......ok, here is the dumb question of the day (exposing my novice status). Is there a fundamental difference in the electronic components of a Closed End Headphone versus an Open End Headphone....... or is it simply the casing is designed differently. I do understand that there is a difference between the two when in comes to quality..... but are the guts inside the same, and it simply is the shell that is making the differences???
(told you it was a dumb question)
