The audio came through so clear that I had to turn it down a bit and the noise from the treadmill was totally minimized. Crocs Jibbitz 5 pack is a great choice. I’ve had these about a month now and I still like them. 10 size were on a smaller side. Cute shoe and fits as expected I would not recommend the Micd ones for working out as a little sweat can activate the button causing pauses and skips etc. I wear a size 7 always, always; these RUN A FULL SIZE TOO LARGE. In the paper instructions that come with the product, it doesnt mention the tools needed to tighten the bolts. ADORE these shoes for our little girl! This cable worked like a charm, back in action.
