I don't know if maybe you don't use Bluetooth headphones, but no they don't have a physical cable you plug in. They do it wirelessly and with pad contacts.

Maybe they were saying the case needs a charging cable unless you do wireless charging?

And what are those pad contacts in? A charging case. Which needs to be charged via physical cable.
