Welcome to Bowers & Wilkins and PI5

Thank you for choosing Bowers & Wilkins. When John Bowers first established our company, he did so in the belief that imaginative design, innovative engineering, and advanced technology were keys that could unlock the enjoyment of audio in the home.

PI5 is a high-performance in-ear headphones designed to deliver the highest quality mobile personal audio experience combined with the convenience of wireless operation and the serenity of noise-cancellation. This manual will tell you everything you need to know to get the most from your PI5 headphones. Your PI5 can play music streamed wirelessly from your mobile phone, tablet, or computer via Bluetooth. PI5 can also be used for wireless telephony.

PI5 Real World Listening features include our latest innovations in Adaptive Noise Cancellation, Ambient Pass-Through, and enhanced Sensing technologies. Our latest generation noise cancellation feature was designed from the ground up with intelligent environment sensing capabilities, automatically selecting the appropriate type of noise cancellation best suited to your surrounding environment, its only goal is to deliver an uncompromised listening experience. Ambient Pass-Through enables external sounds, such as conversations or safety announcements, to be heard clearly without any need to remove the headphones. The Wear Sensing feature enables PI5 to respond naturally, pausing and resuming the music simply by lifting either earpiece on or off your ear. These features can be enabled and further customized via the Bowers & Wilkins Headphone App available for free on iOS and Android devices.

PI5 incorporates a rechargeable battery case. When fully charged, depending on the degree of Bluetooth, Adaptive Noise Cancellation, and Ambient Pass- Through use, the battery case can provide up to 20 hours of continuous wireless media streaming with noise cancellation enabled at average playback volume levels.

Getting to know your PI5

Switching Headphones On and Off

Switching On/Off

PI5 does not have a power control, instead, the power management is automatic. Your PI5 earbuds will automatically charge when placed into the charging case and will be ready to use when they are removed from the case. When your earbuds are removed from the charging case, and not used for 5 minutes, they will enter a power saving mode. To exit power saving mode, start using the earbuds again by connecting your paired device, streaming audio, or placing the earbuds into your ears.

Headphone Controls

Each earbud has a Multi-function button located on the top cap of the earbud, see Diagram 1. The Multifunction button controls are as follows:

Ambient Pass-Through

PI5 features ambient pass-through which lets some external noise from the surrounding environment, such as safety announcements or conversations, be heard without taking the headphones off. Ambient pass-through can be enabled or disabled through the Bowers & Wilkins headphone App. The level of ambient pass-through, High/Low/Off, can be adjusted to suite your needs through the App.

Wear Sensors

PI5 incorporates our latest enhanced wear-detection sensors in both earbuds. The sensors enable intelligent battery conservation by entering power-saving mode when removed from the ears. When worn again, PI5 automatically wakes and connects to the last connected Bluetooth device.

The sensors will also pause audio when the earbuds are removed from your ears. Playback will auto-resume when the earbud is placed back in the ear. The auto-resume has been further optimized so it is ready only when you are. The wear sensor can be turned off from the Bowers & Wilkins Headphone App.

Note: Take special care when wearing your earphones, hair, or accessories trapped between your ears, and the earbuds may interfere with proximity sensing.

Wearing Your Headphones

Wearing your headphones correctly will help ensure you get the best possible experience, see Diagram 5. Like many in-ear earphones, PI5 earbuds are designed to seal the ear canal to perform optimally. Ear tips come in three sizes (small, medium, and large). Finding the proper size for your ear is critical to obtaining a good seal and ensuring PI5, and the advanced features such as Adaptive Noise Cancellation, perform optimally.

1. Identify the left and right earbuds by finding the L and R identification located on the inner side of each earbud.
2. Place the earbuds in your ear and twist the earbud backward slightly so that the tips engage comfortably with the opening of the ear canal.
3. If the earbud tip feels too large or small try another size ear tip to ensure the best possible fit.

Note: To optimize call quality, please ensure the microphone located underneath the earbud is facing outward, see Diagram 5.
