My right ear bud volume is lower than the left

Alex. Did you recently drop the ear bud? You can do a find my buds in your phone setting. Set both buds about 2-3 feet apart and listen to the volume from both. If the one is still lower than the other, and you've adjusted the volume manually through your Samsung Galaxy wearable app, more than likely the one bud is damaged. And of course, make sure it's fully charged and free of ear wax. Lol.
