Aunque tengo que dar un apuntes con esto, y es que a volumen máximo los dos auriculares se igualan, es a medio volumen donde se nota esta diferencia. There is more plastic to the shoes than I would have preferred but at this price point, if they last a year i will be thrilled. I really like the shoes except for those cushions which ruin them for me. The wiring is sufficient and weatherproofed with a rubber seal at the entry point into the enclosure. They’re super comfortable and keep my feet nice and warm without making them sweaty. I have three pairs and will continue to purchase them in the future. The charger you purchase with the iPhone 12, 12 Pro is much faster at 20W, but if you charging overnight it doesn’t matter. I love the workmanship on the shoe rack. that great! I find it totally comfortable.
