Hi, i'm searching info about this headphones that i found yesterday among some old stuff that my uncle gave to me. First of all, sorry I'm not German and I can't speak German. I hope this doesn't cause any problem to you. Then, i'm trying to figure out how old are this headphone. I literally can't found anything on the internet about their release date. I found only the user manual, but I don't see any reference on it. Can you help me? Maybe you got this headphones in the past so you know much more about them.
Thanks in advance
