The legendary Shure SM58 vocal microphone is designed for professional vocal use in live performance, sound reinforcement and studio recording. Its tailored vocal response for sound is a world standard for singing or speech. A highly effective, built-in spherical filter minimizes wind and breath "pop" noise. A unidirectional (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.
