The contents of the box seems to differ between regions, for example, in Sweden and France the DK31 magnetic charger is included in the packaging, and also included in French boxes (and not the Swedish ones) is the MH750 wired headset. Just google "xperia z1 site:shop.sonymobile.com" and look at the contents in different regions.
For example, in boxes destined for the UK the contents are:
- EP880 Charger
- EC801 Media Cable
- MH750 Wired headset
- ET970 Screen Protector
...presumably there is also an Xperia Z1 in there as well.
