A mounting arrangement for a handset, neckset and the like having a transmit and a receive end. A regular-shaped cavity is provided at the transmit end for receiving a higher order microphone capsule, having two or more poles. The capsule is symmetrically fixed with the geometrical center substantially corresponding with the geometrical center of the cavity. The transversal size of the capsule is less or equal to the depth of the cavity. In this way, the capsule is embedded into the cavity, and the cavity is covered with an acoustically transparent screen. There is space left between the poles of the microphone and the facing walls of the cavity for fooling the microphone that it is in free space.
