Abstract
An earpiece for a sound delivery system has a sound output port for delivering sound into the ear canal of the user. A cerumen block is provided to prevent cerumen or earwax from blocking the sound output port of the earpiece. The cerumen block is formed by a small flap of material which covers the sound output port and blocks cerumen from entering the sound output port in a closed position while allowing sound to pass around the flap and enter the ear canal in an open position. A resilient hinge returns the cerumen flap to the open position once the earpiece has been placed within the ear canal.
