Welcome to Bowers & Wilkins and PI4
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. His belief is one that we continue to share
and inspires every product we design, tailored for new audio experiences
outside of the home.
The Bowers & Wilkins PI4 are high performance in-ear headphones 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 PI4
headphones.
Your PI4 headphones can play music streamed wirelessly from your mobile
phone, tablet or computer via Bluetooth and used for wireless telephony.
PI4 can also play audio while being charged via USB.
PI4 Real World Listening features include our latest innovations in Adaptive
Noise Cancellation, Ambient Pass-Through and Magnetic Clip Sensor
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 Magnetic Clip Sensing feature enables the
PI4 to respond naturally, pausing and resuming the music simply by clipping
the earpieces together. These features can be enabled and further customised
via the Bowers & Wilkins Headphone App available for fr ee on iOS and
Android devices.
PI4 headphones incorporate a rechargeable battery pack. When fully charged
and depending on the degree of Bluetooth, Adaptive Noise Cancellation and
Ambient Pass-Through use, the battery pack can provide up to 10 hours of
continuous wireless media streaming with noise cancellation enabled at average
playback volume levels.
