Problems with some iPod 4G and iPod Photo

iPod Lounge has collected many reports concerning an audio defect which "can be heard in headphones when the iPod Photo's hard drive reloads its music memory buffer, and sounds like static accompanied by hard drive accessing noises, overlapping for several seconds the beginning of a music track". The problem seems to be present only when using a third-party head-phones with a non-protected plug. A temporary fix consists of adding a small piece of plastic/insulate between the iPod and the headphone plug.
