Hmm, thanks for clarifying. I know it was mentioned that they sounded great with games (I wasn't really saying anyone said otherwise, I was simply focusing on the "movie" aspect is all--my bad for not being specific), but I was looking for a games + movies headset, with movies being the most important. Not because I watch movies much more than I game, but because I think it's easier to enjoy [non FPS] games with any "decent" headphones than it is to have a truly awesome experience watching movies.
What is your source for DH anyway, a dedicated receiver, or are you using one of the smaller DACs? Are you using any EQ? I only ask, because I'm going to have to end up buying not only a headphone amp, but possibly an EQ. Price wise, they don't seem to be that much more than the DT990's, but the main issue is still finding a good place to purchase them from new.
I did read the product description, and saw nothing mentioned about Dolby Headphone anywhere for the 900 series--which is why I started questioning compatibility in the first place. However, I do see it listed for the "HFI-780's" which they claim were tailored specifically for gaming and movie watching.
Edit: Bleh, impulse buying FTW? I'll have my 900s next week. Hopefully I won't need to modify the bass back at all. Since these are not for critical music listening (even though they are still supposed to sound great even with non DNB/Hip-Hop) it should not matter too much. Plus, I want that subwoofer feeling for movies and games anyway. Just in time for the LOTR and Star Wars (original) Blu-Ray trilogies eh?
