The USB cap I found again, the other is probably lost.
It may be that it fits with other mobile phones and works well but unfortunately not in this.
The connector from the headset falls off to the rear, think that here the problem is that it is easier to get out.
As mentioned in a comment I have sometimes tried the USB cap wrong einzusetzten rum: Does not work when Xperia SP. Shame
My review refers only to the Sony Xperia SP! I do not want to denigrate because it determines super harmonized with other phones of this product. It should rather be the owner a notice of Xperia SP.
