The ear hooks just guide the cable over the ears, they don't support any weight, they're also referred to as cable guides. I just insert the IEM and bend the wire back over my ears with no particular care and then leave it alone, I don't try to make it match the shape of my ears as there is no reason to, it takes me no longer to fit them than an IEM with the pre-formed ear hooks. I imagine that wearing glasses with them will take a little longer to get them comfortable.
