btw: this is a DIN-plug, not XLR. sort of a predecessor but not compatible.

 

They sound like an interesting headphone for listening songs from the 60's and maybe 70's, but i never saw that plug before used in Audio, king reminds me of the PS/2 connector that existed on computers until not so long ago, but what devices used to have that DIN connector for Audio? i never saw any vintage stereo around here with that connector, and i must say i saw on eBay a K50 with the ¼" plug, modded for sure.

correct. for computer keyboards, this was the predecessor for the ps/2 connector until the early 1990s. for audio, it probably was mainly used in germany - DIN stands for "Deutsche Industrienorm" (german industry norm) after all.

 And is saw on some vintage documentation for this headphone that they are 400ohms, is that right? seem very high for an small open dynamic headphone...

Hi,

 

the DIN part is right - it's called a DIN Wuerfelstecker or DIN Domino plug and is a german special thingy but was standard for headphones over here at the time. Has some advantages too like being differential compatible, giving the user a choice of switching off loudspeakers or not depending on how it was plugged in and last but not least not shorting the headphone amp while plugging in...

 

But it went the way of the betamax...

 

Sometimes old AKGs come with an adapter to 6.3mm, if not adapters are available from ebay:

 

http://www.ebay.com/itm/6-3mm-stereo-jack-female-to-5-pin-DIN-plug-dice-20cm-cable-/321353148810?pt=US_Audio_Cables_Adapters&hash=item4ad223e98a

 

or you can build your own using the pinout here:

 

http://de.wikipedia.org/wiki/W%C3%BCrfelstecker

 

1 = NC

2 = left -

3 = right -

4 = left +

5 = right +

 

As for impedance - 400 - 600 ohm are quite standard for full size circumaural headphones like the K240 - especially if they are older. It's only 10 years or so that you see a lot of people using full size phones on the go, or not?

That's really interesting to see, if DIN had survived, would be great for home use, but it isn't really portable, so for the bad or the good part of it, DIN going away left the space to portable headphones become possible in the future, but one thing that got me really interested, this standard was used somewhere out of Germany for Audio?

It has been used in the Netherlands as well, see for example the Philips N6330 (made by AKG):

I've noted that many models of AKG headphones are rebranded as Philips models, did AKG and Philips have some deal in the past?

Obviously. But I don't know  the ins and outs.

Should be nice if someone digs a little deeper in their mutual history.

Seems like this information is very obscure, can't find anything that can give a hint.

AKG also rebranded for Saba, Uher, and Radio Shack.

Also the DIN plug has the advantage of being pre-wired for balanced amplification.

Saba and Uher, those are twi i've never heard, i  know that Radio Shack also rebranded Koss Headphones during the 80's, but never heard they did that with AKG too.

So the DIN plug during this time was really like a XLR connector, interesting.

Exactly, so you don't need to rewire the entire headphone if you want to run it balanced - you only need to make a balanced XLR adapter.

Technically XLR is like DIN since the latter is older... but tomayto tomahto.
