Question DT 990 pro 250 OHM

Yep, looks like it. It doesn't list exact specs but it has impedance sensing and mentions driving up to 600ohms. And it has op-amps. I have 1990 Pros that are also 250ohm and they're fairly easy to drive. They're different drivers but the 990s are also on the easy to drive side of being 250ohm.
