So wait, if you swap the speaker location, the problem follows the speaker, or the problem stays in place?
Hearing tests are good too! One thing that goes on with me is I get far too much wax buildup, quickly. I have to rigorously use a body wash and rinse my ears out or within a couple of days my system’s channel balance starts to shift. My right ear seems to produce more wax than my left, but this may have to do with sleeping positions.
