Anders_ASUSthanks. 🙂 i just bouught an adapter. i forgot to update it.. 🙂
Solve it with some L-shaped adapter or USB-hub so you can both charge and connect your headphone to the side port at the same time.
I won't recommend any adapter but you can search for one yourself. Just remember that other phones don't have a sideport so this would have been an even bigger issue if you didn't have ROG Phone II
