Omni-directional perception in a binaural hearing aid system

A hearing aid system includes: a first hearing aid comprising a first set of microphones, a first beamformer, a first processing module, and a first receiver; and a second hearing aid comprising a second set of microphones, a second beamformer, a second processing module, and a second receiver; wherein the first beamformer in a first operating mode is configured to provide a first audio signal in accordance with a first primary spatial characteristic, wherein the second beamformer in the first operating mode is configured to provide a second audio signal in accordance with a second primary spatial characteristic, the first primary spatial characteristic having a first main lobe with a first direction, and the second primary spatial characteristic having a second main lobe with a second direction, wherein the second direction is different from the first direction.
