The headset further comprises a digital active noise reduction unit (ANR) for performing active noise reduction based on the sound recorded by the at least one outer microphone and the at least one inner microphone. The active noise reduction unit (ANR) comprises an analysis unit (AU) for analyzing the sound recorded by the outer microphone and the inner microphone and for determining the signal types of the recorded sound. The active noise reduction unit further comprises a plurality of signal processing units (SVE1 - SVEn), which are each designed to perform active noise reduction for a signal
