SHURE SM31FH-TQG หูฟัง Wireless headset microphone featuring moisture-repelling hydrophobic construction for use in fitness instruction.
The Shure SM31FH adds hydrophobic materials to the industry-standard, road-tested Shure SM family in a rugged and durable cardioid condenser microphone. TA4F 4-pin connectors make it a viable replacement for any existing Shure wireless headset system. The moisture-repelling cartridge housing protects the microphone and ensures a long lifetime of use, all but eliminating the need to frequently replace typical headsets.
