The problem could very well be that you're trying to shove them too deep into your ears. I recommend the stock tips with a somewhat (but not too) shallow insert for best possible fit and SQ, and trust me, they won't fall out. I find the Meelectronics triple flange tips to be uncomfortable and to change the sound signature and not for the better. Also, I find no advantages or real disadvantages with the Comply TS-500 except the inconvenience of having to roll them between my fingers before insertion.
I was to write about the tips, since I received the complys and the meelec .
The meelec makes the soundstage wider imo, but thinner note weight in comparison to the stock tips..these are of course to my ears.
Another thing, the meelecs while being super soft, seemed to isolate poorly. I got the large size trips, which fits like a medium for me.
The complys, as you say require tip rolling, and imo makes the signature a bit dark, which helps with some music content. But the body housing
is what poses as the achilles' heel to my ears.
At the end of the day, I found myself reaching for the stock tips for comfort sake. IMO the 3003s with the stock tips work well for my ears
for a couple of hours before the notch of the steel housing( the bend profile of the steel) begins to hit the ear sides. As far as insertion depth, maybe I overdid it, but I would constantly realign, rotate to ease the discomfort. Will try a shallow insert as well . I love the sound and want it fit like a glove in the end.
