Shure Beta 87A

The Beta 87 has consistently been a top choice of performers and audio technicians around the world due to its superb accuracy and detail, and rich vocal production. This long-standing favorite now features a new design and has been renamed the Beta 87A.

In response to user requests, Shure has redesigned this microphone by just slightly thickening the handle for a more comfortable feel when hand-held. In addition, the Beta 87A now includes the A25D break-resistant swivel adapter.

The Beta 87A condenser microphone leads the field for studio-quality sound in live performance vocals.
