Cut cables in headband
Skullcandy Crusher Wireless
"I presume you have a soldering iron. If not, go buy a cheap one. they are not very expensive and will pay for it self in repairs. I also suggest heat shrink, but electrical tape works too. Now yes, those wires are VERY tiny and delicate, but you can do it. Here is a vid on how to splice wires. and this goes for any wires.
Best of luck! And try not to pull out your hair when you break the cable in the process XD"
