B&W PI-4 In-Ear Wireless (Black)
In-ear noise-cancelling wireless headphones
No headband, no compromise on quality. Get immersed in your music with noise-cancelling in-ear headphones built to the same rigorous standards that brought Bowers & Wilkins sound to Abbey Road Studios.
Designed for Movement
Customized 14mm drivers pack full sound in a small space. Designed by the same team behind our 800 Diamond Series speakers used in Abbey Road Studios, the drivers ensure you stay immersed in music wherever you go.
Don’t miss a thing
No matter what you're listening to, watching or playing, hear what you were meant to hear. The new aptX codec gives you pure, unmatched audio, whether you're traveling, moving, or standing still in the sound.
Adaptive Noise Cancelling
Move freely with noise-cancelling microphones that cut out distractions before they reach your ears—keep out the buzz of traffic, terminals, underground, and office environments.
AM to PM on one charge
12-hour battery life allows you to go from night to day without missing a beat. If that’s not enough, a 15-minute quick charge gets three hours of immediate playback. Flying transcontinental sounds a lot better with the PI4.
Fits like no other
Soft silicone and rubber together make the PI4 feel specifically designed for how and where you listen. Soft and durable, these headphones are built for how you live, every moment and every day.
Drop to pause
Magnets clip the earpieces together when you take them off, automatically pausing the music. Unclip them and pick up where you left off.
