PMMN4027A: Remote Speaker Mic with the IP57 rating. The IP57 is a higher rating than the standard IP54 that helps provide first responders with high reliability in emergency situations. The number "5" stands for the dust intrusion rating, or the capcaity to withstand the effects of fine, abrasive dust particles. The "7" means a higher water intrusion rating. The head of the microphone has been tested for 30 minutes of submersion at 1 meter, but the connector is not similarly rated. This new remote speaker mic has the new Windporting feature that dramtically lessens background noise from high winds and other severe weather conditions. Audio can also pass through the speaker grill when blocked by water. This Microphone does NOT have a seperate audio jack located on the micophone.
