Oh wow, I never even thought of something like a tea/coffee filter, that's a great idea! I think it might be thinner than the material AKG uses, but in situations where it makes a more noticeable difference, one could always just add additional layers until the desired result is achieved.

nope, I haven't tried anything else so far.
My sister is using the pair I did the tea filter repair on and so far, she hasn't had any problems, as far as I know.
I don't think it sounded different from the pair I'm using which still has the original fabric on the baffle.
According to AKG, all spare parts should still be available though, so if you're in doubt, you could replace the baffle - but then... you can still do that after trying to repair it :-)
While you're at it, you might want to remove the reticulated foam that sits between the baffle and the cup. It had started dissolving on my phones and I didn't want any sticky goo falling into the drivers. This piece of foam should still be available as well, but the phones will probably function almost as well without it :-)
BTW... I just got a K702 some weeks ago to compare to my vintage AKGs. It is really good, but trying it has even increased my respect for the older designs such as the K 280 and the K 240 DF. These designs from decades ago are still very good performers in my opinion.post #19 of 236/21/12 at 1:28pm
Cpt. Klotz (and of course everybody), the foam ring inside the ear cups is still available from AudioPro and RW Soundsystems. The little foam thingy that sits directly under the earpads, however, seems to be out of stock at both distributors. You could always call in Vienna, however, I'm not sure if they have it. Anyway, I could imagine that simply cutting a replacement from thin felt would work, but I'm not sure if it's necessary to have that part at all.
On the other hand, I'd like to upgrade mine to velours pads pretty soon, so while being at it, it would make sense to also do those foam rings.

Yup, that's exactly my experience... The foam ring that sits under the earpads is not available anymore according to Audio Pro.
I just took the foam disc that's meant to go inside the K240, cut out the middle and stretched the newly created ring. Cutting a ring from a larger piece of foam or felt is probably a more elegant solution :-)
Not sure what purpose it serves in the K280 anyway (comfort maybe)... The K270 doesn't have it, and in my experience, a good seal is much more important for the K270 since it is a closed design (the mids sound hollow and honky without a good seal).
The reticulated foam that sits in the cup should certainly be available... The current K 240 still uses it (it's probably the exact same part).post #21 of 236/22/12 at 3:27pmpost #22 of 237/28/12 at 3:35pm
So today I finally got around changing the foam rings inside my K280 and my K240M. While removing the old, rotten foam, I noticed that the thin paper membrane on the K280's right side has a small perforation. Maybe I was simply not careful enough or it has been there for some time - I don't know.
To my ears it still sounds good. Should I be worried about that little pinch?post #23 of 234/13/14 at 1:59pm
I agree with you on the sound of the K280. I find it to be skimpy on bass, but unrivaled on the top end. Of course I have the same problem that most have had with the inside vents being puctured, but I used a tiny bits of fabric tape to patch it. Not as good as the tea bag idea that some have used, but it was all I could think of back then. A couple of years ago I decided to compare the audio on these using a well known test frequency playback DVD that I imported into Pro Tools and played back through my mbox to compare the AKG K280 Parabolic (75 ohm) to my AKG K240M (600 ohm) and BeyerDynamic DT770 Pro (80 ohm), plus whatever else I had laying around (Bose QuietComfort 2, and Vmoda earbuds). I was surprised to find the K280 able to reproduce the highest frequencies, while none of the others could. Conversely, I found they whimped out in the bottom end, where the BeyerDynamic DT770 really shined. I performed the exact same test again, this time using an Edirol 24/96 interface and Audacity. The results were the same. After discovering this anomaly, I have since used the K280 as a "go to" set whenever I need to check the top end on something. Another use where they really shine is on vocal recording in the studio. The added "air" on top and conservative bass response, in combination with the dual diaphrams (which help trick the ear into thinking your are in a room) are helpful for singing "on pitch" while monitoring using these cans, if you happen to be one who's ears are more sensitive to this.
