Great trainers for the money. Son de excelente calidad, el color es hermoso y casi no pesan. I had constant technical issues with them, the mic quality was terrible, a computer would recognize the mic but no sound would come from the mic. I bought all my parts from various places to save money as they are expensive. The wires are super cheap and didnt last long. These particular ones have a new memory type foam in them, but their similar to the previous generation bistro crocs, just the little dots on the inside foot bed are now big dots! Even so, a very cute shoe but I returned them because they were too small. Outside this speaker can be heard across a large outdoor area. I cant imaging anyone being disappointed. Quality feels much better than Ellie.
