The Shure Beta 54TM is a subminiature, electret condenser head worn microphone. It provides uncompromised sound quality and reliability with minimal visibility in applications such as broadcast, theater, and touring. Despite their small size, the condenser element delivers full, clear, and natural reproduction of speech and vocals.
The microphone features a durable, low-profile wire frame headband which is fully adjustable for stability and comfort. A plastic carrying case protects the microphone and its accessories.
