1. A hearing device for a binaural hearing system, the hearing device comprising:
a transceiver module configured to communicate with a contralateral hearing device of the binaural system, the transceiver module configured to receive contralateral data from the contralateral hearing device, the contralateral data comprising a contralateral directional input signal;
a set of microphones comprising a first BTE microphone for provision of a first BTE microphone input signal, a second BTE microphone for provision of a second BTE microphone input signal, and a first MIE microphone for provision of a first MIE microphone input signal;
a first beamformer connected to the first BTE microphone and the second BTE microphone for provision of a directional input signal based on the first BTE microphone input signal and the second BTE microphone input signal;
a second beamformer connected to the first beamformer and the transceiver module for provision of a binaural beamform signal based on a binaural transfer function, the directional input signal, and the contralateral directional input signal;
a spatializer connected to the second beamformer for provision of a spatial binaural beamform signal based on the binaural beamform signal and a spatialization transfer function;
a processor configured to provide an electrical output signal based on the spatial binaural beamform signal; and
a receiver configured to provide an audio output signal based on the electrical output signal.
