The 250 Ohm and 32 Ohm version are balanced with very similar sound signatures. They’re meant to match your gear and your use case. The short cable and leatherette pads of the 32 ohm version are better for mobile use, and the 250ohm version pairs better with desktop/studio hardware.
But they sound nigh-identical. I can’t really make the decision for you and your ears! If you’ve already heard a DT770 you know what to expect. None of them are dramatically different from each other. The 80 ohm version has slightly more bass due to the construction differences mentioned in Zombie’s guide.
