The black B3 Omnidirectional Lavalier Mic, Standard Sens, with 3.5mm Locking Connector for Sony Wireless Transmitters from Countryman is a water-resistant, miniature lavalier microphone for capturing high-quality audio. It can be used in a variety of applications such as a tie-clip lavalier in interviews, a hair-hidden mic for drama, a water-resistant mic for water sports and hurricane reporting, or simply a small mic to hide in a prop flower vase.

The capsule is resistant to moisture, which allows for placement in the hair or on bare skin, and its omnidirectional polar pattern minimises handling noise, wind noise, and plosives (popping). Furthermore, a variety of skin-matching colours are available. The B3's cable terminates to a 3.5 mm locking connector for direct connection to a Sony WRT-805A, UWP Series, UTX-B1, UTX-B2, or UTX-B03 wireless bodypack transmitter. Additionally, a carrying case, two cable clips, a windscreen, and three protective caps are also included.



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 colours to match clothing, hair, and skin tones. Use a felt tip marker to colour the white caps for near-perfect concealability. Never suffer the hassle and degraded sound quality of under-clothing miking again.

Rugged and Reliable

The B3 is 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.

Refined Sound Quality

The B3 provides high-quality audio with low distortion at SPL up to 150 dB on 48V phantom power. The aramid cable and thin diaphragm combine to offer low handling noise. The flat frequency response accurately captures voice or instruments, and the small size makes the B3 easy to position for ambient noise and feedback rejection.


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.


Standard, for most uses.
