What is the PGA31 Headset best suited to?

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.

Wearable wireframe headset fits securely for multi-instrumentalists and active performers

Permanently-charged electret condenser element for detailed, crisp vocals

Unidirectional (cardioid) polar pattern rejects unwanted noise for improved sound quality and higher gain-before-feedback
