The black E6i (4-Pin Hirose) from Countryman is a miniature, omnidirectional, earset condenser microphone designed for accurate voice reproduction (speaking and singing) and near-invisible appearance in theater, concerts, lectures, houses or worship, and more. It features a water- and wind-resistant capsule that delivers a 20 Hz to 20 kHz frequency response. The omnidirectional polar pattern picks up sound from all directions and should be used when feedback is not common.
