Abstract

The invention relates to a device (10) for playing back audio signals, particularly over a set of earphones (12), with which the sound impression can be modified by digital filter means whose filter effect is dependent on filter data stored in the device (10). According to the invention, the device (10) has a data interface (14) via which filter data and/or filter base data can be fed to the device (10) and out of which filter data can be determined. The invention also relates to a method for modifying filter data, which influence the filter effect of digital filter means that, in turn, modify the sound impression of a device (10) for playing back audio signals.
