most probably thats the FAKE IPOD SHUFFLE that looks amazingly like an orig shuffle in box and headset, IT MAY EVEN COME WITH INSTALLER CD
FAKE IPODS are EXACTLY LIKE ORIG ipods, but when u try to transfer ur music via iTunes NDE MAKIKILALA NG ITUNES MO yan as a actual ipod, u tansfer music as if ur transfering data to a flashdisk kc thats what it is, JUST a flash disk that can play MP3s, IPODS media priority makes u convert MP3 and other audio formats into AAC, the fake one play ONLY MP3
