WBH54 Headworn Vocal Microphone
The WBH54 (wireless version of the Beta 54) 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.
