Shure

Description

The rugged and durable SM31FH is a cardioid condenser microphone constructed with hydrophobic materials that make it ideal for true performance in fitness instruction applications. The moisture-repellent cartridge housing ensures a long product life by protecting the microphone from the corrosion damage that causes typical fitness instruction headsets to fail. The SM31FH features TA4F 4-pin (TQG) connectors that make it a viable replacement for any Shure wireless headset system.
