This is actually funny. I bought the Triple.fi's because I was getting such a great seal and SQ in the store in HK using just medium silicon tips. Looking back, I remember that the guy was smiling at me until I realised that I had the IEMS in backwards. So I put them in properly. In the days that followed, I never got as good a seal again. I switched to big silicon tips then biflanges. I started looking at ordering custom tips.
Now thanks to the thread, I just did the flip flop mod as of last night - only this time switching the cables so the channels are correct. I'm back where I started with the medium tips. Isolation is incredible. (I couldn't hear the taxi driver talking to me in the cab this morning at all.) No fiddling around. Consistent deep bass.
What goes around comes around.
