Terminology, guys, please
As Some Beggar bangs on about, these reviews are close to useless as they only use subjective language. Please study up a little on audio. Something may sound "cystal clear on the high frequencies" because of non-linear distortion (some manufacturers even design for it, as it makes highs seem "brighter", good for the department store quick listen, but quickly gets fatiguing for longer listening).
At the very lest get terminology right - a speaker or phone is not "louder" than another (which is a function of how much power you're putting into it), a driver is more or less "sensitive" than another (i.e. efficient at changing electrical energy into mechanical energy into accousitc energy), measured in dB/W/m
