Satisfied
Are uses at work I work in a school and have to do lunch duty and the decibel level is extremely loud to the point where my ears with her and I would have a headache. I hear what goes on when I have a conversation as well as the screaming in the background but it is muted. At to what level-I can’t answer that but I can say I am happy with these earplugs. And once I get to a concert I will update my review
