Bowers & Wilkins PI4
In-ear noise-cancelling wireless headphones
No headband, no compromise on quality.
Cancel noise and get immersed in your music with in-ear headphones built on the same rigorous standards that brought Bowers & Wilkins sound to Abbey Road Studios
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 transatlantic sounds a lot better with the PI4.
