Shure SM31FH — Fitness Headset Condenser Microphone
SM31FH Overview
The Shure SM31FH is a cardioid condenser headset microphone purpose-built for fitness instruction environments where perspiration and high-energy movement are constant factors. Its hydrophobic construction repels moisture, protecting internal components and maintaining consistent performance through demanding workout sessions. The microphone connects to Shure bodypack transmitters via a TA4F (TQG) connector, making it a direct replacement option for compatible Shure wireless systems. It is well suited for fitness instructors, aerobics coaches, and presenters who require reliable hands-free audio in high-perspiration settings.
The SM31FH includes a windscreen to reduce breath noise and plosives, and its headset form factor keeps the capsule in consistent position relative to the mouth throughout movement-intensive use.
