The cable connectors hasn't gotten loose or spoiled in any way for me, and I actually keep removing and putting other cables. Now I just got different adapters.
That said, if you wear the customs over the ears, there shouldn't be much strain on the connectors. The ears should actually feel more strain. As long as there is no hard pull on the cable while sleeping, which doesn't happen, you'll be fine.
@Benny: The customs don't need an amp to shine or for you to enjoy them, I use it with my NS & iPad unamped, and it works brilliantly. Obviously, they do benefit a lot from amplification & a DAC, but they're extremely enjoyable without. The versatility of the customs is another great positive.
