Countryman's B3 is essential to any well-stocked pro audio toolkit. For starters, the B3 captures the highest-quality audio available in a lavalier mic, with field-selectable HF response caps and extremely low handling noise. Whether you need a tie-clip lav for an interview, a hair-hidden mic for drama, a water-resistant mic for water sports or hurricane reporting, or simply a small mic to hide in a prop flower vase, you'll never run out of applications for Countryman's B3 omnidirectional lavalier.

And that's exactly why they made the B3 so rugged. Kevlar protects its cable from excessive weight and stretching, and the mic's protective caps are extremely resistant to water, sweat, and makeup. You'd never expect such a mic to be so affordable, making the B3 one of the highest-value audio investments in your kit!

This particular model is the B3W4FF05LSL, which is compatible with the following Shure product: AXT100+, BLX1, FP1, GLXD1, PG1, PGX1, PGXD1, QLXD1, SLX1, UC1, ULX1, ULXD1, UR1, and UR1M. This mic has standard gain for most uses and comes in Light Beige.
