Shure BLX14/PGA31 Wireless Cardioid Headset Microphone System (H11: 572 to 596 MHz)

The Shure BLX14/P31-H11 is a wireless headset microphone system that arrives as a complete package for performers, presenters, and instructors who want to keep both hands free and still be heard clearly. It combines the lightweight PGA31 cardioid headset microphone with the BLX1 bodypack transmitter and the BLX4 tabletop receiver, giving you a straightforward path to dependable Shure sound without the clutter of cables.

Setup is intentionally simple. Press the QuickScan button on the receiver and the system finds a clear frequency in seconds, so you spend less time scrolling through menus and more time focusing on the event. Once connected, you can move as far as 300 feet from the receiver while maintaining a solid signal. The BLX1 bodypack runs for up to 14 hours on two standard AA batteries, which means you can cover an entire workday, worship service, or double-header gig without swapping power.

The PGA31 headset uses a cardioid pickup pattern that helps your voice cut through while reducing feedback and crowd noise. Its flexible boom and secure headband fit comfortably during active use, making it a smart choice for fitness classes, stage performances, corporate training sessions, or tour guiding. The BLX4 receiver sits neatly on a podium, equipment rack, or front-of-house table and offers balanced XLR and unbalanced 1/4-inch outputs for easy connection to mixers, powered speakers, or recording devices.

Because the system operates in the H11 band from 572 to 596 MHz, you can run up to 12 compatible BLX systems at the same time when you need multiple microphones for a panel discussion or small theater production. Rugged construction throughout reflects Shure’s live-sound heritage, so the components stand up to travel and repeated use.
