Very sturdy and for my purpose was the best choice. It just sits in my closet. Very quality moc, would recommend. ¿Por menos de $3000 pesos? Si hay alguien que se queja y diga que es lento, que sus cámaras son malas, que no es lo que esperaban, o cosas asi, les aseguro que mienten. They are very comfy, though. I took a star off because they are hard to get on at first. Good detailed instruments sounds. Having said that, we were recently at a function and a friend was wearing these shoes. The battery life is surprisingly healthy. For the price it?s a great portable speaker.
