A great pair of passive ear muffs are a very effective way to protect your hearing. Ear plugs can be effective only if they are properly inserted into the ear. Very often, due to discomfort or improper training, the ear plug does not provide the level of protection advertised. A comfortable, well designed pair of ear muffs can help protect your hearing for years. Proper fitting is essential to adequate protection. Pro Ears provides different sizes of passive ear muffs for superior passive hearing protection.
