About 10 years ago, I had a friend who went to the hospital with a terrible ear infection. He had a fever, his ears were nearly swolen shut, and he was in tears from the pain. I don't know why he waited so long to go to the doctor, but that's another story altogether. Anyway, the doctor looked in his ears, got out a pair of whatever evil plier-like tools were handy, and pulled a crusty, amber-colored rock out of my friend's ear. He told my friend that his ear infection was caused by cleaning his ears out with Q-tips and alcohol. In his daily regimen of ear-cleaning, my friend had actually pushed enough earwax and dead skin into his inner ear canal to form this pebble-like mass. Anyway, the moral of the story is that we have been evolving for quite a while, and our ears can handle this all by themselves. Then again, we haven't been judging differences in cables for all that long, and maybe this little tweak will help. You never know.
