I've had the D2000 for a little over a week now. For dynamic headphones I don't think they're that bad, it sure is hard to listen to them after electrostats though
They beat the DT880 and DT990 by a mile which I couldn't stand. And are better than the HD580 at low listening levels, which I find need to be cranked up to sound good. The Senns have a more even FR when turned up.
That's my 2c.
