Hi all, I'm looking to get some good earplugs, ie. non-disposable, effective enough to replace ear defenders (except for really loud bangs). Can I have some good recommendations please
You can get to an NRR of 36, but that requires the highest rated muff (NRR 30 or 31) and the highest rated plug (NRR 33) to be worn at the same time.
