The black B6 Omnidirectional Lavalier Microphone from Countryman connects with plug-in power and audio on left channel via a 3.5mm locking connector. It is a small microphone measuring only 0.1” in diameter.

The changeable protective caps (+0, +4, and +8 dB) provide moisture resistance and allow you to adjust the frequency response to suit different applications or to match other microphones. Each of the 3 omni caps has a different high-frequency response characteristic that controls the amount of crispness or sibilance (response at 15 kHz). With low handling noise and a rugged construction, the B6 Microphone is a suitable choice for theater, broadcast, places of worship, and general lavalier applications.

The omnidirectional mic ships with the +4 dB protective cap attached. This will boost the perceived amount of presence in your sound, while leaving the lower frequencies unchanged.

Note: The B6 lavalier should always be used with a protective cap in place to keep sweat, makeup, and other foreign material out of the microphone. If you experience problems with high-frequency feedback, you should switch to the 0 dB cap.

Nearly Invisible and Unobtrusive

With a diameter of only 0.1" (2.5 mm), the size of a No. 2 pencil lead, the mic capsule virtually disappears when worn. The B6 is easily hidden in the hair, on costumes, or can be taped to a performer's face. The B6 color matches clothing, hair, and skin tones.

Good Sound Quality

It provides high-quality audio with low distortion at SPL up to 140 dB on 48V Phantom Power. The aramid cable combined with the ultra-thin diaphragm ensures low handling noise. The tiny size combined with natural sound pickup make the B6 easy to position for ambient noise and feedback rejection.


The most sensitive (W4, gray band) is for general speaking, such as presentations or public addresses, where the mic is positioned on the chest or lapel.

Rugged and Reliable

The B6 is resistant to makeup, sweat, and moisture when used with the supplied protective caps and is well-suited to use in the hair or on the body. The protective caps can be easily removed for cleaning or replacement when clogged with makeup. The aramid-reinforced cable and rugged alloy construction ensure that the cable provides appreciable tensile and flex strength.

True Color

The color of the mic is precision-matched to theater makeup shades to blend with a wide range of skin tones and clothing.

Water Resistance

The mic is water-sealed so you can use it in the hair or against the skin under hot theater lights without sweat-outs.


Changeable protective caps let you shape the frequency response for different situations or to match other microphones. For different speaking or singing styles, additional caps with up to 140 dB SPL capabilities can be purchased separately.

Cananyone tell me how this performs if you have two speakers close to each other? Is there significant mic bleed between two mics in close proximity (like guest/host interview?) And if used over a PA or speaker system, does the PA bleed into the Mic? Thanks!
Asked by: Brian
Two people can be sitting or standing next to each other and there will be minimal bleed. These mics are omnidirectional, but are finely tuned to supress feedback, if P.A. speakers are placed in front of the talent, facing away. I would recommend this pick-up pattern to allow subjects to move their heads back and forth, without volume fluctuating.

is it possible to connect this to a Tascam DR-05 recorder with an xlr to 3.5mmm jack adapter I want to use it in my pocket as a dual system unit. The B6 doesnt say it need phantom but it doesnt take a battery if there is a way for this to work list what I need please .. thanks.. also I have this version already as well as the Tascam?
Asked by: Steve
The Countryman B6 Omnidirectional Lavalier Microphone with 3-Pin XLR Hardwired Connection will not work into the Tascam Dr-05 with a XLR to 3.5mm adapter. The mic requires phantom power to operate. As an alternative, Countryman makes the EMW lavalier wired for Digital recorders; B&H# COMEMWSFF05B.
