A behind-the-ear hearing aid component employs a multi-functional module easily replaced to enhance repairability and time to market. The multi-functional module is removably secured to a case that carries a microphone, a programming system that receives and stores one or more hearing aid programs, an optional selector for selecting one of a plurality of hearing aid programs, a signal conditioning circuit for conditioning the microphone signal according to a hearing aid program to produce a conditioned microphone signal, and a battery for powering the hearing aid component. A receiver converts the conditioned microphone signal to conditioned sound that is output to an external sound conductor, such as an earhook or tube and tip, which conducts the conditioned sound to an ear of the user.
