Abstract
A waterproof earmold-to-earphone adapter is provided for use in conjunction with an earmold. The earmold has a passageway extending transversely therethrough to allow sound to pass through the earmold, and the adapter has a hollow, elongated stem which slides into and frictionally engages the passageway in the earmold. The adapter has a resilient, cylindrical holder carried by the stem, the holder being adapted to receive a waterproof earphone whereby sound from the earphone passes through the hollow stem directly into the user's auditory canal. The passageway of the hollow stem is of small enough diameter and great enough length to prevent water passing through, but allows air and sound to pass through.
