MH-57
Robust, handy and with good speech intelligibility
The MH-57 series was originally developed as a cockpit microphone and is a classic that is popular not only in the aviation sector. It is a robust dynamic microphone that achieves high speech intelligibility by suppressing interference noise particularly well in the lower frequency range. The housing is made of durable, impact-resistant plastic. The push-to-talk button with a normally open contact is easy to operate even when wearing gloves.
