Beta® 53 Subminiature Headworn Condenser Microphone

Overview

Shure model Beta 53 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 its small size, the microphone’s 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.

• Two interchangeable protective caps for response shaping
