Okay, so firstly, 'volume limit' is off. When listening via earbuds, the volume control gauge is in the middle, it's faint. Pushed all the way to the right hand side, it's loud but hardly 'blow you away' loud whilst listening to podcasts (non-music). With music, arguably, the last 2/3 notches are probably loud enough to use for music (without causing damage to my ears). Maybe I'm missing the obvious (as this was the same as it is on my IP4s as it was on my 3GS) - but what's the point in the rest of volume control if 80% of it is practically faint? There's no calibration with itunes re: volume...is there? There's a good chance I'm being OCD with this.
