I have recently become concerned due to a popping noise from my setup (EM-U Rosewood wBlack Dragon cord/Cowon P1), similar to the staticy noise your headphones make when you insert them into a jack. It is very quiet and short, and is only audible in low volume, but it doesn't appear to affect the audio quality. I have tested my headphones on other DAPs and vice versa, as well as changing cords, and the noise only happens with this particular setup. I should also note that it only happens occasionally, specifically when I move my cord or pick up my player to switch tracks. Anyone have a guess of what could be culprit, and if it's worth being concerned about?
