E-A-R Classic Superfit-33 PVC Foam Ear Plugs Corded (NRR 33)

E-A-R Classic SuperFit-33 PVC foam ear plugs give you the benefits of easy insertion like the Classic, but with the higher rating formerly only available in UF foam ear plugs. The visual indicator stripe on each ear plug tells you definitively if the user has the earplugs properly inserted. If the center stripe is still visible once the ear plug has been inserted into the ear canal and allowed to expand, the ear plugs are not fit properly and must be reinserted more deeply to provide their full NRR 33 protection from sound. Getting a good fit with hearing protection is absolutely critical, and SuperFit 33 makes it simple and easy. See Also
