Used Countryman B6 Omnidirectional Lavalier Mic with 3.5mm Non-locking Connector 1/8" (3.5mm) Mini Connector, W6 (Blue Band) Low Gain for Head Miking with Powerful Vocals, Black

Only one tenth of an inch in diameter, the B6 is the smallest lavalier in the world and outperforms microphones many times its size. The swappable protective caps provide moisture resistance and color options and let you shape the frequency response to suit different applications or to match other microphones. With exceptionally low handling noise and rugged construction, the B6 is the ideal choice for theater, broadcast, churches and general lavalier applications.

Unobtrusive
Smaller than the cable of other lavaliers, the B6 is easily hidden in hair or on costumes or taped to a performer's face. The B6 comes in five colors to match clothing, hair and skin tones or use a felt tip marker to color the white caps for near-perfect conceal ability. Never suffer the hassle and degraded sound quality of underclothing miking again

Exceptional Sound Quality
The highest-quality audio available in a lavalier mic. Low distortion at SPL 130 dB on 48 V Phantom Power. The Aramid cable and ultrathin 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.

Rugged and Reliable
The B6 is exceptionally resistant to makeup, sweat and moisture when used with the supplied protective caps and is well-suited to use 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
Swappable protective caps let you shape the frequency response for different situations or to match other microphones. Versions available for different speaking or singing styles, with 140 dB SPL capability.

Protective Cap
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. The three omni caps each have a different high-frequency response characteristic that controls the amount of "crispness" or "sibilance" (response at 15 kHz). To identify caps, compare size to the drawings. The omni ships with the +4 dB protective cap fitted to the mic. This will boost the perceived amount of presence in your sound, while leaving the lower frequencies unchanged. If you experience problems with high-frequency feedback, you should switch to the 0 dB cap.

Sensitivity
The least sensitive mic (W6, blue band) with the highest overload sound level is a good choice for instrument applications, opera or where the microphone will be positioned very near the mouth.

Applications

Hair Mic
The B6 is very popular as an ultra miniature hair microphone. This placement provides good gain before feedback and natural sound that doesn't change when the head moves. (Microphone extended here for visibility)

Behind a Button
Positioned in the knot of a tie or behind a shirt button, the B6 delivers flawless audio and hides in plain sight. When placed completely under clothing use the +4 dB or +8 dB protective cap to boost high frequencies.

Attached to Eyeglasses
The B6 is also popular on stage attached to glasses. Placement on eyeglasses with O-rings or tape is secure, discreet and a convenient alternative to hair miking.
