Audibax Missouri Free Head UHF - UHF Wireless Headset Microphone with USB-C Receiver (4 frequencies, up to 50m)

The Audibax Missouri Free Head UHF is a compact and easy-to-use wireless system that combines a bodypack transmitter with a headset microphone (also includes a lavalier microphone) and a rechargeable receiver with a 6.35 mm jack output. Designed for classrooms, lectures, fitness classes, tour guides, and outdoor events, it operates in the UHF 520–580 MHz band with four selectable frequencies to avoid interference. The digital transmission architecture improves stability and audio quality, while independent power for each component ensures portability: the bodypack transmitter runs on two AA batteries (up to 30 hours ) and the receiver has an integrated battery with USB-C charging (typical battery life 7–8 hours ). The effective range is up to 50 m under favorable conditions, and synchronization is very simple: connect the receiver to the device, turn it on, scan, and you're ready to go.
