I am so happy everyone else has tried the filter removal and is liking the new sound! I was worried I'd become the new SM64 pariah who told everyone to break their IEMs! Doesn't the sound just "open up"? It sounds like what the IEMs were supposed to sound like... As if with the filters in, something goes terribly wrong, and ES actually tuned the IEMs to sound without their filters (the sound is a lot less muffled and congested, the bass is not as floppy).
I didn't know about the filter removal tools, but if there are some, that is great. However, the moment I took the filters out, I put them in a Ziploc bag but even told myself "I don't even care if I lose this bag, because I know I'm not going to be putting the filters back in." The increase in SQ is so substantial.
Glad it's working out for you guys. Only when I removed them did it really start sounding like a top IEM... The rest is playing with tips.
