With universals, I can't seem to get an even balance where the sound is perfectly centered. I don't have symmetrical canals, and I'm pretty sure my eardrum is set back further/deeper on my right ear (or the 2nd bend is further back IDK). At least CA cut them this way. The right is visibly longer-stemmed than the left. Not that I can feel this, which is great. They both just lock in there like a charm and don't exhibit pressure in the canals.
Anyway, I finally know what it's like to have balanced sound without using the "L/R balance" feature in my DAP.
