The invention relates to a method for converting signals in two-channel stereo format to become suitable to be played back using headphones. The invention also relates to a signal processing device for carrying out said method. According to the invention left direct path (Ld) and left cross-talk path (LX) signals are formed from the left input signal (Lin), and correspondingly right direct path (Rd) and right cross-talk path (RX) signals are formed from the right input signal (Rin), and further the left output signal (Lout) is formed by combining said left direct-path (Ld) and said right cross-talk path (Rx) signals, and correspondingly, the right output signal (Rout) is formed by combining said right direct-path (Rd) and said left cross-talk path (Lx) signals. The direct path signals (Ld,Rd) each are formed using filtering (1,3) associated with first frequency dependent gain (Gd) and the cross-talk path signals (Lx,Rx) each are formed using filtering (2,4) associated with second frequency dependent gain (Gx) and by adding interaural time difference (ITD) (5,6).
