Oh yeah, don't get the PX100. I personally have recommended the PX100s for music, but they really won't gel too well with movies and such. That's because they have a predominantly "sweet" sound, which is pretty much the opposite of what you need for movies and what not, but exactly the kind of sound you need for a lot of genres of music.
If I'm not wrong you mean PX100 is lacking the bass, right? So, I guess HD202 will be better option for movie??
