Design
The DT 990s win the design competition, with their superior aesthetics and metal. The HD 555s are plasticky and don't inspire much confidence in their durability.
Sound Quality
The DT 990s had a better frequency response. Though both headphones had questionable high ends, the HD 555s' response suffers a much more dire fate than the DT 990s'.
The HD 555s have quite a bit of distortion towards their low end. The DT 990s, on the other hand, don't.
The DT 990s have a better tracking result. Both headphones have problems in the frequency range, but the HD 555s' were much worse.
Isolation
Neither one of these things has good isolation.
Comfort
The HD 555s are much more lightweight and feature more padding. They're far more comfortable overall.

Verdict
This is a budget and comfort match-up. On a budget? The HD 555s are a far, far better option for you. Think the DT 990s are super duper uncomfortable? The HD 555s will probably be more comfortable. If you're looking for great audio quality, however, with reckless disregard for the wellbeing of your skull, the DT 990s are probably the better choice.
