Abstract

A cerumen protection plug for a hearing device. The cerumen protection plug prevents cerumen from passing along a sound conduit in the hearing device and blocking sound output from a receiver in the hearing device. The cerumen protection plug includes a circular plug containing a cerumen barrier. A positioning handle allows the cerumen barrier to be positioned along the sound conduit, where it prevents cerumen that has entered the sound conduit from traveling along the sound conduit to the receiver or an output port of the receiver.
