3. Intelligent Features
3.1 Environmental Controls
Active Noise Cancellation
Noise cancellation is a series of advanced
technologies that aids in removing undesired noise
from the surrounding environment. The Px7 S2
headphones use built-in microphones to pick up and
cancel out ambient sound for a more comfortable
listening experience.
Note: Noise cancellation requires a good seal
between the headphones and your head for
optimal performance.
Ambient Pass-Through
Px7 S2 also features an ambient "Pass-Through"
mode, which allows in some external sound from
the surrounding environment, allowing safety
announcements or conversations to be heard
without taking the headphones off.
By default, the Quick Action button on the left
earpiece will cycle through the following modes,
but the button can be customised from the
Bowers & Wilkins Music app. See Diagram 2 for
button location.
• Noise Cancelling On
• Pass-Through On
• Noise Cancelling and Pass-Through Off
3.2 Voice Assistance
Your connected device's voice assistant can be
assigned to the Quick Action button on the left
earpiece from the Bowers & Wilkins Music app.
See Diagram 2 for button locations and section
8.2 on using the Bowers & Wilkins Music app.
3.3 Wear Sensors
Power Saving
Px7 S2 incorporates our latest enhanced wear
detection sensors in both earpieces (see Diagram 3),
enabling intelligent battery conservation by pausing
media playback and entering low power standby
mode when removed from the head. When worn
again, Px7 S2 automatically wakes and connects to
the last connected Bluetooth device.
Playback Control
During media playback, Px7 S2 will automatically
pause when either earpiece is lifted from the ear.
If playback has been paused, placing the earpiece
back on the ear will resume playback.
The standby timer and wear sensor features can be
adjusted from the Bowers & Wilkins Music app.
Note: Take care when wearing your headphones;
hair or accessories trapped between your ears
and the earpieces, or wearing glasses that distort
the profile of your ears, may interfere with the
performance of the wear sensors.
4. Battery Charging and Power Saving
Your Px7 S2 comes with the battery partially charged
and may be used immediately. For best practice we
recommend you fully charge the headphones before
first use. Please allow up to 2 hours to fully charge.
The headphones can be used while charging.
To charge:
1. Use the supplied USB-C cable and connect
one end to a wall charger or powered
computer port.
2. Connect the other end of the cable to the
USB-C socket on the headphone's right
earpiece.
Note: During charging, the headphone indicator
will flash green. When fully charged, the indicator
will remain illuminated. See section 2.3 for status
indicator details.

5. Wearing Your Headphones
Wearing your headphones correctly will help ensure
the best possible experience. See Diagram 5.
1. Identify the left and right earpieces by finding
the identification legends located on the interior
of each earpiece.
2. Wear the headphones accordingly with
the headband adjusted so that they rest
comfortably on your head.
Note: Wearing glasses that distort the profile
of your ears may interfere with headphone
performance. Similarly, hair trapped between your
ears and the headphone earpieces may interfere
with the wear sensor performance.
