Find the Fitness Headset Microphones and Transmitters that are compatible with your system. Or add more to your rotation! Wireless Headset Microphones for fitness instruction come in a variety of styles. Durability and comfort are important considerations when choosing replacement mics, but you are limited to the options that are compatible with your receiver. Most receivers are compatible with only one model of transmitter.
Replacement Transmitters
Belt pack transmitters are available separately from packaged systems for most current models of wireless microphone systems. A few headset microphone systems, such as the Samson AirLine series and the Fitness Audio Mini-TX, have the transmitters attached directly to the headset microphone. Please make sure you know which frequency (or group of frequencies) your receiver operates on. Questions? Contact a fitness microphone expert at AV Now today.
