What is IP57? 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 capacity 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.
