Matching two different charts one against another is a problem especially when they are from different iems with different types of tuning like flat FR vs v-shaped... SInce i measured Blons 1 week afer BA5s level matching was nowhere near. BUT i can redo my measurements tomorrow for those two very different iems (DD vs 5BA) based on same input dB readings on software effectively matching them from SPL level and we can check actual overlaping of FRs.
