SM58 Vocal Microphone

The Shure SM58® unidirectional (cardioid) dynamic vocal microphone is designed for professional vocal use in live performance, sound reinforcement,
and studio recording. It has a tailored vocal response for a sound which is a world standard for singing or speech. A highly effective, built-in spherical
filter minimizes wind and breath "pop" noise. A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. 

 Rugged construction, a proven shock-mount system, and a steel mesh grille ensure that even with rough handling, the SM58 will perform consistently,
outdoors or indoors.
