Shure BLX14/SM31 Wireless Fitness Headset System with SM31FH Microp...
The Shure BLX14/SM31 delivers reliable analog wireless headset performance tailored for fitness and active vocal applications with professional-quality sound and straightforward setup. The system includes the BLX4 single-channel tabletop receiver, BLX1 bodypack transmitter, and SM31FH cardioid headset microphone featuring moisture-repelling construction that withstands demanding use in high-sweat environments. Operating in the H10 band, it provides up to 300 feet of working range and supports up to 12 compatible systems per band depending on region and environment.
Built for durability and ease of use, the lightweight bodypack transmitter connects via TA4M and offers up to 14 hours of runtime from two AA batteries. One-touch QuickScan locates the best available frequency, while the SM31FH headset provides secure, comfortable wear with a cardioid polar pattern for focused voice pickup and effective off-axis rejection. The receiver features balanced XLR and 1/4-inch outputs for simple integration with mixers and amplifiers.
This wireless headset system excels in fitness classes, aerobics, dance instruction, and other high-energy spoken-word or vocal applications where freedom of movement, sweat resistance, and clear audio are essential.
