Welcome to Bowers & Wilkins and PI5
Thank you for choosing Bowers & Wilkins. When John Bowers rst 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 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 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
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 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 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.
