A portable system for enhancing communication between at least two users in proximity to each other includes first and second noise-reducing headsets, each headset including an electroacoustic transducer for providing sound to a respective user's ear and a voice microphone for detecting sound of the respective user's voice and providing a microphone input signal. A first electronic device integral to the first headset and in communication with the second headset generates a first side-tone signal based on the microphone input signal from the first headset, generates a first voice output signal based on the microphone input signal from the first headset, combines the first side-tone signal with a first far-end voice signal associated with the second headset to generate a first combined output signal, and provides the first combined output signal to the first headset for output by the first headset's electroacoustic transducer.
