Bowers&Wilkins PI4
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.
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, the drivers ensure you stay immersed in music wherever you go.
Move freely with noise-cancelling microphones that cut out distractions before they reach your ears—keep out the buzz of traffic, terminals, subways, and cubicles. The new aptX codec gives you pure, unmatched audio, whether you're traveling, moving, or standing still in the sound.
10-hour battery life allows you to go from AM to PM without missing a beat. If that's not enough a 15-minute quick charge gets 3 hours of immediate playback. A transcontinental flight sounds a lot better with the PI4.
Magnets clip the earpieces together when you take them off, automatically pausing the music. Unclip them and pick up where you left off.
Silicone and rubber together make the PI4 feel specifically designed for how and where you listen. These soft but durable materials are designed for how you live, one moment at a time.
