And there is actually nice history behind them:
I bought them from a man, whose father was working for AKG at the time when the K340 and K240 were produced. He (father) was given few pairs of headphones (k340, K141, K240) to test them at home. They were used only for few hours and are in perfect condition (without box and papers). His son was now selling about 8 pairs of N.O.S. headphones and I was lucky enough to get the only K340. Judging from the story they can be one of thr first models ever produced.
I'm listening them now and am amazed how natural the highs sound. I catched myself turning around few times, because I heard something behind me. I think they're bass heavy version, because I can't feel any lacks in this region. Amazing cans.
I'll try to post some pics later on.
