Point Source Audio CO-3 / CO-3-KIT

CO-3 Earset Microphone


Model No: CO-3 / KIT

The CO-3 Microphone is our entry-level earworn 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 omnidirectional polar pattern which allows a full 360 degree pick up of sound providing a natural blend of voice and ambience.

Improved Speech Intelligibility

The design of the CO-3 earworn microphone lends itself to reduced speech produced “popping sounds” and voice overloads in close mic applications and the convenient placement near the mouth greatly reduces noise from wind and clothing.

Consistent Fit Everytime

The slim rigid boom has a fixed length and ear-loop is designed to mount onto the left ear. The entire structure is designed to be unobtrusive and low-profile.
