I have collected some K240M.
the first version:

the golden band of firs version M

the second version:

and as for K240DF,the driver varifies as in different version of DF.
the first version of DF:

the second version of DF:
compared with the first version of DF, the second version is only single cabled and the driver is the same.

the left is second version of DF, the right is the third version
the third version and late version:

Are you shure, the double cabled has the original cable? It looks like recabled for me.

the df with monitor baffles is pretty interesting, maybe akg just does whatever the hell they want and puts the current model badges/decoration on

can you take a pic of the dual entry k240 y split in the cable?

it seems like the one on the right would have to be the earlier version, because it uses the Sextett Baffle. The one on the left has a newer, redesigned baffle.

Sound differences? That's the most important thing

The difference isn't huge. I like both better than the K240M and I like the DF better than the Sextett. The Sextetts have the most bass. The DF has the flattest FR. All of them are 600 ohms so much harder to drive than the MKII. I've not heard the S or MKII so I don't really know how they compare. Most people who have heard both 600 ohm and newer ones tend to prefer the 600 ohm ones.

Thanks

I used classic to intend the ordinary version of the 240 (S and M actually produced) not the "special" like DF or sextett. From what i know these version are much different by the ordinary production of 240s, isn't it?

I've already tried to remove the material that covers the holes, i've noticed only more strenght in the highs

 

[scompton]

From what I've read, the big difference started with the S. It was the first non 600ohm one. I've owned all of the 600 ohm ones except and EP Sextett. They sound quite a bit alike. The differences are noticeable but not huge. Most non-enthusiasts probably couldn't be bothered to listen for the differences.

A technician at AKG told me they use the same driver for the K240s. The main difference is the design of the inner baffle and other small tweaks, so I would think they sound largely the same.

leave it to AKG to produce the same headphone for 40 years and have the world thinking it's a new design! now that's good marketing.

I'd love to hear an M version sometime. I agree Scompton, in my experience with the Sextetts, the differences between different units can be more than the difference between the models. Unless of course the EP actually is that much better. But no one else seems to think so, so I chalk it up to random goodness

I just got a brand new K240 M in a trade. Even without a proper amp I and getting decent sound. I am going to build a tube amp and then I will be able to see what these are capable of.

Yes, they can be driven quite effortless, despite the expectations.
