Question regarding headphones and battery life.
Does it take more battery life out of an mp3 player to drive certain headphones than others? Like for instance a pair of IEM's than a pair of full sized over the ear headphones?

impedance is resistance(load) the more load you will attach more fast your battery will drain.
Someone having more technical knowledge can elaborate more about impedance and sensitivity of headphones. Still,it is interesting that I could easily drive Audio Technica AD700 with Fuze+ whereas I felt need of amp to get proper loudness out of Senn HD 202.
