I'm hoping some of my fellow hams in here are pilots who would recognize this helmet and let me know some specs on it. I've tried it on and it does a fantastic job of blocking outside noise interference. I was thinking it'd be cool to wear in the shack sometime. I could just close my eyes and imagine I'm flying! The questions I would have though are what kind of connector is this on the end? It's kind of like a 1/4" stereo connector but shorter and TRRS. Also what impedance for the earpieces and mic? So I'm picturing building a converter box with a socket to plug it in to, and then some kind of matching to the proper impedance for mic and headphones to my rig. I'm also thinking the lightning bolts will help with DX!
