The PGA31 cardioid headset condenser microphone offers clear and reliable hands-free audio at an affordable price. The unidirectional (cardioid) pickup pattern provides excellent off-axis rejection for higher gain-before-feedback when using a stage monitor. The PGA31 is a permanently-biased electret condenser mic, which means it has a charged backplate in manufacturing, eliminating the need for an external charge. For general, speaking and performance use, this condenser mic has a comfortable design and secure fit with a flexible gooseneck for increased mobility and optimized mobility.

With the PG ALTA™ Microphone family, Shure continues its 90-year tradition of manufacturing audio products of the highest quality and construction.Featuring a sleek black metallic industrial design and cardioid polar patterns that reduce feedback and background noise, the PG ALTA family delivers rock-solid sound and reliability that sets the bar for accessible, professional-caliber gear for performance and recording.
