Do you have an Amp? If so, I'd go with the 4xx. Otherwise, go with the 32ohm DT990.
I own the 4xx and the DT990 600ohm and prefer the 4xx. I have had no durability issues with the 4xx. This was not the case with the 400i I had before the 4xx. The DT990 are lighter and very comfortable, but to my ear when properly amped the 4xx are hard to beat.
