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.

About Dynamic Microphones at Sound Productions
If you’re looking for an all-purpose, heavy-duty microphone, look no further than a dynamic microphone. Equally outstanding in both the studio and live on stage, dynamic mics are an affordable, versatile, and classic option for nearly every miking application. Popular uses include live performances, studio recordings, man-on-the-street style interviews, as well as podcasts that aim for a professional “radio voice” polish.
Dynamic microphones work using a coil attached to a magnet. When sound waves cause the coil to vibrate up and down against the magnet, an electromagnetic current is induced; in simple terms, this turns the sound into an electronic signal to be channeled into a recorded version or—in the case of live sound—into a speaker to distribute the sound to the audience.
