Shure 55SH Microphone

An unmistakable stage icon for 70 years, the Shure 55SH Series II Unidyne® Vocal Microphone features a signature satin chrome-plated die-cast casing for pure vintage look and feel with modern acoustic components to meet today's performance standards. This microphone is excellent for vocal pickup with its characteristic Shure presence peak.

The 55SH Series II microphone has a cardioid (unidirectional) polar pickup pattern that minimizes sound pickup from the rear of the microphone. This allows the Model 55SH Series II to be used in close proximity to loudspeakers without creating feedback problems, and it can perform under adverse acoustic conditions where omnidirectional microphones cannot.
