The Shure SM58 is a unidirectional (cardioid) dynamic vocal microphone for professional vocal use in sound reinforcement and studio recording. 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. The SM58 Microphone has a tailored vocal response for a sound which is a world standard. Rugged construction, a proven shockmount system, and a steel-mesh grille ensure that even with rough handling, the SM58 Vocal Microphone will perform consistently. Outdoors or indoors, singing or speech, the Shure SM58 is the overwhelming choice of professionals worldwide. How It Works?. Made to handle voice with clarity and care, the uniform cardioid polar pattern reproduces every note as it was intended with reduced background noise. On any stage—from the club show to the stadium—the Shure SM58 Microphone delivers warm, crisp sound time after time. Uniform Cardioid Pick-Up Pattern. Uniform cardioid pick-up pattern for maximum gain before feedback and excellent rejection of off-axis sound. Pneumatic Shock Mount. Handling noise gets absorbed by an advanced pneumatic shock mount system, keeping the sound free of vibration. Screen Out Unwanted Air. When wind and plosives try to take over, the spherical mesh grille and effective built-in pop filter keep them out of the mix. Rugged Construction. The mic’s durable construction and the break-resistant mic clip keep the SM58 Microphone going strong through the toughest performances.
