Binaural hearing device with monaural ambient mode

A hearing device comprising

• a first earphone comprising a first driver unit, a first ambient microphone configured for converting ambient noise to a first ambient input signal,
• a second earphone comprising a second driver unit,
• a first electric circuitry configured to receive the first ambient input signal from the first ambient microphone and in an ambient mode outputting a first ambient output sound signal of a certain level to the first driver unit,
• an activation circuit configured to activate and deactivate the ambient mode for the hearing device,
• wherein in the ambient mode, the first ambient output sound signal is sent to the first driver unit and not the second driver unit;
• and
• wherein the activation circuit comprises a motion detector configured to detect a motion of the hearing device and generate a motion output signal in dependence on the detected motion, and in that the ambient mode is activated and deactivated in dependence of the detected motion.
