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. That means you can be sure there is a Microflex Lavalier that's right for your application.  Compatible with all Shure wireless bodypack transmitters, their high sensitivity and wide frequency response guarantee great sound.
