Please try the following steps :
- Normally, when the primary earbud is turned off you'll need to wait 3-4 seconds for the secondary earbud to automatically connect to your device.
- If it doesn't connect, you can manually connect by clicking on the secondary earbud's Bluetooth name in your phone's Bluetooth list.
- If this doesn't work, reset the earphones. See "How do I reset Life Note?".
