The legendary Shure SM58 Vocal Microphone is designed for professional vocal use in live performance, sound reinforcement, and studio recording. 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.FeaturesFrequency response tailored for vocals, with brightened midrange and bass rolloffUniform cardioid pickup pattern isolates the main sound source and minimizes background noisePneumatic shock-mount system cuts down handling noiseEffective, built-in spherical wind and pop filterSupplied with break-resistant stand adapter which rotates 180 degreesLegendary Shure quality, ruggedness and reliabilityCardioid (unidirectional) dynamicFrequency response: 50 to 15,000 HzReplacement cartridge: R59.
