No. He only likes his dt990 with worn pads.

Well.
Anyway, I think the measurements imply that unlike the old Beyerdynamic 1990 the more "analytical" mixing pads might be the true star here. This would be at least the reason why I'd try them out.

Even if the many messages in this thread already imply that a lot of non-pro listeners use this headphones as an all-day driver, I want to emphasize as a non-pro user: I decided very carefully many years ago to buy this headphones and I still like and like to use as first choice open headphone. I think we don't want that any non-pro user feels a bit insecure when deciding pro or contra buying this thing just because of himself being a non-pro.

Where can I find a replacement headband for the 1990s? They are crumbling and seems to not be in stock anywhere.
Few years ago I ordered one from Amazon, but it doesn't seem available anymore.

I don't like to be pedantic, but...
You've got this part backwards. The original has efficiency of 102dB/1mW, the Mk II is 94dB/1mW. If I recall, their sensitivity is only about 1dB difference at 1V.
The new ones require significantly more power, but only slightly less voltage than the old ones.

Eh, sorry if I come across as a know-it-all. I tried to spout off my response between my kid bossing me around (geez, kid, can't you see I'm busy talking to strangers online?!) and my dog complaining that she needs to go out NOW (again, busy!), and, well, I probably end up seeming more like an asshat than I want. Not that I'm not an asshat. I just don't want to seem like an asshat. I try to make up for it with cute gifs.
But seriously, sorry if your blood pressure went up when you saw my post. I really didn't mean it.
Yes, when impedance goes up, then required current goes down and voltage goes up, assuming that the required power (efficiency) stays the same. But if the efficiency changes, then it's not as simple.
Power needed for a given SPL can be calculated like this:
Pt = 10t-e/10
Pt = power required to reach target SPL "t", t = target SPL (dB), e = headphone efficiency (dB/mW)
For the Mk2 to reach 100dBSPL: PMk2 100dB = 10100-94/10 ≈ 3.98mW
For the Mk1 to reach 100dBSPL: PMk1 100dB = 10100-102/10 ≈ 0.63mW
Using this calculator, the sensitivity of the Mk2 is 109.2dB/1V, and the Mk1 is 108dB/1V.
You can either use a similar equation to the one above for 100dB: Vt = 10t-s/20, where s = sensitivity (dB/1V)
VMk2 100dB = 10100-109.2/20 ≈ 0.35V
VMk1 100dB = 10100-108/20 ≈ 0.4V
Or use Ohm's law (Hi, Georg!):
P = VI, I = V/Z, so P = V2/Z, V = √(PZ)
VMk2 100dB = √(0.00398*30) ≈ 0.35V
VMk1 100dB = √(0.00063*250) ≈ 0.4V
Mk2 needs 6.3x as much power as Mk1.
Mk2 needs 7/8 as much voltage as Mk1.
Despite the low impedance of the new drivers, but because of their lower efficiency, they require nearly the same amount of voltage as the older higher Z drivers.
It's made even more confusing that Beyer's own copy says that the new headphones are for devices that can't provide enough voltage the old ones. "If only my phone had 1/8 more voltage! I could listen 1.2 decibels louder!! Grrr!!!"
I'll stop now before I find another stupid typo I have to fix. And hopefully before you've become completely apoplectic.

I see that solderdude has already uploaded his extensive review/measurements:
https://diyaudioheaven.wordpress.com/headphones/measurements/brands-a-i/dt-1990-pro-mkii/
It seems that not all improvements desired by audiophiles have been made. The hot treble is still there, but then it's made for analytical studio use.

I like the design of the old ones better. The texturing of the earcups on the MkII doesn't fit my taste. Same goes for the bulged part with the DT 1990 Pro lettering.
Anyways, what matters most is the sound of course and it seems like the highs have been tamed a bit. To me it seems like many people still need to EQ them tough for the sound to be really pleasing. So it doesn't matter if you buy the OG or MkII, both might need EQ to have satisfying sound. Therefore I'd end up preferring the OG because of the design and the more flexible hinge.

The overhype on this headphone from....a certain reviewer....was something I should have ignored. It was not a good headphone. Maybe it is fine for a $500 studio headphone. But it is not an audiophile headphone.

I am an audiophile. Since I rate the DT 1990 with Analytical pads above a Sennheiser HD800S and Audeze LCD-X, I strongly disagree with your opinion.

Have you tried the DT880 600 Ohm? That one I really liked.
