Insert the earbuds into the charging case, and then close the lid. Wait 7 seconds or more, and then remove the earbuds from the case.
Should this not work kindly take the buds to an accredited service centre for an inspection. Use the link below to find a service centre near you
Performing a restart on the earbuds, resetting the Bluetooth connection, or updating the Galaxy Wearable app will normally fix the issue.
