I can't stand off centered imaging either, it is incredibly distracting.this is interesting. I've never tried any double flange before and your impression makes me want to buy them now. anything other than CP145 sounds weird especially on the hi-hats & vocals to my ears. sometimes it makes me wonder "is this one of the best tunings that people talked about?" haha. aight I will try to look at the previous 126 pages just for some tips recommendations.
and I hate that my pair don't give the proper stereo image or 'centered' sound stage projection. it seems like most vocals, snares, kick drums, basses, are a bit leaning to the left. there's some 'hollowness' on the right side of the stereo field in between the middle and far-right panning point. reverb, 'airiness', decays are a tiny bit lacking to compare to the right side. sometimes I feel like one of the Sonion EST is not working properly in the right earpiece. it's still working and listenable but somewhat 'lacking' and it's kinda disturbing sometimes.
I usually test IEMs with this site: https://www.audiocheck.net/soundtests_headphones.php
Theres a test that does a full frequency sweep, and the image should stay centered across all frequencies. This way you can tell if its your IEMs or your playback device/audio file recording that is causing the issue
