@rnm14780_10: Have you tried the accepted solution in this thread to see if that works for you? If one of your Buds isn't working, please take a look at the steps below to see if they help at all.
1. Place your faulty Bud in the charging case, make sure that the charging contacts on the Bud and case are in contact with each other and are clean of any foreign materials. Does the charging light turn red? If not, try charging the case for 10-15 minutes, then try again.
2. Try cleaning the affected Bud:
- Remove the ear tip from the earbud carefully. Don't use force to remove the ear tip.
- Clean the sensor, mesh and ear tip with a clean, soft cloth.
- Clean the receiver with a cotton swab and dry brush to remove any foreign materials.
- Reattach the ear tip onto the earbud when you've finish cleaning.
Please note: do not use liquids, such as alcohol or soapy water, when cleaning the Galaxy Buds.
3. Put your Galaxy Buds back in their case for 10-15 seconds. Reopen the case to enable Bluetooth, and check your mobile device's screen. If the Galaxy Buds don't connect to a mobile device within 3 minutes, Bluetooth connecting mode will automatically turn off.
