Professional miniature lavalier microphone with 3.5mm connector


The Countryman B3 Omnidirectional Microphone is a miniature lavalier microphone for general public speaking, interviews, stage performances, video and film shoots, houses-of-worship applications and much more.

The capsule measures 0.2" in diameter and is resistant to moisture which allows for placement in hair and on bare skin. In addition, its omnidirectional polar pattern minimizes handling noise, wind noise and plosives (popping).

A wide variety of colors and connections are available for use with various wireless transmitters. This version is black and features a Mini 1/8" (3.5mm) Locking for Sennheiser wireless transmitters.
