An ear plug provides, in the exemplary embodiment, an ear plug body adapted to fit against a cavum conchae of the ear and defining an outwardly opening main cavity therewithin. An inner end of the ear plug body is sized and configured for fitting into an ear canal of the ear, while a base of the main cavity defines a sound hole that extends down through each of the base and inner end. A chamber wall is positioned within and extends across the main cavity, forming a hollow air chamber in fluid communication with the sound hole capable of selectively clearing any water droplets that may enter the main cavity and obstruct the sound hole. In an alternate embodiment, the base of the main cavity provides an upwardly protruding sound hole body configured for elevating an opening of the sound hole a distance above the base.
