However the seller is very easy to contact and offered a replacement parts. Wasnt my first choice for a slipper but read reviews on others and this seemed to have the best arch. I have a pair of devotion sneakers that are amazing. But if you made them sturdier, people would complain they’re too stiff. For audiophiles, the quality itself is about what you’d expect for something that doesn’t go in your ear, also the volume does not go that high and there’s no noise cancelling (but this isn’t a criticism, they’re supposed to do the direct opposite of cancelling outside noises)By far the best thing about them is the comfort/ease of use. La cancelación de ruido se activa en automático al momento de encenderlos y efectivamente "apaga" el ruido ambiental incluso por debajo de la mitad de su potencia. The latter side was, logically, a sharp decline. Surprise! The shoes are very confortable I order a 9 because I have a wide foot and they fit perfect if you have more a skinny foot I ouls maybe size down. But lets talk about putting the thing together because you have to do that out of the box.
