The SPM-8X is a comfortable throat microphone/D-earset combination for communication in high-noise environments and in other extreme conditions.
The throat microphone, softly secured by a flexible and washable neck band is sensitive and needs only light pressure on the throat which makes it comfortable to wear. The throat microphone is even sensitive to whispering. The effective earset that hooks on the ear ensures clear reception even in areas of high ambient noise levels.
The SPM-8X requires an RSM or PTT unit to connect it to the THR9 Ex radio.
