Product Description

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. 

  • Condenser cartridge for studio quality sound

  • Tailored frequency response for a clear reproduction of vocals

  • Rugged construction withstands the rigors of touring sound

  • Cardioid polar pattern minimizes unwanted background noise

  • Excellent choice for stage monitors and personal monitors

  • Built-in three-point shock mount minimizes handling noise

  • Two-stage "pop" filter reduces wind and breath noise
