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.
