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.
