It's that easy. I would have assumed people would be able to figure out something so obvious, but I always read complaints about the wing system. I'm sure you could make it prettier if you wanted to.
After this "mod" they are one of the most comfortable headphones I've ever worn. They don't focus all the weight on the very top of your head like many headphones do.
Plus they sound great. I prefer them over HD650s, DT770s, XB1000s, D600s, and many more. Close to perfect in my opinion.
