The Shure SM58 microphone

The Shure SM58 is a professional cardioid dynamic microphone, commonly used in live vocal applications. Produced since 1966 by Shure Incorporated, it has built a strong reputation among musicians for its durability and sound, and more than four decades later it is still considered the industry standard for live vocal performance microphones.[1][2][3] The SM58 is the best-selling microphone in the world. The SM stands for Studio Microphone.[4]

Like all directional microphones, the SM58 is subject to proximity effect, a low frequency boost when used close to the source. The cardioid response reduces pickup from the side and rear, helping to avoid feedback onstage. It uses the balanced XLR three-pin connection. There are wired (with and without on/off switch) and wireless versions. The SM58 uses an internal shock mount to reduce handling noise.
