Welcome to Bowers & Wilkins and PI7
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.
PI7 is a high-performance in-ear headphone 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 PI7 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.

Getting to know your PI7

Switching Headphones On and Off

Switching On/Off
PI7 does not have a power control, instead, the power management is automatic. Your PI7 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 the paired device, streaming audio or placing the earbuds into your ears.

Intelligent Features

Adaptive Noise Cancellation

Noise cancellation is a series of advanced technologies that aid in removing undesired noise from the surrounding environment.
PI7 features our latest innovations in adaptive noise cancellation, this includes intelligent sensing that adapts noise cancellation and tuning best suited to your surrounding environment. As your surroundings change, noise cancellation will auto-adapt to complement your new environment.
The noise cancellation feature is activated by pressing the left (L) earbud Multi-function button for 1 second, additional 1-second presses cycle through the modes: On, Auto or Off. See Diagram 2 for button location.

Voice Assistance

Voice Assistance is activated by pressing the right (R) earbud Multi-function button for 1 second. See Digram 2 for button location.

Ambient Pass-Through

PI7 features ambient pass-through which lets some external noise from the surrounding environment, such as safety announcements or conversations, to
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.

Wear Sensors

PI7 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 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.

Custom Installation
CWM7.5 S2

See nothing, hear everything
The CWM7.5 shares the acoustic configuration of the 707 S2 and like its sibling, it houses a 130mm (5in) bass/mid-range Continuum cone driver plus a 25mm (1in) Carbon Dome tweeter, coupled to a forward-firing Flowport™ for an outstanding bass response from a relatively small footprint. It has a critically formed baffle constructed from glass-reinforced ABS plus its own integrated back box, ensuring retrofittable installation plus optimum performance. It’s an outstanding performer when used in stereo or multi-room installations, and is equally at home as the rear speaker in a larger theatre application.
