Auto on/off feature
What is it?
Auto on/off is a feature that automatically shuts off the device when it is not connected to a 3.5 mm cable. It will help you to preserve your battery.
How it works
- Unplug the cable from the headphones to activate the auto on/off function and to switch off the device.
- To utilise noise cancellation without listening to audio, plug the cable into the headphones but do not connect to an audio source.
