Hi, yes these are air pods model. I have a good fit with spinfit cp 100L but cp 1025 ML are too small for S12 (but good for KZ DQ6). I will try with L size later, and you better have dry ears!What type of CP 1025? there seems to be air pod model and wireless model. So you think CP 1025 sounds better than CP100?
But this not night and day. I just find that latex eartips (Xelastec, CP 1025) provide a bit more textured sound and, also a bit more cleaner. Spinfit CP 100, and 145, are easier to fit as they forgive size errors.
