2.5 Wear Sensors
PX7 also incorporates proximity sensors in both left and right ear pieces, allowing the headphones to sense
if it is worn on the head. This will enable the headphones to intelligently conserve battery by disconnecting
Bluetooth and enter stand by ten minutes after taking off, and wake when placed back on your head.
When playing media, the headphone will automatically pause the content when you take them off. If worn
again within ten minutes, content playback will resume.
Note: Take special care when wearing your headphones, hair or accessories trapped between your ears and
the ear pieces may interfere with proximity sensing.
