With generous battery life, deeply immersive and emotive sound, and a compact enough shape to be carried everywhere, I now consider them essential."
The Verge

Controlled by instinct
Controlling PX feels completely intuitive, thanks to built in sensors that respond to the way you naturally use a set of headphones.

Put it on and it turns on. Take it off and it returns to stand-by mode. Lift an ear cup to talk, or hang it round your neck, and PX pauses the music, resuming playback when you’re ready to listen. It’s as if PX is an extension of you, always perfectly anticipating your needs.

Fine tune your environment
With the PX app, it’s easy to switch between noise cancellation modes.

Tweak settings such as environment filters and voice pass-through.

Keep up to date with the latest firmware.
