The UHF-5900-BP Headset Mic and Bodypack Transmitter from VocoPro is designed to be used as an optional headset mic and bodypack transmitter with UHF-5900 wireless systems. It operates on the FCC compliant 600 MHz range. The headset has a flexible mic neck that allows you to adjust it for the most comfortable fit.
