I have a few mono ear pieces from when I was in the military. I want to try and wire them up to the cable from some waterproof headphones for my EquiNox 900. Looking for a cable with the male screw on conector (maybe from a old waterproof headphones someone has laying around?) If you think you may have an old set and don't want them, I sure could use the cable. Pls let me know.
