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.
