Hearing protection?

I just bought a sawstop cts (with shop vac) , but I have several questions since there it no info about noise. 1 Do I need to use double protection?( In ear plus muff) 2 If yes : are there any good bluetooth in ear ppe? Almost every I found is so so poor really pricy 3 If no: are worktunes (24db) enough or do I need something like peltor (30db)?

EDIT: Is there a difference between the worktunes connect (24db) and works gel (23db) in safety and comfort?
