Starting a new job tomorrow, so I am looking for a headphone refresh.  Currently, I have:
 
iPhone 4 -> Line out
cmoyBB 2.03 w/ AD8620ARZ
HD280 Pro
 
I listen to mostly iTunes Match music (256 AAC) and internet radio(higher quality AAC).  My music choices are pretty wide ranging:
 
Adele, Arctic Monkey's, Beatles, Black Keys, Cake, Gorillaz, Kanye, Jay-z, M83, Queen, Journey, Roots, plus lots of Rap/RB radio.
 
Requirements:
 
I need something closed as I will be working in an open office environment.  My biggest complaint about the HD280pros is the bland sound that comes out of them and they aren't very bassy.  I will be using these at my desk, and not on my commute, I have other headphones for that so size isn't important.  Just looking for something comfortable and good sounding, with good bass.
 
I would like to keep my budget less than 200.

The Ultrasone HFI-580 would do well for you. They would have the bass you need for your music types, good clarity too.

Would there be any point in going a little higher in price?

Well, I'm just stating what I think would work best for you. If you want something higher in price, the HD-25 II would be nice, though they're on ear.
