The invention is aimed at enabling a hearing system, particularly a binaural hearing aid system, to be controlled in an easy manner, taking into account the small amount of installation space available. A hearing system is provided comprising a first hearing device and a second hearing device. The first hearing device has a permanent magnet. The second hearing device has a magnetic field sensor such that the second hearing device is controlled in a predetermined manner when the first hearing device is located in close physical proximity to the second hearing device and consequently the magnetic field sensor detects the magnetic field of the permanent magnet or a corresponding magnetic flux. The sensor signal is used in particular for switching off the second hearing device. The first hearing device preferably possesses a mirrored structure so that it is controlled or switched when it is brought closer to the second hearing device.
