Any first responder that uses a shoulder microphone knows that finding a convenient way to wear it that places it in an ideal spot securely is not as easy as it should be. I tried many options over the years from using my wife's hair ties to threading a split ring through my uniform (which eventually tore my shirt) and everything in between. I've had, my microphone tear itself off my uniform during shift more times than I care to count. From struggling with suspects, to knocking it off with the butt of my shotgun or rifle, I knew there had to be an easier way to secure what is essentially your direct line to dispatch and backup.
One night several years ago this idea just popped into my head. A small device that I could just slip into my pen pocket with an arm that would hold the microphone clip centered on the chest. It would not require modifications to the uniform, but would be held securely in the pocket. After much time testing different different sizes and shapes out of G-10 (which is what I had on hand since I make knife handles out of it and it is fairly easy to work with) I had a finalized version 3D printed. I finalized the dimensions of the MAD, but the printed version was not strong enough (and was somewhat cost prohibitive). I then sought out a company in the US to have the MAD injection molded. Through trial and error, I found the nylon molded parts to be the both pliable and strong.
