Countryman BW4FF05TSL Omni Wireless Lavalier Microphone (For Shure)


SKU: COUNTRYB3W4FF05TSL Categories: , Tag:


The B3 omnidirectional lavalier microphone by Countryman is one of the best small-format microphones out there. It’s just what you need for interviews, dramatic productions, broadcasts, and more. Small enough to disappear in clothing, the B3 still provides the sensitivity needed to clearly pick up your voice. A set of three interchangeable capsules allows you to select the B3’s sensitivity, and both a black and a white clothing clip allow you to place the B3 wherever you like. An included windscreen and naturally low handling noise also keep your sound free of unwanted sound. This version of the B3 is outfitted with a TA4F connector and is compatible with Shure wireless bodypacks.


Swappable protective caps let you shape the frequency response for different situations or to match other microphones. Detachable connectors allow you to interface to hundreds of wireless transmitters, recorders, and other equipment. Versions available for different speaking or singing styles, with up to 150 dB SPL capability.

Exceptional Sound Quality

The highest-quality audio available in a lavalier mic. Low distortion at SPL up to 140 dB on 48 V Phantom Power. The aramid cable and ultra-thin diaphragm combine to set a new standard for low handling noise. The
tiny size and natural sound pickup make the B6 easy to position for ambient noise and feedback rejection.
