My girlfriend and I both love using these at the gym. I packaged and shipped them back at half the purchase price. <1 month of occasional wear and the glitter is peeling off all over the place! The audio made hearing sounds fun again. But for the price, Id purchase these comfortable dress sandals over and over. First of I taught it could be from my carrier ,and I brought the issues to they intension they check everything in they hand which was all fine ,and they told me that it is phone it self ,after that I call the Samsung customer service for the same problem they also told usually they phone does not do such think like that but anyway they reset my phone to the manufacture setting to solve the issues yet nothing change still havin the same issues . I think the shoes could be improved if the sides were covered with the same material as the straps in order to create a more seamless-looking product. One doesnt even seem to have ANY wire in them AT ALL and will NOT bend and keep shape. The Velcro is sewn onto the foam strap. And some beaches have sharp rocks that I would want to explore around and while some other people had to hang back I could climb around and not worry.
