I think I've found the best tip ever for my SM3.
After following the advice for snipping off the excess foam from the regular comply foams, I was thinking, why not try the "do-it-yourself" foams that I found here.
So I bought some of the Mack's brand SafeSound earplugs, and went ahead and tried the process.
I had some yellow shure foamies lying around, so I took the core out of those. Then after several trial-and-error attempts (it's hard to get the right sized hole in the foam, particularly because they compress so easily), I was finally able to get the perfect fit.
Boy, do these sound fantastic on the SM3. With the core coming out a bit further than the foam, this allows the highs and treble to never get muffled by the foam. Furthermore, the seal is so excellent that it can barely be felt, and the bass is (to my ears) actually even more controlled and clean (not as muddy as with regular comply foams).
I think I've found my holy grail for tips! As you can see from the picture, the core is slightly protruding out of the foam, which preserves the highs and treble, while still delivering a clean, tight bass. Here is a size comparison to the normal "long" comply foam tips that I received with my SM3's:
The smaller size really allows for the fit to be perfect--I can't tell that they are in my ears. These tips are definitely the best I've used so far with my SM3's (even better than the double-flange silicone tips that I received with my first SM3 order--before EarSonics had so many orders on hand and introduced a new silicone tip). The best part is--a pack of 10 pairs of earplugs is only around $5. That is a ridiculous price considering the cost of Comply tips! If anyone has any questions, feel free to ask!
