"Golden Ear" is also the technical term doctors use for cases of extreme ear wax buildup.

I wasn't able to find anything on the Internet to substantiate your claim.
I was able to find plenty of information to the contrary. For instance, an excerpt from https://en.wikipedia.org/wiki/Golden_ear
"A golden ear is a term used in professional audio circles to refer to a person who is thought to possess special talents in hearing. People described as having golden ears are said to be able to discern subtle differences in audio reproduction that most inexperienced and untrained listeners cannot. Another meaning of the term is used by audiologists to describe aging test subjects who do not demonstrate the expected age-related loss in hearing acuity."
