maybe somebody said it already, i would repeat it: stock earphones of 99% cellphones, smartphones, mp3 players and airplane earphones. i would put monster studio pro to that list, not the sound. The phones sound really really good and it is very balanced and it would be my only headphone, if not this heavy horrible fit. I could bear it only 10 min and the pressure on my ears became unbearable. i have sold it within a week. Although i have relatively small head. Nonetheless, I am huge fan of the turbine gold and copper.
