Our replacement foam ear plugs are designed to provide you with all day comfort while working on the job site. These interchangeable, comfortable earplugs are compatible with the Milwaukee® banded ear plugs. The noise-reducing earplugs are designed with a tapered shape to fit inside your ear canal, providing you with a noise reduction rating (NRR) of 25. The soft, comfortable foam expands quickly in your ear for a secure seal to protect against hazardous noise.
