- Voice and audio comes through clear. It?s a quality cable. She paid back in trade very, very good. I heart my shoes. However, I am disappointed in the sound quality. The pediped flex shoes size 24 is tight fitting so bought pediped size 25/US 8-8. It?s awesome ??. Do not buy these expecting the best sound in the world. Even better you get an EXTRA paracord cable. for me that is great for all day errands and the like, I ordered a 9 1/2 for long walks and gym high intensity workouts .
