An earset assembly including a first earpiece, a second earpiece, and an electrical circuit. The first earpiece includes an internal microphone to capture speech of a user and an internal speaker, and is positionable with respect to a first ear of the user so that the internal microphone detects the speech from the first ear of the user. The second earpiece includes an internal speaker, and is positionable with respect to a second ear of the user. The electrical circuit operatively connects the internal microphone and the internal speakers to a communication device. In an audio listening state, the electrical circuit is configured to operatively couple the internal speakers respectively to first and second audio ports of the communication device for outputting stereo audio content with the speakers, and the internal microphone is switched to an off state. In a communication state, the electrical circuit is configured to switch the internal speaker of the first earpiece to an off state, switch the internal microphone of the first earpiece to an on state for voice communication and operatively couple the internal microphone to a microphone port of the communication device, and maintain the operative coupling of the internal speaker of the second earpiece to the respective audio port for use in the voice communication.
