Fit is proving to be a bit of a lengthy process for me too. I can't even seem to get the blues onto the Savanna as the stems bunch up. Couldn't seem to get a good fit with the reds either. Then tried ortofon tips which fit well but slide around the nozzle a bit. Sony hybrids can't stay on the earpiece. Currently using the bigger of the foam tips which are working fine while i think I'll pick up some spinfits. As an initial impression, I find the bass plenty on the Savanna and enjoy the presentation so far. Whether it will truly wow will probably depend on better fit. edit: Noticed that a few others in this thread have tried Ortofon tips with noble earphones. Any suggestions to keeping the tips in place?
