The PMMN4066A Remote Speaker Microphone (RSM) is an essential heavy-duty accessory designed for professional use with Motorola Mototrbo R7 and R7a two-way radios. It enables instant communication via a rugged Push-To-Talk button, allowing users to stay connected seamlessly without having to constantly remove the radio from their tactical vest, pocket, or belt holster.

This model guarantees crystal-clear audio and high speaker output, ensuring you can hear and be heard perfectly even in extreme environments—such as high-noise construction sites, manufacturing plants, or tactical operations.

Durability & Ergonomics

Constructed from high-impact ABS plastic, the housing is engineered to withstand drops and severe operational wear. The reinforced coiled cable offers superior resistance to kinking, overstretching, and sub-zero temperatures. Thanks to its ergonomic design, the microphone fits comfortably in your hand, even when operating with thick heavy-duty gloves.
