Shure MX184

Microflex™ Lavalier microphones bring a new level of sophistication to personal voice reproduction. Like all 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.
