I am big fan of Shure products and working as a sound engineer I have acquired quite a bit of gear over the years. Recently I had found out about new replaceable cables that had in-line microphones and now I hear that they have have a replaceable blue-tooth unit as well. I was wondering if anyone has tried them on and if they have how much do you think it degrades the sound. I really like to go running and I have a pair of bose soundsport wireless but if I could maybe run with a shure IEM hooked up to the bluetooth unit I would like to give it a try. Tell me what you think!
