More about the SM31FH

Built for durability, the SM31FH’s lightweight, low-profile wireframe headset fits securely and comfortably—ideal for fitness and aerobics instructors who need to keep their focus on their students, not whether their microphone is going to stay put. The flexible gooseneck lets you adjust the placement so it perfectly captures your vocals, while the cardioid polar pattern allows for enhanced isolation from surrounding sound sources.

The SM31FH is compatible with Shure bodypack systems and can be used to replace TA4F 4-pin (TQG) connected microphones. It comes bundled with BLX and GLX-D wireless systems.

The SM31FH comes with a windscreen to protect your audio against plosives, heavy breathing, and wind noise—resulting in a clean, intelligible sound even when the speaker or surrounding environment is most active.
