Point Source Audio's CO-3 Series Microphone is their entry-level ear-worn microphone designed for speech reinforcement for church liturgy, lecturing, and other applications that require good quality vocal pick up in a hands-free environment.  It has an omni-directional polar pattern which allows a full 360 degree pick up of sound providing a natural blend of voice and ambience.  The design of the CO-3 series lends itself to reduced speech produced "popping sounds" and voice overloads in close mic applications, and is less susceptible to wind and clothing noise than lavaliere-style microphones.  Its distinguishing clarity in close talk operation and excellent gain before feedback make it suitable for applications where higher degrees of speech intelligibility are desired.
