You can , drill the hole in your ball sinker slightly larger , and super glue a piece of earbud , put the glue on the outside of the bud .
But keep in mind , you are going to fish bottoms , you will hardly have you sinker running up and down , you are Basicly fishing up , and unless your lead are on the floor , and the fish are speeding away with a open drag .
I would not be too concerned .
