seems like, analogically, hd600 = er4sr and hd650 = er4xr
The current original pads differ a bit from the ones the HD600 (and 650,580,58x,660) came with originally.· The last few weeks I've been using the HD 600 with Oratory's equalization and new original pads.
I've always wondered why Sennheiser makes what, 3-4 headphones that are so close to the same that they might as well be one model. Strange marketing, though I suppose it has worked for them.Only on average though:

When comparing one HD600 to one HD650, unit variation can tip it to either side:

I've been using Oratory's equalization files for each model, which should make the difference between both models much lower, so I guess it could be just unit variation. Although I think Oratory should have made at least two different EQs depending on pad compression, but let's believe that both headphone models have almost the same amount of measurements with used pads and new pads (19 units of HD 600 and 21 of HD 650). Anyways, if it's just unit variation and luck, I'm quite happy in any case, since this pair definetly sounds more natural on vocals to my ears. Maybe I'm a bit paranoid but I wanted to sell my old HD 600 because I thought drivers could degradate a bit with age (it was 7 years old already) and I ended up enjoying more this pair of HD 650.When both the HD600 and HD650 have the same pads (not all HD650 are created equal) the HD650 will be a bit warmer/fuller and thus comparatively less 'clear/bright'.
Just bought a second hand HD580 Precision again. Assumed to be the 3rd iteration.
Finished the review just now.
Those that are looking for a nice 'cross' between HD600 and HD650 and don't care for nice paint jobs should look into the HD580 Jubilee.
Funny to see/hear that the HD600/650 aren't really any better than this 30 year old predecessor, just slightly different in the lows/warmth. It is actually right between these 2 models and being just a hair 'brighter'.

Not at all surprised. I've had a pair of 580s since the mid-late 1990s, so similar vintage as yours. For years they were my "good" headphones - in a rotation with Koss KSC-35 and Ety ER-4. They've been around the world. They beat the OG Orpheus (IMO) in an A-B comparison when driven off of a HeadRoom Total AirHead. I later added an HD650. They were also very good headphones. However, I struggled to hear a rationale to keep both, as they didn't sound materially different to me on fresh pads. I ended up selling the '650s here.Just bought a second hand HD580 Precision again. Assumed to be the 3rd iteration.

Is this compared with silver screen HD600 and HD650 or older black silk ones closer to the time of the HD580?Just bought a second hand HD580 Precision again. Assumed to be the 3rd iteration.

Wasn’t “Jubilee” the model that turned into HD600 after the collectors run was finished, with extra “for collectors” stuff?Yep, the Precision. The Jubilee is rare and sells for collector prices where Precision usually is sold for 2nd hand prices with decayed foam.
Silverscreen HD600, silverscreen HD650 and this black screen HD580.
Most of the differences are not so much caused by the screen but rather pad condition.
It's not the same nor better nor worse but very close to the HD600 and HD650 sound and measurement wise.
The paint job (lack thereof for HD580) and slightly different tuning are basically the main differences.
Those that find the HD650 a bit too warm and the HD600 a bit too cold and don't care for paint should look into HD580 Precision.
It is a hair 'brighter' than HD600/650 though.
