The PGA31 Headset Condenser Microphone is an affordable wireless cardioid condenser headset microphone that delivers reliable sound quality for speech and live vocal performance applications. It offers a secure fit for hands-free operation in any situation. Its unidirectional cardioid polar pattern provides excellent off-axis rejection for higher gain-before-feedback when using a stage monitor. It features TA4F 4-pin connectors that make it a viable replacement for any Shure wireless headset system.
