Q: can't hear music on my nano

Hi clive186,

There are a few things that you can try, like making sure that your headphones are fully plugged and make sure you fell them click in as well as checking the settings to make sure that nothing is set to low. You can also restore your iPod nano and sync the music again to test. Take a look at the article below for more information.
