Supercardioid Microflex Lavalier Microphones
The Shure Microflex Microphone Series MX 184 bring a new level of sophistication to personal voice reproduction. Like all Microflex family microphones, the MX-184 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.
