Countryman B3 Omnidirectional Lavalier Mic

Exceptional audio quality, low handling noise, extreme water-resistance, and excellent durability.

Please note that the 2 different options for the sensitivity available on the B3 are the W4 standard sensitivity for most situations, apart from higher sound pressure (SPL)the W5 version or red band is for higher sound pressure and theatre head miking.

The Countryman 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 microphones as standard are unterminated/bare end wire. If you would like your B3 custom terminated, please allow a 2-3 day turn-around for our excellent custom termination service. If you need it terminated urgently, please contact our sales team for options.

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, Countryman 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 the cables provide extreme tensile and flex strength
  • True colours. Colours are precision-matched to theatre makeup shades to blend with a wide range of skin tones and clothing.
  • Water resistance. Countryman mics are water-sealed so you can use them in the hair or against the skin under hot theater lights without "sweat-outs".
