Maybe I should've posted some extra info.
Even though having my IEM's insides protected would be nice, my ears aren't a wax factory and, I usually clean my ears before putting my IEM when I feel they're dirty. I've also carefully cleaned my IEM's filters several times, blowing away what I can and, carefully picking away any debris with a needle.
Still, the extra layer of protection would be nice if and only if that layer won't get ruined during cleaning.
Also, new questions!
What are those filters made of? something like the foam-y stringy filters that my IEM already have? Something fabric-like?
Will that material be easy to clean with, lets say, blowing in them, or using something wet or direct water?
Actually, I'm leaning towards the TSX because, replacing their filters would be easier than replacing my IEM's (by just putting a new set of tips on them) but, if those filters won't survive some cleaning (like my IEM's have done so far), the extra cost wouldn't be worth it.
