Bowers & Wilkins PX7 Manual page 12

Your headphones can connect up to two devices at the same time. However, you can only play audio or
take calls from one device at a time.
To switch between two devices:
1. Pause audio on the first device, or use the headphone's play/pause button.
2. Play audio from the second device and the headphone will switch over.
When streaming audio, receiving a call on the second device will automatically pause playback and the call
will be routed automatically to your headphones. Ending the call will automatically resume playback from
the first device.
