Countryman B6CAPT-0

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 15kHz).

The omni ships with the +4dB protective cap fitted to the mic. We have found that this cap's frequency response meets the needs of the majority of users, providing a slightly increased response in the 15kHz range. 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 0dB cap.
