The SM-2-MN Dual-Sided Earset Microphone for Recorders and Wireless 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 dual earclips easily conform to your ears and hold 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 clearly from all directions, so if you turn your head, there is no loss of volume. 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 3.5mm mini-jack connector, it is compatible with portable recorders and wireless bodypack transmitters.
