I've done this to the KSC50's a few minutes ago, but I just carefully pulled the foam off it. Problem is that it's not getting on very well anymore. How do you open up the KSC50's?
Weird bass, maybe it's the song, the bass seems, uh, just not well there. On lower volumes, at higher it's there, very clear.
I love piano with these things.
On a side-note: The foam is perfect for modding EX-71's to have less shrill highs. Put them in the foam/soft flex sleeve Shures way and put a new types of fitler in
