Abstract: The disclosure relates to a microphone arrangement comprising at least three groups of microphones that are mounted on a head-wearable support structure. The at least three groups of microphones comprising a first group of microphones with one or more microphones, a second group of microphones with one or more microphones, and a third group of microphones with one or more microphones, wherein the first group is mounted to a casing that accommodates signal transmission circuitry, the second group is mounted to slide with respect to the casing and the first group is mounted in a direction of a first axis. Furthermore, the third group comprises either at least one microphone that is arranged on the support structure so as to exhibit less sensitivity for sound coming from a user's mouth than for sound coming from a user's environment when the microphone arrangement is head-worn; or at least two microphones that are arranged symmetrically with respect to a user's head when the microphone arrangement is head-worn and that provide for a directionality that is orientated to the direction of a user's vision; or both.
