The Point Source Audio CO‑3 with TA4F connector is a single‑ear, omnidirectional earworn microphone designed for clear, hands‑free speech reinforcement in presentations, worship services, and other spoken‑word settings. It uses a back‑electret condenser element with a 50 Hz–16 kHz response and is worn on the left ear with a fixed, low‑profile boom that keeps placement consistent. The omnidirectional capsule provides a natural sound and reduces noise from wind, clothing, and breath pops, while the TA4F termination makes it compatible with Shure wireless transmitters. Lightweight and unobtrusive at only 0.28 oz, the CO‑3 offers up to 116 dB SPL handling and a 3'11" cable, making it a practical option for reliable, discreet speech pickup
