Windporting Remote Speaker Microphone, IP57

The Motorola PMMN4029A Windporting Remote Speaker Microphone is a rugged audio accessory designed to provide convenient push-to-talk communication and clear received audio for compatible Motorola portable two-way radios.

Featuring Motorola Windporting technology, the PMMN4029A is engineered to reduce the effects of wind noise during outdoor communications. Windporting helps minimize the whining and howling sounds that can occur when wind passes across the microphone while also helping prevent water from obstructing the microphone opening, resulting in clearer voice transmissions in challenging weather conditions.

The PMMN4029A features an IP57-rated housing designed for demanding professional environments. The microphone can withstand immersion in up to 1 meter of water for approximately 30 minutes and provides protection against dust that could interfere with normal operation.

An integrated push-to-talk (PTT) button allows users to transmit without removing the radio from their belt or carrying case, while the built-in speaker places incoming radio traffic closer to the user for convenient monitoring. The coiled cable provides freedom of movement, and the swivel clothing clip allows the microphone to be positioned conveniently on a shirt, jacket, vest, or other workwear.

Ideal for construction, transportation, utilities, maintenance, security, manufacturing, public works, hospitality, and outdoor operations, the PMMN4029A provides a durable remote audio solution for professionals working in demanding environments.
