The fitting of hearing aids and other hearing devices is intended to be made more comfortable. For this, provision is made for a hearing device with a housing which contains a signal processing unit and has a sound outlet. A supporting hook for attaching the hearing device to an ear or a head can be fixed on the sound outlet of the housing such that sound emanating from the sound outlet is guided through the supporting hook. A sensor for detecting the type of supporting hook is arranged in or on the housing. The sensor controls the signal processing unit as a function of the detected type of supporting hook. Thus, the user can for example use different types of supporting hooks without having to decide on a type of supporting hook during the first fitting. Moreover, the degree of mass production of the hearing aid can be further increased by the automatic recognition of the type of supporting hook.
