The edges aren't all the same thickness, but it isn't noticable.
For tubing, I used 1/8" heat-shrink tubing. It was ever so slightly too big for my shure e3's (enough to make it slide on the shaft of the e3's), so I had to resort to heating the tubing (not a fun experience, since using a lighter under the tubing resulted in irregular tubing shrinkage (you know what I mean ;P), making it a bit messy to fit onto the shaft of the e3's). The tubing is also very thin-walled, which initially worried me, but I still was able to slip it on the e3's without trouble.
For making the holes in the foam, I jabbed a hot nail through the (non-frozen, non-flattened) foam - it seemed to do the job well enough.
Then, I simply pulled the tubing through the foam with a needle. No glue was necessary, because the nail wasn't hot enough to make the hole in the foam visible all the way through, so it was nice and snug.
The finished product looked a lot more neat than I thought it would. I'll post pictures soon.
The comfort was much better than the given yellow shure foamies, and there was a lot more isolation (although my yellow foamies are very old, so maybe not the fairest of comparisons). Not surprisingly, the bass was more present, but the overall sound seemed to lack clarity (which probably can be solved by making the tips shorter).
UNFORTUNATELY, my right foamy kept getting stuck in my ear as I took out my e3's. Obviously, I didn't shrink the tubing enough, which is a big pain in the butt. Now, I'm going to try to find some regular tubing to use instead of the heat-shrink tubing - it just isn't worth the hassle to heat them up, etc, especially if they're going to fall off my IEMs all the time.
EDIT: I think I might try out GravY's mod; it looks like a pretty solid idea, and easy, because those are, once again, the same foamies as mine .
