Genuine replacement. The microphone is packaged very well for transport or storage when not n use. Just for review, look at these feature photos that sold me on making the purchase. Im usually a 7 but bought the 6, as the listing said. She complains about most shoes not being comfortable but had nothing to say with these and they were easy to put on. I am a slipper person. I wear them cycling and kayaking for hours at time. *** Please note that we have only been using these for 1 week . I always wear socks with these kind of slippers, anyway, so if I wear much thicker socks, these slippers do work okay. The price cant be beat.
