A Hearing apparatuses is provided. The hearing apparatus includes a programming socket that features at least a first connection and a second connection, with a signal processing system that is connected to the second connection, and with a control system. The control system taps the potential of the first connection. The control system furthermore engages the signal processing system in a first function when the first connection reaches the predetermined potential and in a second function when the potential of the first connection deviates from the predetermined potential. This enables multiple usages for example of the input of a programming interface of a signal processing IC.
