A hearing device is proposed comprising at least one microphone (1), at least one analog-to-digital converter (2), a signal processing unit (3), a communication unit (6) for establishing and/or maintaining a communication link to a second hearing device, and a detection unit (7) for determining a communication link quality. The at least one microphone (1) is operationally connected to the signal processing unit (3) via the at least one analog-to-digital converter (2), and the communication unit (6) is operationally connected to the signal processing unit (3). By providing said detection unit (7), which is operationally connected to the communication unit (6), together with a processing scheme selectable in the signal processing unit (3) in accordance to a determined communication link quality, a binaural hearing system with two hearing devices is for able to adjust its mode in line with the communication link quality, and therewith its capacity.
