The headphones system uses an iteratively produced shift for each acoustic transducer which is directed downwards and forwards of the line of vision to provide forwards sound projection. Pref. the iterative shift is used to provide a simulated sound source directed downwards and forwards which is displaced in steps of at least 5mm, for empirical optimisation of the sound source position, the optimisation pref. effected separately for each ear. The optimisation may be effected for at least eight individuals representing a range of different hearing characteristics.
