Shure Microphone, Shure  PG58-QTR Handheld Dynamic 1/4 Jack 

• Tailored frequency response is smooth and extended. Tuned specifically for vocal applications.
• Cardioid polar pattern picks up the most sound from in front of the microphone and some sound from the sides. Less susceptible to feedback in high volume settings.
• Dynamic cartridge has a simple, rugged coil. Handles extreme volume levels without distortion.
• Cartridge includes a neodymium magnet for high output level.
• Internal shock mount for reduced handling noise.
• Durable metal construction.
• On/off switch for onstage control.
