Fischer Amps Silikontips triple flange

I can't complain about the manufacturing quality but unfortunately those were way too small for my ears.
To try give some kind of reference of what suits me, I usually use "medium" sized tips and I've used triple flange tips before that were included with my old Sure 215K. I found them to fit perfectly and they damped well and without sliding out my ears after a while. Was hoping for a similar experience here but unfortunately had bad luck.
