The Bowers & Wilkins Pi5 S2 offers 100% wireless True Wireless in-ear headphones with active noise reduction (ANC), premium hi-fi sound quality, sleek aluminum design, and intuitive touch controls. With the smart pause feature, music automatically stops when you remove an earbud. The S2 version boasts improved battery life, enhanced wireless stability, and seamless music control through B&W’s dedicated Music App.

Equipped with support for aptX and AAC Bluetooth formats, the Pi5 S2 ensures optimal sound quality regardless of whether you use an Android or Apple device. Enjoy superior audio performance no matter where you listen, along with a tranquil listening experience thanks to ANC, all while maintaining the convenience of wireless freedom.


The Pi5 S2 can play for up to 5 hours on a single charge with ANC enabled. You can charge the earbuds a further four times in the included charging case, so you can have power for a whole day with music in your pocket. Charging can even be done wirelessly with a standard Qi charger, which you may already have for your phone. And should you realize on the way out the door that the Pi5 S2 is completely out of battery, thanks to the Fast Charge function you can get power for two hours of use in just 15 minutes.

The Bowers & Wilkins Pi5 S2 is available in several colors. Charging case, USB-C charging cable and 3 pairs of earplugs (S/M/L) included.


Smart and user-friendly touch operation, anc and dedicated bowers & wilkins music app

The Bowers & Wilkins Pi5 S2 features touch control on the earbuds for easy management of music and calls, eliminating the need to search for small buttons like some competitors. Additionally, the hear-through function can be activated to allow ambient sounds to come through, which is useful when navigating through traffic, for instance.

Voice control is the most convenient way to manage playback when the headphones are in your ears. By pressing the ear capsule, you can activate your preferred voice assistant on your phone (e.g. Google Assistant, Amazon Alexa, or Siri) and effortlessly control your music, respond to messages, or even locate the nearest pizza place.

For those who enjoy listening to music in environments where distractions are common, the smart pause feature is a game-changer. The Pi5 S2 automatically pauses your music when you remove one earbud, and resumes playback seamlessly once you’re done. This function can truly simplify a busy daily routine.


The built-in ANC microphones in each earbud pick up the noise from your surroundings and ensure optimal attenuation without at the same time putting a damper on the sound quality. With the accompanying Bowers & Wilkins Music app, you can customize both ANC, touch functions and calls to your personal taste. From the app, you can also stream music from a number of high-quality music services (TIDAL, Deezer, Qobuz and others). Then you have everything gathered in one place.
