Protective facilities in microphone inputs of a hearing device should be able to be exchanged in a more user-friendly manner. For this purpose, provision is made for a cover fixture for at least one microphone input of a hearing device with an essentially acoustically permeable protective facility to protect the at least one microphone input against solid particles. The cover fixture can be fixed to the surface of the hearing device in a friction-fitted or form-fitted manner. The cover fixture can however also be designed in one piece with the upper shell of the hearing device.
