The invention relates to a listening device comprising an ear-part adapted for being worn in or at an ear of a user, a front and rear direction being defined relative to a person wearing the ear-part in an operational position. The invention further relates to a method of operating a hearing instrument, to its use, to a listening system, to a computer readable medium and to a data processing system. The object of the present invention is to provide localization cues for indicating a direction of origin of a sound source. The problem is solved in that the listening system comprises (a) a microphone system comprising at least two microphones each converting an input sound to an electrical microphone signal, (b) a DIR-unit comprising a directionality system for providing a weighted sum of the at least two electrical microphone signals thereby providing at least two directional microphone signals having maximum sensitivity in spatially different directions and a combined microphone signal, and (c) a frequency shaping-unit for modifying the combined microphone signal to indicate directional cues of input sounds originating from at least one of said spatially different directions and providing an improved directional output signal. This has the advantage of providing an alternative or an addition to natural localization cues. The invention may e.g. be used in listening devices, e.g. hearing instruments, head phones, headsets or active ear plugs.
