Wireless headset tour guide devices are portable short-range wireless devices used to transmit an audio message. Our tour guide speaks into a radio microphone transmitter and the tourists use lightweight receivers (50 gram) with their individual headset to hear the message. It means that you never lose any spoken words from our tour guide even in the noisy environment or long distance. Furthermore, it helps to avoid disturbing anyone as the tour guide can speak softly but you can hear it easily and clearly.
