Imagine that you went to Mars, where you discovered that the beings who live
there don’t have the portable music player. They’re still using boom boxes.
You realize this is a huge business opportunity and start selling portable MP3
players (except on Mars they’re called Qxyzrhjjjjukltks) and compatible

Picture of a stereo headphone jackBecause you control the player and the
headphone, you can ensure that your player works with your headphones. This is
a ONE TO ONE market. One player, one headphone.
