Moisture Resistant Frequency Caps Three frequency response altering caps provide flat, bright and very bright high-frequency enhancement. In addition the caps are resistant to moisture caused by perspiration, make-up, humidity, etc. Omnidirectional Polar Pattern The omnidirectional polar pattern is most effective in minimizing wind noise, plosives (popping) and handling noise. Sensitivity Optimized for Strong Vocals The B3 is available in two sensitivities. This version is optimized to accurately capture strong audio signals without peak distortion and noise, also providing optimum results when placed in hair for theater applications.
