Great lav mic with good versatility for narrative or docu style works. Comes with all you need and a nice carrying case. Connects flawlessly with my lectro 400 series.

Countryman's 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 they 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. 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.

Protective Cap
The B3 Lavalier should always be used with a protective cap in place to keep sweat, makeup and other foreign material out of the microphone. The caps make the B3 very water resistant. The three omni caps each have a different high-frequency response characteristic that controls the amount of "crispness" or "sibilance" (response at 15 kHz). The B3 ships with the +0 dB (Flat) protective cap fitted to the mic. Switch to the +4 dB or +8 dB cap to 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 less sensitive version (W5, red band) is ideal for instruments or as a hair mic in theater

Applications

Installation Mic
The protective cap of the B3 shields it from moisture and dust and reduces vibrations, making it an excellent installation microphone.

Concealed in Clothing
Positioned in the knot of a tie or behind a shirt button, the B3 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.
