Shure SM86

The Shure SM86 is a unidirectional (cardioid) condenser vocal microphone for professional use in live performance. An extremely rugged microphone, the SM86 withstands the rigors of touring while delivering a clear, studio-quality sound.

A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The built-in three-point shock mount minimizes handling noise, and a two-stage pop filter reduces wind and breath "pop" noise.
