It seems like I am having this problem when listening to FM radio only, as far as I know, XBox music player is OK, it may seem like there is a problem with the earphones wire, but I've tried two earphones, same symptoms, the sound/audio changes, there is irregularity, or erratic audio level differences between right & left earphones, specially when there is movement, I tried shaking the handset and I got that symptom, when the earphone wire shifts, it happens too. sometimes it gets really low, then really loud. I am not sure what to do, it's quite disappointing.
PS: well, I know that this effect may be due to signal irregularities, but I didn't get that with my old Nokia 603, or Samsung Galaxy S3!
