This manual will tell you everything you need to know to get the most from your P17 headphones.Your PI7 can play music streamed wirelessly from your mobile phone, tablet, or computer via Bluetooth. PI7 can also be used for wireless telephony.PI7 Real-World Listening features include our latest innovations in Adaptive Noise Cancellation, Ambient Pass-Through, and enhanced Wear 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 conversation or safety announcements, to be heard clearly without any need to remove the headphones. The Wear Sensing feature enables PI7 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.PI7 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.

3.2 Voice AssistanceVoice Assistance is activated by pressing the right (R) earbud Multi-function button for 1 second. See Digram 2 for button location.3.3 Ambient Pass-Through PI7 features an 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 Bowers & Wilkins headphone App. The level of ambient pass-through, High/Low/Off, can be adjusted to suit your needs through the App.
3.4 Wear SensorsPI7 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, PI7 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.Wear sensors 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.
