Abstract
A method for reducing crosstalk in a headset connected to an audio device, in which the includes a left headphone, a right headphone and a common ground for the left headphone and the right headphone includes determining a frequency dependent impedance of the headset. The method also includes determining a frequency dependent impedance of the common ground, and determining a frequency dependent substantially optimum cross feed for attenuating crosstalk in at least one of the left headphone and the right headphone based on the impedance of the headset and the frequency dependent impedance of the common ground. The method further includes applying the frequency dependent substantially optimum cross feed to attenuate the crosstalk in the at least one of the left headphone and the right headphone.
