Our B3 is essential to any well-stocked pro audio toolkit: it captures the highest-quality audio available in a lavalier mic, with field-selectable high-frequency response caps and extremely low handling noise. Whether you need a tie-clip lavalier 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.

The B3 Lavalier is supplied with:

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

High overload

At sound pressure levels approaching the pain threshold, our mics still won't distort. That's why they're favorites for rock bands and opera singers alike.

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".
