Woah,
turns out the uncomfortable, mediocre sounding headphones that I've had lying next to me for a few years were actually Beyerdynamic DT990's that were made in 1985. Guess I'll just fix the padding and hope that we have an amp lying around for these 600Ω cans somewhere..
these cost over $200 $350 when they were released The reason why I haven't been content with these is because they are uncomfortable, so if I succeed in refilling the pads with something, I'll probably be spared from buying new headphones for now.
Edit: I found something nice (it's from a timeline)
1991 The DT 990 - Voted "Headphone of the year" 5 times in a row..
