Update:
Thank you everyone for your comments and opinions!

After cooling my head down a bit and using my APP2 and a pair of Beyer T90 that I still have, I concluded that I shouldn't get another set of over-ears at this time...I should have mentioned it, but since I wear glasses, using overheads during work is really uncomfortable, even with headphones as light as the T90. Anyhow, I'll hope to get a good near-field setup for work after moving to a new place in the new future :)
