Intelligent Features
3.1 Adaptive Noise CancellationNoise 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 noisyenvironments such in an airplane cabin. |
| Low | Suitable for environments where youneed awareness of your surroundings. |
| Auto | Intelligently adapts noise cancellationbest suited to your current environment. |
| Off | Turns off the noise cancellation feature. |
3.2 Ambient Pass-Through
PX7 features an 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 ambientpass-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 customized to suit your needs using the Bowers & Wilkins Headphones App.
3.3 Wear SensorsPX7 incorporates 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 the 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 profile of your ears, may interfere with the performance of the proximity sensors.

The headphones can be used while charging.To charge:1. Please use the supplied charging cable and connect the USB-A plug to a wall charger or a powered computer USB-A socket.2. Then connect the USB-C end to the headphones USB-C socketNote: During charging, the headphone indicator will flash green. When fully charged, the indicator will remain illuminated. See Diagram 3 for status indicator details.
4.1 Standby Power SavingPX7 wear detection sensors intelligently conserve power. When taken off your head, PX7 will automatically enter standby which will pause media playback, disconnect Bluetooth and switch to a low power state.When worn again, PX7 will wake and reconnect to the last connected Bluetooth source. Note that both earpieces must detect wear for proper functionality. If wear sensors are disabled using the app, this feature will also be disabled.With the app, you can customise how long the headphones will wait before switching to auto standby, please see Standby Timer under Settings in the app.
