look at these closed/portable options: Sennheiser Momentum Over-Ear ($300 on sale), nad viso HP 50 ($300), AKG K545 ($200 on sale at razerdogaudio), and the Sony mdr-1r ($200-or-less). If you are a basshead, you can consider the V-moda M100 ($300ish) + $20 XL pads.
all of them should be comparable in sonic quality; mostly differ in sound signatures. All are I have not personally heard the mp50 or the k545, though I read on the k545 that some people though the k545 outperformed both the more expensive momentums & hp50. Note the Momentum Over-Ear has small earcups, so real life usage may be more on-ear.
edit: if its indoors use only, you can consider the AKG K550 ($220ish - closed) or the AKG Q701 ($220ish - open)... or Sennheiser HD 598 ($200ish - open). these headphones are rather bulky or are open so will leak sound out/in, so they are not suitable for commuting, but they would be fine for sitting at home listening.
I reread your post & saw you don't mind sound leakage, so I would go for the AKG Q701 vs Sennheiser HD598 vs Beyer DT990 32ohms. These are all open options. You will find better sound stage & generally better sound quality with open, while closed are good for portable use & can have more bass.
Note sound quality does not correlate with price above the $200 range.
