My newly store bought ipod shuffle has no sound
I just bought an ipod shuffle 4th generation today on the 30th June 2012. I managed to sync all my songs(93 songs) into my ipod without the problem. The I decided to fiddle around with it, so i plugged in my sony heeadphones and pressed play. It worked perfectly fine, then I pressed the voiceover button for a while and the sound/music is gone. I tried different headphones and earphones but they all don't work. I tried restoring my ipod but nothing has changed. Please help!
iPod shuffle, Windows 7
