It's so easy, but did you ever test for the optimal position of your headphone? With many headphones the soundstage and the balance of sound are strongly dependent on the position of the driver to our ears.

Scientific research has shown that our perception of depth is increased when the driver is placed more forward and lower with respect to the entrance of the ear channel.

Experimenting doesn't cost you anything and may improve sound considerably.
