Comparison KZ ZS5 v1 vs. KZ ZSR
It is pretty obvious that, in order to remove the nasal/hollow, recessed mids in this very ZS5, one has to remove the prominent bump in the upper mids/lower treble.

B) Comparing different earphones with different tips can lead to differences, particularly in the bass and lower mids, but in all cases I used the tips that worked well in my ears with that particular pair.
