Blind Tests

A "blind test" is a method of testing in which the people being experimented on have no idea about what they're getting. This test method prevents results from being influenced by any a priori information. In the field of Audio, blind tests truly highlight what a listener is able to hear.

In the so-called ABX blind listening test, the listener has access to three sources: A and B are the references, X is the mystery source. X can be A or B. When the listener says that X is A, and that X is actually A, it doesn't prove anything yet: flipping a coin achieves the same result half of the time anyway. This is why we provide the listener with many trials to determine if the number of correct answers is statistically significant.

My Recommendation

If you are looking for pretty nice headphones, here is my favorite in terms of 'best value for the money' : the HD668b. If money is not an issue, try the HD600.
