Our 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 lavalier.

And that's exactly why we 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!

Supplied with set of two tie clips (black and white), wind screen, three HF response control protective caps, and carrying case.


All-purpose, rugged, affordable lavalier that's easy to hide in clothing, hair or props
