You are joking right? If you have to swap them out so fast to tell the difference then there is probably not much difference. You need to play music that you are familiar with or that highlights different instruments or vocals and listen for a while before swapping them out. I agree with what Elizabeth said:
BAD IDEA. Better to listen to one for a few days. Then the next and afterwards think if you liked one better than the others that way.
Happy Listening!
