Is OP me? battery life isn't supper important, i just want to get threw the day of listing with an ipod with out the battery dying.

any speaker to test. i do want it to still sound good (not amazing, jut good). the headphones can easily be redisigned.

sorry i got mad, that was real stupid of me
, i need all your guys help.
Those specs are unimportant. What's important is the driver's frequency response and distortion values. You'll probably have to measure those yourself.

This. and transient (impulse) response.

The OP has asked how to work out a headphones power requirements because of concern about battery life, how exactly do you think freq response and distortion relate to battery life?!

I know this. The OP clearly didn't and was willing to select any speaker as long as he could fit it in his headphone design.

yes and my point was that the response in the headphone not relate terribly well to the published spec in isolation, the spec outlined in the datasheet will match when the testing conditions are replicated, to within specified tolerances, IF theyve done their job properly. its a specification to base your modelling on, not something that is likely to be replicated in the headphone without serious testing. the effect of the headphone on battery life is not to be discounted either. if you build with 32ohm highly efficient and often quite boring drivers sure they are efficient, however even the efficiency in the cup cannot be taken for granted to be the same as in isolation, especially if its a closed back design
crap headphones can easily be made out of great drivers, just like with speakers. not as much so since theres no crossover in most cases, just ask the thunderpants crew, which btw is a perfect example of a headphone that will have profound effect on the battery life of the player its used with.
