While they have (IMHO) some serious flaws to call them a good or even worth considering headphone... at least for music, they might shine at professional FPS gaming.
Excessive treble and soundstage translates real well into hearing the positioning of the enemy.
I wouldn't say they are peculiar for movies... they have some bass, but the sucked out mids are a no-go for any decent movie (without excessive explosions), plus the treble...
I'd rater go for an equalized DT990 or an HD650 for movies... or an AKG K240s for cheapskates.
I would skip on the HD700 for music listening though.
