Okay, I'm not an audiophile, but when I listen to the S4's from my iPod Touch, the songs have a static noise. I don't know if its static or not, since I never experienced it. I will describe it. It sounds like scratches, like you scratched something lightly, and it happens randomly at certain parts only and when a high pitch drum is hit. I looked it up, and people recommend to switch the source of music, so I tried it on my computer, and it works perfectly. If it's my iPod, anyway to fix it?
I also need help, do I need to burn them in? And how do I burn them in/how long? I just got them yesterday.
