Hmm, IDK about you guys' hearing, but PSP on max volume is pretty damn loud for me (using stock PSP in-ear headphones).  I wouldn't go any louder lest I risk ear damage.  Probably only issue I have is with classical music - it's usually too quiet, but the dynamic normaliser usually does the job (if not, I can just edit the track to make it louder)

I know it might be difficult to hear some stuff on a loud bus, but I still wouldn't risk ear damage.  But that's your choice I guess >_>


Regardless, if you haven't tried it, try the Dynamic Normaliser (in sound settings).
I can't test sound quality though, but the PSP doesn't seem to have bad sound quality.
