Milwaukee Ear Plugs are designed to provide you with all-day comfort while working on the jobsite. The soft comfortable foam expands quickly in your ear for a secure seal to protect against hazardous noise. The noise-reducing ear plugs are designed with a tapered shape to comfortably fit inside your ear canal, providing you with a Noise Reduction Rating (NRR) of 32db. Individually sealed pairs of foam earplugs are also available in bulk, allowing you to easily distribute them on the jobsite. (See boxed option)
