Im really disappointed, and cant return them. If you?re planning on purchasing online, you may consider going half a size up as well. I bought this silicone case a few months ago and have been pretty happy with it until yesterday when it ripped right where it folds to close the case. The sound quality is decent. Lo he usado alrededor de 3 horas y sin problemas, son muy ligeros y sus almohadillas cubren toda la oreja, por lo que no incomodan. Pretty happy with that. I got the smallest size in the crocs 4/5 assuming they would be a litle bigger and they fit him perfect. My fault for not reading the reviews and seeing what other people are saying about thi cable. I will say that most of the ladies I work with were shocked at how flexible these shoes are and it feels like you?re walk-in on a sturdy cloud! The build quality for a portable is very good, in my opinion.
