So I have spent a small fortune over the past couple of months to try and find the right eartips that go with the Lola's (in some cases re-ordering same tips but in a different size, if I got the size wrong the first time). By right eartips I am not so much talking about comfort here, as most decent eartips out there are comfortable enough. I am talking about the sound impact. I like the mids of the Lola , which are probably the best mids in any IEM out there, (even when compared to the Roxanne's), but I do miss the thicker sound of the Roxannes (and deeper bass). The perfect IEMs for me would have the mids off the Lola's, cleanly combined with the bass/thicker sound of the Roxanne's.
So after trying around 6 types of top-end ear tips (including the rarely found "Sony Triple Comfort" (which are made from both foam and silicone), the SpinFits, and the Symbios Mandrins, both "peeled" and "unpeeled", I came across a Japanese brand (Acoustune), which makes two types of eartips: AET08 and AET07. The AET08 are designed to focus the sound on "the bass reverb", as the company claims, and is meant to result in thicker and fuller sound. Well, to be honest, thats exactly what they do. For me they make the sound fuller, with bigger bass impact (but not bloated or muddy).I suppose they contain low frequencies better (they don't leak out or dissipate), and don't accentuate the higher frequencies (but they don't mess with high frequencies either). Its apparently to do with the material of the inner tube. The other one the make is meant to make the sound clearer at the high end of frequency (and not bass focused), but I have no interest in order than or trying it since I am nor looking for that type of sound.
If you are wondering why I simply didn't increase the bass on the Lola's bass pod (to try and make them closer as possible to the Roxanne's bass-wise), well I tried that at setting 3 or 4 o 5, but they end up being too bassy, and not in a good, clean, natural way. With the AET08, I can keep Lola's bass pod at the ideal setting of 2pm, and let the eartips do the rest of the "heavy lifting". I suppose you can call the eartips the last link in the chain of sound to your ears.
I feel now I have a pretty much near perfect sounding set of IEMs.. (well at least until the next greatest IEMs come along
These eartips are not easy to find on common English online websites, but are mostly sold in Japan and Asia. I ordered them from Amazon Japan (you can select English language for that site, which just about makes it easy to order). Or you can look to buy from Hong Kong. You can just google "Acoustune AET08". In any case here is a link where you can find these:

Also, here is good review of various eartips, which first alerted me to these (plus I tried a few of the others reviewed).
