Does anyone have information about the AKG K3 "dual dynamic system" of the intriguing and stylish K1, K2 and K4 series of the 1980s?

I used to own the foldable "scissor" type (Schere) K1, which sounded inferior to the contemporary Sony mini headphones (MDR30 etc), and sometimes listen to the electret/dynamic K4 despite the disappointing treble response.

Data & pictures of the K3 would be appreciated.

Here's some info and pics from the Japanese website Modern Headphone Museum: K1, K2, K3

That K1 is pretty wild looking!

Nice link. I just love the way AKG used to make such cool things.
That K1 headband is awesome.

I can imagine your hair getting caught in the K1 headband all the time.

Disappointing treble response on the K4? OK.

I have a K145 and i don't think I'd call it disappointing in the treble, but it's been a while since i listened to it.

Sorry for 13-year thread necro, but this page is still one of the top results for "AKG K3", and there really isn't much info on them elsewhere.

Here's some shots of the internals.
Note the passive diaphragm at the back, extremely similar to Pioneer's "Variable Chamber" system on the SE-11 line.

I don't have the right pads for these, so I'm not sure how they originally sound. The foam pads you see in pic 1 are performing pretty poorly, completely no bass, which isn't what i'd expect from something with a passive diaphragm. I think the driver needs a less permeable front volume, which was provided by the plastic cover you see in the last pic (the thing with the speaker holes sitting on the cutting mat).
