Only one tenth of an inch in diameter, the B6 is the smallest lavalier in the world and outperforms microphones many times its size. The changeable protective caps provide moisture resistance and color options and let you shape the frequency response to suit different applications or to match other microphones. With exceptionally low handling noise and rugged construction, the B6 is the ideal choice for theater, broadcast, churches, and general lavalier applications. 


The B6 Lavalier is supplied with:

  • Carrying case
  • Black and white cable clips
  • Windscreen
  • Protective caps (+0, +4, and +8 dB)

Nearly invisible

With a diameter of only 0.1” (2.5 mm) — the size of a No. 2 pencil lead — the mic capsule virtually disappears when worn.

Rugged cable

Aramid strength members and engineered alloys ensure that our cables provide extreme tensile and flex strength.

True colors

Our colors are precision-matched to theatre makeup shades to blend with a wide range of skin tones and clothing.

Water resistance

Our mics are water-sealed so you can use them in the hair or against the skin under hot theater lights without "sweat-outs".
