    Abstract: The application relates to a binaural hearing assistance system comprising left and right hearing assistance devices, and a user interface, to its use and to a method. The left and right hearing assistance devices comprises a) at least two input units for providing a time-frequency representation of an input signal in a number of frequency bands and a number of time instances; and b) a multi-input unit noise reduction system comprising a multi-channel beamformer filtering unit operationally coupled to said at least two input units and configured to provide a beamformed signal. The binaural hearing assistance system is configured to allow a user to indicate a direction to or location of a target signal source relative to the user via said user interface. This has the advantage that interaural cues of the target signals can be maintained, while the ambient noise is reduced.
