The ESM-1-MN Single-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 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 3.5mm connector, it is compatible with recorders and wireless bodypack transmitters.
For Wireless Systems
The ESM-1-MN features a 3.5mm connector for compatibility with recorders and wireless transmitters. The 47" cable is long enough that it won't restrict your movements while speaking or performing.
For Speech and Vocals
The earset microphone is optimized for capturing clear, natural-speech, and vocals. When recording in a large venue with a large audience, the omnidirectional polar pattern allows you to be heard loud and clear.
Omnidirectional Polar Pattern
The omnidirectional polar pattern is designed to pick up your voice if the microphone is in front of you or off axis. It ensures a low sensitivity to vocal pops or plosives and sounds natural and accurate, and even if the mic is very close to your mouth, it won't sound deep or boomy.
Compact and Lightweight
There isn't anything like the freedom of speaking when there's nothing distracting or bothering you. The ESM-1-35H is so light and slim that you might not know you're wearing it. Securely attached with a single earclip, you'll never have to worry about mic placement.
Low Profile
The low-profile microphone is easy to use for on-camera or live presentations. It won't obstruct or cast an unwanted shadow when shooting video and is barely noticeable by the audience.
Single-Sided Earclip
For stability, the ESM-1-MN's single earclip adjusts to your ear and securely holds the microphone in place for applications from gym spin classes to large speaking venues.
