It's more of an earhook issue i think, my right ear for whatever reason doesn't let the hook get the 20s seated properly. The dual flange may work to fix this, i'll give it a shot, thanks!
You may want to give Frank’s horseshoe clips + earhooks from Aliexpress (mentioned in this thread earlier) a try. I found them more adjustable and fit my ears better, resulted in much improved SQ. They are a lot more comfortable as well.
