SM58 Cardioid Dynamic Vocal Microphone
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 indoor
