This 250ohm version of the DT770 is essentially a worse-sounding, harder to drive brother to the 80ohm version. The midrange is more veiled by the bass, which is a bit more boomy, and the highs are harsher. They are still very good cans, and of course built like a tank, but not worth buying when you could get the better-sounding, easier to drive 80ohm version at the same price, or even less. Perhaps their only potential benefit is the coiled cord, which can make them more convenient for portable, studio, or office use.
