3. Intelligent Features
3.1 Adaptive Noise Cancellation
Noise cancellation is a series of advanced
technologies that aids in removing undesired noise
from the surrounding environment.
PX7 features our latest innovations in adaptive noise
cancellation, this includes intelligent sensing that
adapts noise cancellation and tuning best suited to
your surrounding environment. As your surroundings
change, noise cancellation will auto adapt to
complement your new environment.
The Noise Cancellation button on the left earpiece
is used to cycle between the following modes, see
Diagram 2 for button location:
Mode Application
High
Suitable for consistently noisy
environments such in an airplane cabin.
Low
Suitable for environments where you
need awareness of your surroundings.
Auto
Intelligently adapts noise cancellation
best suited to your current environment.
Off Turns off the noise cancellation feature.
3.2 Ambient Pass-Through
PX7 features ambient pass-through which lets some
external noise from the surrounding environment,
such as safety announcements or conversations, to
be heard without taking the headphones off.
The Noise Cancellation button on the left earpiece
also controls this feature, see Diagram 2 for button
location.
Function Action
Enable ambient
pass-through
Press and hold the Noise
Cancellation button for
2 seconds.
Disable ambient
pass-through
With ambient pass-through
enabled, either hold down
or single press the Noise
Cancellation button for 2
seconds, the headphones will
return to the previous noise
cancellation mode
The level of ambient pass-through can be further
customised to suite your needs using the
Bowers & Wilkins Headphones App.
3.3 Wear Sensors
PX7 incorporate our latest enhanced wear detection
sensors in both earpieces, see Diagram 4, enabling
intelligent battery conservation by entering standby
when removed from the head. When worn again,
PX7 automatically wakes and connects to the last
connected Bluetooth device.
During media playback, PX7 will auto pause when
either earpiece is lifted from the ear. Playback will
auto resume when the earpiece is placed back on
the ear. Auto resume has been further optimised
so it is ready only when you are. This means the
headphone will not attempt to resume playback
during following conditions:
1. Headphone powers on from the off state.
2. Headphone wakes from the standby state.
3. Headphone reboots (such as after a
factory reset).
Wear sensor and standby can be adjusted using the
Bowers & Wilkins Headphones App.
Note: Take care when wearing your headphones;
hair or accessories trapped between your ears
and the earpieces, or wearing glasses that distort
the prole of your ears, may interfere with the
performance of the proximity sensors.
