Large silicone ear plugs for water protection. Developed with an ear doctor, hearos pearls are the first “pre-rolled” silicone ear plugs. Through a patent pending process, hearos pearls take all the guess work out of using silicone ear plugs. Just remove the silicone “pearl” from the package and mold over the ear canal. No other silicone ear plug offers such quick, doctor recommended, ease of use. Ideal for all noise reduction, hearing protection and water protection needs.
