When working out on my last day of holidays my right TDK BA200 got muted when i did what you never shoud do when working out (take out the iem to listen to the missus and then reinserting again. Squeezing a wet Shure olive is like dropping a glass of sweat onto the acoustic daper).
Since 48 hour buried in silica gel did not solve the cloggging i bumped into this thread. Somehow i manage to take out the clogged damper (with an allen wrench) ruining it in the process. To my delight the sound pressure level got back to normal. I had and spare white damper that Shure sent last summer (Yes, Shure can send dampers if you cry enough). I put it in and the BA200 were usable again with the caveat that the soundstage was bit tilted to the right (since the left piece still used the Sonion red 2200ohms damper).
So i ordered from Eytmotics the removal tool bundled with 4 green filter. I placed them and now the BA200 are rocking and with better treble than with stock red damper.
Bottom of the story: this mod works on the BA200 as well. Actually it saved mine.
Thanks to everybody involved.
FTR i tried to fiddle with my acting up Westone UM3x-rec dampers but it did not look feasible to take them out without destroying them and endangering the nozzle. Since i'm sending them in for repairs i did not want to break anything and gave up.
