Wireless System with Cardioid Condenser Headset Mic - 

Shure BLX Wireless Systems combine professional quality sound with simple setup and an intuitive interface for performance you can trust right out of the box. Precision built and available in a variety of handheld, lavalier, instrument and headset configurations, it’s the most accessible way to own the stage. The model BLX14/PGA31 contains a reliable SM31 headset microphone for vocal performance and spoken word applications. This model contains a rugged, comfortable head-worn microphone with increased moistureresistance for active speech and fitness applications. The SM31 performance headset microphone for general, speaking and performance use is a permanently-biased electret condenser microphone. Engineered to provide maximum versatility and reliable performance in a wide array of conditions at an affordable price, the SM31 is compatible with any Shure wireless bodypack systems with TA4F (TQG) connectors. Available as an included option for many systems, it also makes a viable replacement option for use in existing systems. The wearable design offers improved comfort and a secure fit for hands-free operation in any situation, while the unidirectional (cardioid) pickup pattern provides excellent off-axis rejection for higher gain-before-feedback when using a stage monitor.
