The Milwaukee® ear plugs are designed to provide all day comfort while on the jobsite. The soft comfortable foam expands quickly in the ear for a secure seal to protect against hazardous Nise. The Nise reducing ear plugs have a tapered shape to comfortably fit inside the ear canal, providing a Nise reduction rating (NRR) of 32 dB. Individually sealed pairs of foam earplugs are available in bulk for easy distribution on the jobsite.
