They're no bigger than a paper clip unless you consider the sound they produce. The 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's a Microflex Lavalier that's right for your job.

The Microflex Lavaliers are completely compatible with all Shure Wireless transmitters, and their high sensitivity and wide frequency response guarantee great sound with a minimum of RF interference or electromagnetic hum. Plus, each Microflex Lavalier features the same Shure quality sound that has become an industry standard. But don't take our word for it. Just listen, and you'll hear how the best solution just got better.
