Shure - Microphones - Beta 54 Headworn Microphone

Beta 54 Headworn Microphone

The Shure Beta 54 is a subminiature, electret condenser headworn microphone. It provides uncompromised sound quality and reliability with minimal visibility in applications such as broadcast, theater, and touring. Despite the 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.

A wireless version is available as the WBH54.

The Beta headworn vocal microphone features a smooth, tailored response for a warm, natural sound. Its supercardioid design provides maximum gain-before-feedback and ambient rejection. Supercardioid, Condenser.

Supercardioid polar pattern provides maximum gain-before-feedback and ambient rejection
Extended frequency response tailored for vocal performances
Able to handle extremely high sound pressure levels (SPL)
Snap-fit foam windscreens stay in place during intensive movement
Available with an in-line preamp or with a TA4F connector for wireless applications
WBH54: Choice of black or tan finish to suit your performance environment
