Not to hijack this thread, but this morning I took some time to test spots on the armor to place the mics. I initially put them up in the chest plate, but they picked up waaaay too much of my vocal speaker. So I moved them down near my waist, and it seems to work great. I played some music from my phone to see how much I could turn up the volume and still hear my surroundings on top of my mic. I have a troop this weekend that I can really test it out on, but I think it will work great. Here's what I did. Obviously I'm going to need to clean up the cables and get the mics permanently installed with some sort of hooks or Velcro. I'm using a Bluetooth transmitter to earbuds that I'll wear under my balaclava. There is a slight delay, but I don't think it'll bother me. Worst case, if it does, I'll run some wired earbuds.
