AB  - This paper presents results of a listening experiment evaluating three-degrees-of-freedom binaural reproduction of head-mounted microphone array signals. The methods are applied to an array of five microphones whose signals were simulated for static and dynamic array orientations. Methods under test involve scene-agnostic binaural reproduction methods as well as methods that have knowledge of (a subset of) source directions. In the results, the end-to-end magnitude-least-squares reproduction method outperforms other scene-agnostic approaches. Above all, linearly constrained beamformers using known source directions in combination with the end-to-end magnitude-least-squares method outcompete the scene-agnostic methods in perceived quality, especially for a rotating microphone array under anechoic conditions.
