So my DT990 (as well as my K701, though I'm doing these just for the heck of it, as they already had over 200 hours, not including previous owner) have been burning in pretty much 24-7 for the past week and a half (20 minute pink noise, 2 minute silence on endless loop). I dunno what it translates to time-wise, but I assume over 100 hours so far. Once my E9 comes in, I'll be burning the amp WITH my DT990s and K701 as well.

I haven't really tested the DT990s much since the first few days though, I'm just trying to get them all ready for Black Ops.

Honestly I do love these PC360's but I'm just not sure they're going to work out for me comfort wise - they even look small...I just don't get it! I hate getting stuff though the mail and having to deal with sending it back, paying for shipping (again), and having money tied up.
Oh...and on that same note...with the DT770's what did your mic rig look like?
For all my headphones after my A40s died, I didn't use a mic (with the exception of the Creative Aurvana Live, Turtle Beach Z2, and PX21).
So even notoriously hard to drive headphones like the K701 was powered quite well when setting the game/voice knob to be dialed fully towards the game side, meaning no voice chat. The DT770 Pros were no different. They are definitely a LOT easier to drive than my 600ohm DT990s and K701, though I think if you plan on attaching a mic to the DT770 Pros, they will need some amping, because leaning towards voice underpowers them significantly.
I personally wouldn't recommend the DT770 Pros for multiplayer gaming as they are too bass heavy for competitive gaming. You'll want something a little lighter on the bass. I think the bassiest headphones I have tried that work well with multiplayer gaming is the Creative Aurvana Live and DT990. Even then I'd go lighter on the bass than both of these for multi, which is why I have the K701. Again, if the DT880's had better positional cues (and this is debatable, YMMV for sure), they'd be one of the best headphones to use for gaming, whether single or multiplayer. They did practically everything right for me.
If I had to take an educated guess by what I've read on the forums, the Premium DT770s are a LOOOOT more balanced than the Pros, and would work quite well for gaming, which is why I guess the MMX300 was made (essentially a DT770 32ohm with a mic, though they may be mored tuned in favor for gaming purposes).
I was debating on getting the DT770 32 or 600ohm but then I figured I'd get the 990s as I no longer needed a closed headphone. Since my E9 is on it's way I would have definitely went with a 770/600ohm if I needed a closed headphone. I hear they're one of the very best closed headphones out there.
I believe that if the E9 does as well as I hope, I plan on getting a Califone mic to use in conjuction with both my K701 and DT990s.
