The drivers look identical
Regarding clips, there's none from what I can see... it looks like there may be glue involved or some kind of interference fit between the drivers and holder. Might just have to cut the baffle away to free 'em!
Hmmm... am I making sense here? All I received were the baffles with the drivers in 'em and the seller told me they were from a set of AKG K140 headphones. I'll try to get a photo up tomorrow as I just spent the last 5h hugging solder fumes and it's 1am--bed time!
They are brand new drivers from the k140, i sent them instead of the old ones as you will see there is no solder on the ok one.
It,s just a matter of getting the glue off as i did not want to attempt it as i am fairly new to this stuff.
When you get them out you should be able to use both of them as the broken solder lug will be ok in the sextett.
I would put the one with L on it in the right cup and the other one in the left as the one with L on it is a lower impedence than the other one, this is what i have done on my k140 and the impedence is matched on both cups due to the metal headband adding
around 25ohms .
As for the glue it looks like the same browny coloured glue they use for the nameplates on the side, so try the hairdryer method or fire fitz or boilermakerfan a pm.
