Adding more confusion and surprise to this saga, the K270-Studio badge appears to have been adhered with the original adhesive. 

 

I was able to slide an x-acto blade under the edge and then heated the badge with a heat gun until the adhesive was soft. It really looks like the adhesive was original. 

 

The screw that holds the cap onto a k270 or k280 is off-center, so i am truly baffled. 

 

The molded plastic around the headband wires on the left side has broken free on both sides. I've had good luck with epoxy on these in the past, but never one this bad. Gonna give it a shot. I think i will buy some new for-plastic epoxy though. 

 

OH, now i get it. the headband was broke or they broke it. They twisted the cup off of the screw in the headband end. OW OW OW OW OW!

Is K270 closed back and K280 semi-open back?

 

I was digging through manuals because it turns out that one of the drivers in my old 270 playback has a blown voice coil. 

 

in a k270 the upper and lower drivers are different part numbers, and each is fitted with a different white rubber thing on the inside which the manual refers to as a bass resonator. 

 

in a k280 the upper and lower drivers are identical, and there is no bass tuning thingie in the parts list. 

 

I'm gonna have to call Frank and ask if k270 playback drivers are available. I don't have high hopes :(

That helps explain why the K270 is generally held in higher esteem than the 280 which I didn't like so much.
