The thing is that the human ear has a similar response dip after 5kHz so that peak is not as pronounced in final perception as the graph would suggest.Ah the mighty Mt Treble aka bringer of pain.

I would say this is a myth. FR differs somewhat. DT880 BE (250 Ohm) with grey pads vs DT880-600
Same rig, same enclosure, same pads so easy to compare.
I agree that the small differences are probably not audible, though above 1kHz the 600 ohm version still appear lower in distortion but at levels I doubt matter. I also wonder if the 600 ohm version is less durable.Distortion in low frequencies fortunately are not very audible to us mortal beings.
When you EQ down 50Hz to 1kHz and the treble peak you won't even have to push up any frequencies more than a couple of dB at the very lowest frequencies.
I believe most of this is marketing talk. I have compared the 600 Ohm and 250 Ohm (same pads) side by side and one is not 'better' than the other, more detailed/refined or better in the lows to me.
The 600 Ohm versions are just less sensitive. More suited for OTL tube amps. Haven't heard 32 Ohm versions though.
Both are quite good headphones, certainly at this price. Impedance differences are not that big. The 32 Ohm is about 1/10th of the 250 Ohm where the 250 is only about 1/2 that of the 600 Ohm.
Measurements of various DT770's seem to show substantial tonal differences. It would be hard to defend these would only be caused by a slightly different weight of the voicecoil. I suspect there are more differences than that. Pads, internal damping schemes, clamping force, maybe even different formers or small differences in membrane.
Note that my distortion measurements can only be used to detect substantial deviations. But yes there are small differences there. Probably not audible as there are no weird peaks seen.
Power rating of the 32, 250 and 600 Ohm appear to be the same. One could conclude that the 600 Ohm version is not more sensitive to abuse. The slightly thinner wire might be more fragile when large excursions are made. You need quite a bit of voltage to do that with a 600 Ohm driver.
There is a substantial difference between an older and newer DT880 (same imp) and between an old DT990/600 and the current DT990/250.
These differences are unlikely to come from the voicecoil impedance only. The drivers seem to have (silently) changed over the years.
I assume since it has a metal headband it could be manually bent and or stretched by fitting them on something a little wider then my head to get them to my preferred clamping force?It does have a higher clamping force than the edition version.
I did bend the steel head bow both on my old DT880 and DT990 long ago to loosen the grip, it's easily done just by grabbing the middle of it with both hands and applying a little force.I assume since it has a metal headband it could be manually bent and or stretched by fitting them on something a little wider then my head to get them to my preferred clamping force?
