Title: Earplug shaper having curved shaping surfaces

Abstract: An earplug shaping device compresses a compressible earplug prior to insertion of the earplug into a user's ear canal. The device includes a first member and a second member which rotate with respect to each other. The outer surface of the first member and inner surface of the second member define a space that decreases in size as the first and second members rotate with respect to each other, thereby compressing the compressible earplug. Various embodiments of the earplug shaper employ a ratchet mechanism permitting substantially only one direction of rotation.
