The brain sorts it out. Information that is analytical is sorted by the left brain and the information that is creative, visual or metaphorical is processed by the right brain. While the Paraliminals are designed to make it easier for the left and right hemispheres to process the information. It is not strictly necessary. If you are deaf in one year you'd unable to function if the brain didn't sort it.
Notice your ear preference when you are on the telephone.. If it mattered one 100% you wouldn't hold the phone on the left ear when listening to logical analytical conversations. Some people do hold the phone to the right ear and swap when they have to write something down.
The Left and right ear listening is a recommendation. If you're not getting anything from the Paraliminal swap them around. Haven't you tilted your head make sense of a picture?
Occasionally you might want to turn the headphones around just for the hey of it.
