Help me identify these Beyerdynamic DT 880 - what year, impedance?

Hi all!
Trying to identify these Beyerdynamic DT 880. I would guess they are from the 80's? Anyone know what version this is, how does it sound, impendace?

If I remember correctly, I'm pretty certain these are the 1993 version.
I'm not sure if there were more versions aside from the 600 ohm back then.
Only way to tell for sure is to use a multimeter on the plug.
I've only heard an 80's version + OEM variants and a few modern ones, so I can't say how it sounds.

Thanks! That’s more than I knew
