Hi, I have a choice of getting one of these headphones and am not sure of which one would fit my liking more. I'm not a huge fan of bass I'm more of a, "Midhead." I am aware the 990 is open air which is fine with me. 
 
(Both are 250 ohms.)

The mids aren't amazing on the 770s without increasing volume and are kind of dominated by the bass/highs. Not sure what the 990s are like, but I dunno if I'd go with bassy headphones if your into mids.

My preference would be the DT990. The DT770 is a good headphone but after a while, that dominant bass can become a little jarring. The DT990 also has quite a bass kick but not as much as the 779.
 
The DT990 has a 'u' shaped FR curve. I guess that you have to choose one or the other?
 
One headphone that I find more balanced is the AKG K601 and if it's still available, can be had for a really good price.
