How do you get soft curls?

I wonder what that's like, soft curls. It seems every product I have or tried gives me crunchy curls (crunchiness varies with product).

Normally I use a leave-in under my product(s). I apply to very wet hair. For a while I've used only gels, but I've since ventured out to creams and mousse. But I get crunchy curls from everything.

So how do you get soft curls? Tips, tricks, techniques, product recs?

btw, going productless is not an option for me.
