Great product and customer service. He isn?t a runner but he is on his feet most of the day and needs a shoe that is comfortable and well-made. Son muy cómodos de usar y los materiales son de buena calidad. Ive owned many mounts, some good and some not so good. These are nice to wear and they feel great on my feet. The navy is darker than the Rokkit FF navy, but they still work with blues. ? Buena carga rápida de 5 horas de uso en 15 minutos de carga. They are the most comfortable slippers I have ever owned. La parte interior de los cascos tiene una almohadilla gruesa que forma un hueco amplio que yo creo sirve para dos cosas. One very important issue for me with headphones is comfort.
