i know it may be stupid question but anyway:
this as small headphone amp with 2n2222?(picture attached)

There's so much wrong with this circuit as a headphone amp.

With so many circuits available, why build this? It's low impedance input and not very linear. I don't think it could even drive an iteration of itsself. You'd be way better off paralleling a couple of 5532s.

This is the kind of circuit you'd build in a beginning electronics class. It really doesn't have any practical use at all.
