u/Double-Percentage-15

I haven't been able to understand and googling only confuses me more.
Whats the difference between the two apart from no. Of attachments and bluetooth.
If they are the same thing, then could i get origin and later buy attachments. I have the option of receiving the origin case as a complimentary gift as well. However, I do want the whole premium feel of the box...is it worth it?

Also do I need the airwrap? Please see hair image and advice.
