Nothing here worked for me, but if you try everything else there is to try, then find the answer, now you are brilliant. So I did. Start from scratch and turn Bluetooth off on your device. Turn off both ear buds. Put them in the charging case. Take out the right one, put it in your ear, press to turn it on, then press twice. Pull out the left one, and just turn it on and now they are synced again. Turn them off. Turn on your Bluetooth device,, then turn on both earbuds. They will sync to the device. Worked the first time.
