Countryman B2D Directional Lavalier

The B2D mic is easily the smallest directional lavalier in the world, with the next smallest mic being more than twice its size. Combined with exceptional sound quality and isolation, this tiny package opens up a new set of miking options that were previously unavailable. The tight hypercardioid pattern gives the B2D an extra 6-10 dB of headroom compared to an omni lav, meaning less problems with feedback, ambient noise, room rumble, and phase cancellations with multiple mics.

  • Easily hidden in hair/costumes or taped on performers' faces in film, theater and broadcast.
  • Well-suited for news anchors, interviews, lecturers, churches, schools and general lavalier applications.
  • Tight hypercardioid pattern rejects surrounding noise 6-10 dB better on average than an omnidirectional lavalier.
  • Low distortion at SPL up to 140dB (W6 sensitivity version).
  • Super-rugged cable boasts greater than 45 lbs break strength.
  • Accurate frequency response tuned for excellent speech intelligibility in chest and head worn applications.
  • Detachable cables allow swapping from one wireless transmitter to another, or to an XLR input on the mixing console.
Style & Comfort
  • Smaller than the cable of other lavaliers.
  • Comes is five colors to blend with clothing and skin tones.
  • Easily hides in plain sight by swapping colored caps to match button hole, sweater weave or skin tone. Use a felt-tip marker to color the white caps to get an exceptional match.
  • Built to withstand perspiration and makeup, for use in hair or on the body.
  • Protective cap is easily removed for cleaning or replacement when clogged with makeup.
  • Aramid-reinforced cable withstands heavy use.
