Just thought I'd throw my two cents out there. I have the international i9500 version of the galaxy s4 and it was kind of irritating me. The camera was slow and buggy and the phone heats up intermittently.. Not to mention samsung botched the implementation of big.LITTLE... I decided to buy the i9505, which has a good camera, is as fast as the octa and doesn't overheat.
Anyway I listen to music all the time (I listen with the Shure SE535s at the moment). All I have to say is that the DAC in the i9505 is rubbish compared to the Wolfson 8740 in the i9500.. For this reason only I have decided to keep the octa and ditch the i9505. I don't mind living with the little flaws in the i9500 for the sake of the amazing sound it outputs. And I mean the difference is huge.
Just a heads up for anyone thinking of getting an S4 and who listens to a lot of music through head / earphone.
