Different HeadSets for Listening Tests 2003-09-12 10:55:03 I recently bought a "high end" stereo headsets for my listening tests. Before this, I was using a "cheap" pair of earphone.. Initially I was surprised that my "cheap" pair of earphone "outperformed" the brand new stereo headsets. I was able to hear more details on the old headphone than on the new stereo headsets. Then after using the new stereo headsets for sometime, my ears seemed to gradually be able to pick out a lot of details which I couldn't hear earlier.. I seemed to need to "retrain" my ears on the new "high end" stereo headsets. Why is there such a effect? Is this some kind of psychological effect?
