DT990-250 Frequency Response and CSD Waterfall Plots

As many of us have suspected, no QC issues with the "classic" line.


As usual, note CSDs start from 500Hz. Floor set to -36db. These confirm subjective impressions of flat midrange and good behavior - not too much ringing. Just a lot of treble. Best to EQ it down since EQ will actually work on this headphone.

Would higher output impedance help?

If the impedance graph has anywhere near the same shape as the 600ohm version, probably not. Maybe more mid-bass and a very slight increase in the last octave.

I do have the 600ohm version I can send in if people are interested in seeing if they measure differently at all. I don't really listen to it too much anymore. A little congested overall, and bass is slightly loose to me.

i really enjoyed my time with the dt990/600.  i agree, it's a bit spot-lit in the treble and a bit warm in the bass, but nails the dynamics pretty well.  the tone was a bit too dry for my tastes over time.

I fail to see how the T1 is better than this headphone though. This headphone is EQ'able. The T1 not so much so.

It's better because it's more expensive  :P

I haven't listened to my 990's in ages to really compare... but going on memory the two areas the T1 edges it out is in detail retrieval and sound stage.

Not that this would make them better headphones...

Yeah, well, you know, that's just, like, your opinion, man.

The DT990 beats the T1 in bass and comfort (clamping/earpads). And fun.

Today I was supposed to meet a very "motivated" buyer in Anaheim Hills. Waited for the dude for 45 min, called him twice (didn't pick up), and in the end gave up on him... I'm so keeping my DT990s! I'll call it the fun-phone, or maybe my reminder.

Heh, that's my neck of the woods. Thinking about selling my DT990s as well.
