COUNTRYMAN ASSOCIATES INC
B3 OMNIDIRECTIONAL
LAVALIER MICROPHONE
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 hidden hair mic for drama,
a water-resistant mic for reality TV, 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.
And that’s exactly why we made the B3 so rugged. The cable is protected from
stretching by a rugged aramid core, and the mic’s protective caps are extremely
resistant to water, sweat, and makeup.
You’d never expect such a mic to be so affordable, making the B3 one of the
highest-value audio investments in your kit.
Unobtrusive
Looks great when you want to see it,
virtually disappears when you don’t.
The B3 is easily hidden in hair or on
costumes, with five colors to match
clothing, hair, and skin tones. Use a
felt tip marker to color the white caps
for near-perfect concealability. Never
suffer the hassle and degraded sound
quality of under-clothing miking again.
Exceptional Sound Quality
The B3 provides the highest-quality
audio available in a lavalier mic, with
low distortion at SPL up to 150 dB
on 48 V Phantom Power. The aramid
cable and ultra-thin diaphragm
combine to set a new standard for low
handling noise. The ultra flat frequency
response accurately captures voice or
instruments, and the small size makes
the B3 easy to position for ambient
noise and feedback rejection.

Rugged and Reliable
The B3 is exceptionally resistant to
makeup, sweat, and moisture when
used with the supplied protective
caps, and works well in hair or on the
body. The protective caps are easily
removed for cleaning or replacement,
and the Aramid-reinforced cable gives
it world-class survivability.
Versatile
Changeable protective caps let you
shape the frequency response for
different situations or to match other
microphones. Versions are available
for different speaking or singing styles,
with high overload capability for
recording instruments.
