The cable is definitely a weakness. I've noticed that along with wanting to straighten out, the individual cables to the earphones do not like to twist at all. It wouldn't be a problem except that one of the ears wasn't assembled at the same (reciprocal) angle to the other, so when wearing the phones, one side has a slight torque, which is probably what pops the cable over my ear if I allow too much slack around the ear.
I find that the chin slider solves the problem though.
Really, it's a minor issue with an otherwise fantastic headphone. Hardly a deal breaker, IMHO.
Congratulations on reading my mind better than I could.
