The good news: It can be done.
The bad news: It will become costly and impractical.
You can tap the headphone signal, amplify it by an opamp and feed it into an
bar display driver like a LM3914, LM3915 or even an old uaa180. So far so
good but... You will need some design skills to make such a thing and when
you're ready you will find the circuit energy consuming like most LED
circuits do.
