I know that this is late but there is a bigger solution to fixing this.
I just tried this product yesterday on my skullcandy wireless crushers, now i have pictures that it definitely holds, sturdy as heck and unlike other glues a little does go a long way.
The glue i used is loctite epoxy plastic bonder. And also you can cover any of it with black paint as well. (20 minutes to bond, 24 hours to completely cure.
