Would they hold up well watching movies like Star Wars, Dark Knight, etc. or feel dull/off/very un-theater like? Side note: I'm not implying I'm looking for a movie headphone - I'm aware there's tons out there better for movies probably...I'm looking at the PM3 primarily for music but want to know how well they'll hold up for my viewing on the side.

Thanks!

Bass is a hard thing to compare as part of the "movie experience" is feeling the bass too, which is impossible to replicate in a headphone. You'd be better off buying a speaker set up if you want that sort of experience.

Whether you'll like the PM3 for music depends more on your preferred taste, You haven't particularly listed much information so I can't help you out there.
