@userN2YWHX23Kc Did you try thhe troubleshooting link provided?
I recently got the Galaxy buds and after 2 weeks of light use, the right earbud went very quiet. The left works as normal but the right one suddenly went quiet. Both are fully charged as is the case.
Any help would be greatly appreciated.
Try resetting the buds via Galaxy Wearable app. If didn't help, contact Samsung Tech support:
