So what is the point in having a "Flat" setting when it's basically just "Off"?
I also did a test where I made a equalizer preset for one song and basically just turned the bass all the way down and turned the treble all the way up. It wasn't to make it sound good (it didn't) but to see if there was any difference, and there wasn't, on the Flat setting.
With it 'off', there's no equaliser. With 'Flat', the equaliser is on, but not changing anything.
The only difference is that, with it set to 'Flat', the iPod's battery will run down slightly faster. Having the equaliser on (even set to the very pointless 'flat'), uses slightly more power since all the songs have to be processed as they play.
