Thankyou. Glad to help and EID Mubarak.

Ok so you have to remove metal part from buds with a small tools and have to clean it

Low volume on both buds or only right one ?

Ok first of all see if your buds have the latest update on samsing wearable app sec go to bluetooth and unpair them and connect again and go to samsung wearable all and go in earbus setting and reset buds
