Overview
The Countryman B3 is a compact, professional-grade omnidirectional lavalier microphone, widely trusted in film, television, and live production environments. Known for its incredibly small footprint, the B3 is designed to be easily concealed on talent while still delivering clear, natural-sounding audio. Its omnidirectional pickup pattern ensures consistent sound capture, even when the subject moves or turns their head.

- Choose placement before wardrobe is final, then listen for fabric movement while talent performs the actual blocking.
- Create a small strain-relief loop below the B3 capsule so cable pulls do not reach the microphone.
- Mount the omni close to the sternum or collar line; turning it upside down can help protect the port from sweat.
- Use appropriate concealers and tape on fabric or skin, and never force the cable through a tight costume seam.
