Yes, you were right about them. They are seriously good with Dolby Headphone. And that bolded text is spot on.
These are probably the best headphones for gaming I've personally heard (although I've heard the T1 and HD800, I haven't heard them for gaming). I say this because they have the highest combination of "competitive" and "fun" I've heard in one headphone. I haven't heard the D7000s, but I bet they have a lot of both categories as well. The X1s have have a fun home-theatery sounding signature with a mild "U" shape, with more emphasis on the left side of the "U" then the right side. I was expecting them to have a signature like this, but I wasn't expecting them to pull of this kind of soundstage while doing it.
Their soundstage and imaging are both excellent. The soundstage comes across as being even larger and more roomy and open sounding then the Anniversaries. It's on par with the Q701 in that regard, but the Q701 is thinner sounding and sounds primarily mid-rangey in a direct comparison (a la HD598). The X1s keeps the same size soundstage as the Q701 but are punchier with impressively visceral bass topping everything off.
The X1's secret to pulling all this off is in by having smaller sounding instruments with plenty of room around each other. The T1 does this also. The Anniversaries instruments sound larger, and as a result become more crowded and intimate sounding inside the soundstage. As the size of the instruments increases, it becomes more of a struggle for the headphone to keep an impression of soundstage size and space. These large intimate sounding instruments can be cool, and are nice for some music, but for gaming the X1s really benefit from having the type of presentation they do.
For music these are also excellent, but not necessarily a replacement for the Anniversary. This is because they have different signatures so personal preferences will come into play. The AKGs focus more attention on the mids, while the X1s spread the signature around a bit more with the bass receiving some TLC. I'll go more into the sound sigs later, but I will say that I really enjoy the X1s signature and it's a nice compliment to the AKGs.
My new goal is to get MLE to buy a pair of these ASAP, as I think they are the perfect headphone for him. MLE, I will take pictures of the headband for you (next to the AKGs as well) so you can see what you will have to work with as far as bending them. I know you can make them fit your fat head if you try!!
