The beige CR-8S Cardioid Earworn Microphone from Point Source Audio is designed for high noise applications where more than one microphone is required such as for live performances and recordings. The cardioid pattern of the microphone will pick up sound from one direction, so it can be focused on the sounds of the person wearing the microphone. The unit features a 4mm diameter microphone element that can be positioned at the corner of the mouth to maintain an unobtrusive appearance.
