- Addressing groups of people discreetly without sound reinforcement is difficult, especially when conducting tours of factories, places of interest and conferences. High ambient noise levels and speaking outdoors present special problems making it essential to use an effective communication system.
OKAYO’s wireless tour guide system, designed to be easy to use, lightweight and durable. OKAYO wireless tour guide system allows the guide’s voice to be clearly heard by each person on the tour equipped with a personal receiver. This system effectively eliminated the listening challenge of background noise, distance and reverberation.
