Normal on mine. It does have more emphasis on the right ear at one point because it goes specifically into the steps of PhotoReading.
By any chance can you change the balance on your equipment? If it's uncomfortable for you you can adjust it. Software on the computer and many home stereos allow you to put more power to one speaker or the other. To make up for the fact it may not be possible to place them so the listener is equal distance from both. This adjustment affects headphones as well.
