PI7 Wireless Headphones

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.

 Wearing Your Headphones

Wearing your headphones correctly will help ensure you get the best possible experience, see Diagram 5. Like many in-ear earphones, PI7 earbuds are designed to seal the ear canal in order 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 PI7, and the advanced features such as Adaptive Noise Cancellation, perform optimally.

1. Identify the left and right earbuds by finding the L and Re-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.
