Abstract: A communication headset system (1) for connecting to a two-way communication device (10). The communication headset system (1) comprising an earphone (15) with a speaker (2) for receiving a speaker signal (3) and converting it into speaker sound, a voice microphone (4) for receiving a user's voice and converting it into a voice signal (5). The communication headset system (1) further comprises an ambient microphone (6), arranged at a distance from the voice microphone (4), for receiving ambient sound and converting it into an ambient sound signal (7), and a control circuit (8) for receiving the ambient sound signal (7) and an input signal (12) from the telecommunication device (10), and for transmitting the speaker signal (3) to the speaker (2). The control circuit (8) comprises a switching circuit (9) for switching the headset system between an ambient mode in which the speaker signal (3) comprises the ambient sound signal (7) and not the input signal (12) and a communication mode in which the speaker signal (3) comprises the input signal (12) and not the ambient sound signal (7).
