When ur watching a movie, press trinagle and u can put the volume up to 2+. Thats only when your watching a UMD movie though. I hate the sound as well, its so soft. Thats the only hing i know.

do you mean the official sony psp headphones?
i found this too, and as i know there is no way to get round this
and after reading the manual the official psp headphones have a volume limiter for safety's sake- e.g traffic, road safety and overall protection of your ears
You could also consider building an audio amp like the one Mofo posted in that thread or clink the link in my first post in that thread. Otherwise, use Google, don't worry it won't bite, or the search button at the top of the page.
