Headphoneus Supremus
I found these headphones in a fleamarket and only bought them out of curiosity and their superb condition.
I scoured the interwebs for any information on them, and came up with basically nothing; not even on these forums.
I found one link and one link only on these phones, to a set currently being sold on 'fleabay' describing it as "high-end" from 1974.
When I first plugged them into my computer for a good 'audition' they had very mild details, subtle bass, but quite a fair amount of mids, dynamics and presentation.
After trying out a variety of genres I found that only jazz sounds excellent on these. Then after a while fiddling with EQ I was amazed at what kind of sound they produce.
(Just for comparison reference, I've also got AKG K141 (original), Sennheiser HD450, some old cheap Technics RP-F200 and Grado SR60i (mesh grill mod, vented, +L-Cushion and cable mod))
Compared to all of these, I'd say they have the 2nd most exciting sound next to the Grados. They have a deep warmth in the mids, and a bass that doesn't kick like the Grados, but kinda rumbles with authority, which the Grado doesn't do. Also the bass has a certain quality that simply doesn't exist in the Senns or Technics, probably as these are 'consumer' grade phones.
Highs are very subtle, probably due to the age and available technology at the time, but the EQ pushed way up reveals that these drivers CAN handle being pushed hard and produce relatively crispy details.
Normally I wouldn't have bothered writing this up, but the sound these things make is a bit too serious to not find out more.
So, is there anyone here who knows ANYTHING about these headphones? Anything at all?

so clearly they were intended for the German market.
Here are some photos. (sorry if they're too big)

Though the only thing I have in the house that could drive one of these is my dad's receiver in the cabinet.
