Welcome to Bowers & Wilkins and PI5

engineering and advanced technology were keys that could unlock the
enjoyment of audio in the home.

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 Wear Sensing technologies.
Our latest generation noise cancellation feature was designed from the ground

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 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 customised via the Bowers &
Wilkins Headphone App available for free on iOS and Android devices.
PI5 incorporates a rechargeable battery pack. When fully charged, depending on

wireless media streaming with noise cancellation enabled at average playback
volume levels.

7. Wearing Your Headphones
Wearing your headphones correctly will help ensure you get the
best possible experience, see Diagram 5.
Like many in-ear earphones, the PI5 earpieces 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 ensure PI5 and the advanced features such as Adaptive
Noise Cancellation performs optimally.
1. Identify the left and right earbud by finding the identification
legends located on the inner side on each earbud.
2. Place the earbuds in your ear so that the tips sit comfortably
at the opening of the ear canal.
3. Ensure the earbuds are sitting comfortably in the ear. Try
another size if they do not fit. Different sized ear tips can be
used 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
