Compliment headphones for DT 990 Pro?

Sup guys! I bought a pair of Beyerdynamic DT 990 Pros a few weeks ago and I absolutely love them! Properly amped up, the bass is ridiculous and often makes me feel as if I have two subwoofers attached to my head or I'm sitting in the middle of an IMAX theater (this is a good thing because it isn't muddy at all!). The soundstage is fantastic and I almost feel like I'm cheating when I play FPS games. 

Couldn't be any happier! 

But I'm not looking for some headphones to compliment them. I'd like something with preferably less treble, more forward mids and possibly less airy (smooth?). So in other words, I'm pretty much looking for the polar opposite of the DT 990, at least in-relation to the aforementioned qualities (I don't mind if the headphones are open, but I would love some better isolation). HOWEVER, these headphones NEED some decent bass because pretty much everything I listen to largely incorporates bass into the listening experience. 

My budget is $250. 

I've already thought about:

AKG K701/702: I heard they also have rather sharp treble and are severely lacking bass. Again, I've also heard that they sound rather metallic and sound very airy. However, they are very neutral, which is probably one of the last things that the DT 990 is. 

DT 880: I've thought a lot about these, but I'm worried about the mids; I've heard that they are also slightly recessed (albeit less than the DT 990s). More importantly, and from what I've gathered, they are "Un-EQ'd" DT 990s and are basically more neutral and thus retain the same sound signature (more or less). I would also like the novelty of owning headphones from a different company.

You are not going to like any of the AKG's if you're looking for bass in your tracks. Some like them, but knowing you like the DT990's bass, you're going to just not like the AKG approach to bass. You're a basshead.

 

Very best,

I don't know about those Ultrasone's. They seem to be a pair of bass monsters (just like my DT 990s) with recessed mids (JUST like my Dt 990s), so I honestly don't think that it would be worth getting them. 

How are the Grado Sr225i's? I've heard they've got really aggressive mids and are relatively "clear", with just enough bass so that I wouldn't feel underwhelmed listening to electronic music.

How are the mids on the HFI-680? I've heard a person or two say that the bass overpowered the mids.

Forget what I said earlier about bass. What I really meant was that the headphones need to have just enough bass so that it isn't detrimental to the overall experience. Ya know? Just enough to give violins and cellos some body and oomph and so that electronic music doesn't sound pathetic. 

Thanks for all the help guys! I'm currently looking at the HD 600s but I'm very worried about the "Sennheiser veil". The only amp I have is a Cmoy and a Little Dot Mk II and that isn't going to change for the next year or so.

Yeah...I don't want more of the same or even more of the same but "better". I want something that's "different". What's the cheapest you've seen the HD 650s or HD 600s on Amazon? It looks like it is definitely down to those two cans unless someone can point out something else. 

Because the prices have been fluctuating a lot. I saw DT 880s @ $210 on Amazon sometime in December and now the cheapest I can find them are $300.
