The Shure Model 527C is a dynamic handheld communications microphone designed for use in a variety of mobile and fixed station applications, including police, transportation, amateur radio and similar applications. The 527C mic offers extremely low sensitivity to hum pickup and low susceptibility to radio-frequency interference. A built-in solid state amplifier permits the use of up to 30 m (100 ft) of unshielded cable.

The modular construction of the 527C allows the cartridge, switch, and cable to be replaced in a matter of minutes, if necessary. The 527C microphone fits naturally and comfortably in the hand and is not adversely affected by heat or humidity.
