IMPRES RSM SMALL 3.5 JACK EMERG
This IMPRES Windporting small remote speaker microphone with an IP55 water rating conveniently clips to your shirt pocket or lapel and enables easy communication without having to remove the radio from your belt. Motorola's exclusive IMPRES technology improves voice intelligibility and amplifies loudness--even in noisy situations.

This windporting microphone is also designed to prevent water from clogging the microphone port and distorting your transmit audio.
