The Shure SM58S Vocal Microphone features a unidirectional (cardioid) dynamic vocal design, well suited for professional vocal use in live performances, sound reinforcement, and studio recording. A built-in spherical filter minimizes wind and breath "pop" noise, while the cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The microphone offers durable construction, a high-quality, internal shock-mount system, and a steel mesh grille for withstanding rough handling. The SM58S is designed to perform consistently both outdoors and indoors, and when used for singing or speech applications. The microphone features an integrated on/off switch.
