Used similar trick with my ED9 tips as mentioned in above link but with leftover foam tips (I don`t like and use foam tips):
It gives kind of "mushroom" shape to silicones.
Now I use smallest KZ "whirlwind" tips which I find very good for ppl with small ears/ear-canals. They have very large bore and good fit for thick nozzle IEM`s.
Best silicones for my KZ ATE so far and probably will be unbeaten in case of ATE for me.
Here is my small ear/ear-canals silicone tips collection that I personally find very good:
From left to right:
1. Ultra soft gel-silicones. Bought from here (white small): http://www.ebay.co.uk/itm/Compatible-With-MDR-EX-Series-Ear-Bud-Gel-Tips-Various-Colours-x-6-Pieces-/391207005098?
2. KZ "whirlwind": Bought from here: http://www.aliexpress.com/item/KZ-3-Pairs-L-M-S-In-Ear-Tips-Earbuds-Headphones-Eartips/32333783387.html
3. Piston2 smallest tips that come with original Piston2.
4. KZ ED9 smallest tips that come with black plastic boxed ED9.
5 & 6. Soft triple-flange silicones. Bought from here (clear): http://www.ebay.co.uk/itm/281672238091?_trksid=p2057872.m2749.l2649&var=580677706162&ssPageName=STRK%3AMEBIDX%3AIT
For KZ ANV, I find so far best fit and SQ with silicones from another KZ IEM - ED9 medium grey ones.
Triple and double flanes are also ok but by SQ little less good. Medium triple-flanges go littlebit too deep (little irritation), have small bore and too long/wide/low "skirt" that covers breathing hole, which affects ANV sound too much. Double flanges are actually cut out of small triple-flanges, have medium size bore and elevated lowest flange which doesn`t cover breathing hole, resulting better sound than medium triple flanges. Those triple and double flanges are still very soft and good for other similar nozzle shape/length type IEM`s but just not so good match for ANV sound.
For KZ ED9 I found best solution with #1 white gel-silicones because they are ultra-soft and ED9 with its small body and quite long nozzle requires deep insertion.
I used little spacers cut from sony hybrid and ED9 tips necks to keep those small tips more on top of nozzle to leave nozzle breathing hole totally free. And being ultra-soft, lets them "contract" deep in ear-channel.
What I still want to try some day are Spinfits. Also, I have interesting tips incoming soon with this IEM (bought only because of tips): http://www.aliexpress.com/item/Huawei-3-5mm-earbuds-dj-earphone-Bass-with-Mic-noise-isolating-Headset-earphones-earbuds-For-Huawei/32378986602.html
