Making the jump to wireless should be liberating, not challenging. 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 PGA31 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 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.

Shure BLX14/PGA31 Specifications:
System
Working Range: 91 m (300 ft) Line of Sight (Actual range depends on RF signal absorption, reflection and interference.)
Audio Frequency Response: 50 to 15,000 Hz (Dependent on microphone type)
Total Harmonic Distortion (Ref. ±33 kHz deviation with 1 kHz tone): 0.5%, typical
