You have to restore factory settings and pair 2 temples again. Please follow the steps below.
1. Long press the temples on both sides to turn off the device, and “forget the device” on the mobile.
2. Put the glasses on again. When you hear the “power on” sound, take off the glasses, and double-click the LOGO placed on the temples twice at the same time. Then you’ll find the red lights and blue lights flashing, and there will be two “Jimhalo” devices shown on your mobile device (please do not connect now).
3. After waiting for about 15 seconds, the two “Jimhalo” devices will be paired and become one. You can connect to the “Jimhalo” device on the mobile now.
I am using the smart audio recently, will update the feedback soon!
