Shure MX183 Microflex Series Wired Lavalier Microphone (Omnidirectional)

Shure Microflex™ Lavalier microphones bring a new level of sophistication to personal voice reproduction. Like all Shure Microflex family microphones, the Lavaliers use Shure's interchangeable condenser cartridges, available in cardioid, supercardioid or omnidirectional polar patterns. Compatible with all Shure wireless bodypack transmitters, their high sensitivity and wide frequency response guarantee great sound.
