MIRA Safety gas masks come with enhanced speech diaphragms that allow for improved communication over shorter distances. But talking through a gas mask is never easy. Especially if you’re not right next to each other or you’re dealing with any noise, weather, or other distractions.
The MIRA Safety Gas Mask Microphone is cross-compatible with all adult-sized MIRA Safety gas masks, making it easy to swap between masks for different types of missions.
Installation takes just a few seconds, and you’re ready to connect to your existing communication system. Just like a standard headset, the microphone requires no additional power, and it has an average life expectancy of 30,000 hours.
Gas mask microphones are a relatively minor upgrade that can make a massive difference while using your mask. Communicating via hand signals is difficult in the best situation, and it’s impossible if you’re holding a rifle or riot shield. Having the ability to plug into your existing comms helps you stay better informed and make better decisions when they matter most.

QUESTIONS & ANSWERS
The product description states that the microphone body is made out of "heavy-duty polymer construction." Can you tell me the exact plastic that you guys are using?
The Microphone's body is made of polyamide, and the exhalation cap is made of a mixture of polyphenylene oxide and styrene (the mic is embedded into a standard exhalation cap, similar to what you'd find on a stock mask).
