This thing rules. Obviously without coming right out and saying it. However, I have had these for a couple weeks and I noticed after a wear or two, the leather began pleating. Protection= 5/5The case is made out of a hard shell plastic material with a nylon outer material. They Fit to Tight, and I got a size 12 and My old Flip Flops where Size 11. Its crazy to me that the sizing cant be more consistent. So I have to shove my foot in. I liked the sizing and the number of shoes it store. For the price/value/ quality equation home listening phones, I have yet to find one that matches these headphones. Muy buena calidad, duracion de bateria hasta 5 horas de uso continuo, la calidad del audio es malo inclusive al encender/apagar el sonido de bienvenida la calidad es muy baja, usando alguna aplicación para modificar la calidad del audio mejora bastante, ademas me hubiera gustado que incluyeran un estuche ya que traerlos en la mochila se activan constantemente y cuando necesito usarlos la bateria esta gastada.
