A very bad and inferior product. The bag does not fit correctly, it looks as if one has just lazy the size and position of the recess adapted as a model a bit to make order checkout. For a pair of headphones can be connected namely because the closure is in the way, which quite clearly shows that the bag is not suitable for the Xperia SP and was not designed for this. Worse, however, is that the housing does not fit properly on the On / Off button. The plastic is permanently under pressure because the borders of the button from the bottom pushes against it. This has ultimately led to the plastic is broken after only one month.
