Guys , what's the real purpose of f the WM08 module, a couple of thing's , the plastic plug over the jack, it not water proof correct, 2nd thing i notice is , it doesn't have the 1/4 inch jack like the CTX3030 to plug most headphones in, 3rd , looks like the waterproof Equinox 800 headphones will plug into the module , used the 800 at the beach with wireless headphones worked great, ?s are when am i going to use it, the uses, purposes , as i can't find to much info on the module, i see the same connection on the head with the plastic cap, were the waterproof headphones would go, 1/4 inch jack headphone's are not usable , any info on this would be great, i would also add that they did include a wire if you don't want to use blue tooth , that would probably hook up, thanks Earl
