The iPhone 5 headphones are not for wrestlers and Judo players.
After years of using iPhones and Mac computers, I realized that, at Apple, there are no engineers with contact sports' experience like Judo, Wrestling, Rugby and Jujitsu. In those sports, athletes tend to break the cartilage in their ears, which generates the Cauliflower ear. “Cauliflower ear is a condition that occurs when the external portion of the ear suffers a blow, blood clot or other collection of fluid under the perichondrium”.
The problem is that the ear hole gets smaller. Unfortunately, none of the Apple earphones fit. In my specific case, if it was just for Apple, I would be unable to listen to music or have a phone conversation on my right ear. The same problem applies to most of my friends, as all are affected by this same condition.
Cauliflower ears have become a social recognition. It is common between men with cauliflower ears to exchange a few friendly words about their sport. At times, my cauliflower ears got me into a club or played as a deterrent to possible fights. It's a good rule not to get into arguments with people with cauliflower ears. They rarely fight outside of an official sports event regulated by sports rules.
