Hello Markt,

Timtim : great insight.

Just substantiating to what Timtim has said above. As you already know that human brain is divided into left and right hemisphere and each hemisphere has difference characterisitcs as given below. The left hemisphere style is more rational whereas right hemisphere style is intuitive

Left Hemisphere
* Responds to verbal instructions
* Problem solves by logically and sequentially looking at the parts of things
* Looks at differences
* Is planned and structured
* Prefers established, certain information
* Prefers talking and writing
* Prefers multiple choice tests
* Controls feelings

Right Hemisphere
* Responds to demonstrated instructions
* Solves problmes with hunches, looking for patterns and configurations
* Looks at similarities
* Is fluid and spontaneous
* Prefers elusive, uncertain information
* Prefers drawing and manipulating objects
* Prefers open ended questions
* Free with feelings

As a result what you hear in your right ear is directed towards your right brain and what you hear in your left ear is directed towards your left brain respectively. Therefore IMHO you wouldn't receive positive results if you interchange the left and right headphones.

Maybe Alex, Pete or Paul would like to give a better answer to this.

God Bless you

Kind regards
