The present invention relates to a method for providing a user-specific sound signal for a first user of two users in a room, a pair of loudspeakers (1R, 1L; 2R, 2L) being provided for each of the two users, the method comprising the steps of: - tracking the head position of said first user, - generating a user-specific binaural sound signal for said first user from a user- specific multi-channel sound signal for said first user based on the tracked head position of said first user, - performing a cross talk cancelation for said first user based on the tracked head position of said first user for generating a cross talk cancelled user- specific sound signal, in which the user-specific binaural sound signal is processed in such a way that the cross talk cancelled user-specific sound signal, if it was output by one loudspeaker of the pair of loudspeakers of said first user for a first ear of said first user, is suppressed for the second ear of said first user and that the cross talk cancelled user specific sound signal, if it was output by the other loudspeaker of said pair of loudspeakers for a second ear of said first user, is suppressed for the first ear of said first user, and - performing a cross soundfield suppression in which the sound signals output for the second user by the pair of loudspeakers provided for the second user are suppressed for each ear of the first user based on the tracked head position of said first user.
