Almost the same just mine are not opened type...they are without holes...and they have old 5 din jack...

They appear to be the closed-back 'sibling' of the DT440 and DT441 from 1976.
I've never seen one of those before. Very cool.

Going by the size of the DIN plug strain relief, it doesn't appear to be stock... but I could be wrong.
It might be an obscure studio variant.

The DT440/441 specs should be quite similar, since they look similar and are from the same model number range.
So take these values with a pinch of salt... only the imdepance can be easily verified with a multimeter.

Frequency response - 20-20kHz
Sensitivity - 113dB SPL
Impedance - 600 ohms

When i bought them they were connected to some profesional mixer...so i belive they are studio headphones(because of the 5 din connector) i send email to beyer dynamic customer service...and after few days they answer that they didn't made dt 441 or dt 445...so i was like What...i didn't want to belive that someone made fake beyerdynamic 40 years ago! Thank you so muck for this information
Maybe i have holy grail :-D

Yeah...I remember mixing up a 5-pin-din midi jack with a 5-pin keyboard connector as a kid...definitely for the 90s kids.

You will need this adapter and put a 3.5mm-to-6.35mm adapter on it to use it on almost any other amp with a 6.35mm jack:
