Abstract: The two-way communication earpiece is a small, inconspicious, and comfortable earpiece which fits behind the ear for sound delivery and pickup. The earpiece may be used with a variety of communication devices, such as telephones, cellular telephones, two-way radios, radios, tape players, CD players, and televisions. The earpiece is configured to be received behind the ear of a user with a sound delivery tube extending from behind the ear into the ear canal of the user. An eartip positioned on the sound delivery tube is preferably a non-occluding type eartip which allows ambient sound to enter the ear canal around the eartip. A microphone is positioned on the earpiece above the ear for voice pickup.

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.
