The ESM-1-TA4 Single-Sided Earset Microphone for Shure Transmitters from Polsen is a low-profile, lightweight earset microphone that is designed to deliver accurate and natural-sounding speech and vocals. The miniature 3mm microphone is optimized for speech and is mounted on a flexible, adjustable boom for precise mic placement. The single-sided earclip easily conforms to your ear and holds the mic in place for active applications such as fitness, mobile journalism, house of worship, and more.
The microphone's omnidirectional polar pattern is designed to pick up speech from all directions; even when the mic isn't directly in front of your mouth, the sound is still present and clear. Additionally, for theatrical and live presentations, this earset's low profile won't obstruct a user's face, distract an audience, or cast an unwanted shadow. Built with a cable that terminates to a TA4F connector, it is compatible with Shure wireless bodypack transmitters.
