An active noise reduction headset including a headband and at least one earcup secured thereto. A microphone is mounted within the earcup for detecting and transducing acoustic pressure within the earcup to a corresponding microphone electronic signal. An electronic signal processing unit is mounted within the earcup and coupled with the microphone for generating an anti-noise signal from the microphone electronic signal. A first speaker is mounted within the earcup for receiving and acoustically reproducing an electronic anti-noise signal from the electronic signal processing unit. A second speaker is mounted within the earcup for receiving and acoustically reproducing an electronic communication signal.
