I got an AKG K121 Studio headphone for repair in the following condition:
I don’t know what would happened with them. I think it just simply come apart during years. Since AKG headphones are Made in China plastic parts are broke, cable became stiff etc.. I never seen Made in Austria version come apart or with broken plastic parts.
After ~5 years of usage my favourite Beyerdynamic DT770 pro (250ohm) headphone’s headband sliders started to get hairline cracks. I read forums about this problem, its a very common issue. Original replacement parts also will crack so this is not the best solution for long term usage.

After more than 10 years my emu 1820m started to play noise when i tried to play music. Sounded like “white noise” and 15 minutes after every boot the noise seem to be disappeared.

I bought new rubber feets for my emu 1820m audiodock because the original rubber feets are missing. I found in “Dome Bumpers” or “Bumper” names at my local DIY store. The bumpers are self-adhesive so you can easily stick to the bottom of the emu.
