The Shure SM87 now features a new design and has been renamed the SM87A. In response to user requests, Shure has redesigned this microphone by just slightly thickening the handle for a more comfortable feel. In addition, the SM87A now includes the A25D break-resistant swivel adapter.
A favorite choice of the world's top entertainers, the SM87A condenser microphone features a smooth frequency response that's specifically tailored for warm, rich, vocal reproduction.
