Ok, I see what you have done.
The headphones need to be like this:
The original way.
Do not resize them, move them etc.
What you can do however is put the head underneath them so the headphones are on top of the hat.
So have the head like this:
except have the headphones the original size and placement I gave you, except on the outside of the head.
Also make the head match up at the back.
Is anyone else giving this set a go?
