TerraBene Black Restored Tech Headworn Voice Megaphone
4.6(15 ratings)TerraBene Black Restored Tech portable megaphone is worn on the head for hands-free voice projection. Its 80mm composite high-pitched crystal magnetic horn and carbon atom lattice graphene diaphragm are designed to reproduce the natural human voice. IC/CVC dual technology, acoustic tuning of the three-tone ratio and frequency shifting reduce whistling.
Based on a teacher using it for 2 classes per day, a full lithium-ion battery charge lasts about 2 weeks. Insert a memory card or U disk to loop lesson recordings. It can be used for teaching, tour guiding, promotions and parties.
