Shure SM7B Cardioid Dynamic Vocal Microphone

The SM7B dynamic microphone has a smooth, flat, wide-range frequency response appropriate for music and speech in all professional audio applications. It features excellent shielding against electromagnetic hum generated by computer monitors, neon lights, and other electrical devices. The SM7B has been updated from earlier models with an improved bracket design that offers greater stability. In addition to its standard windscreen, it also includes the A7WS windscreen for close-talk applications.
