Issue not resolved

If the issue is still not resolved, please read this information on servicing your iPod.

In particular, if this is a brand new iPod nano, make sure the headphones plug is fully inserted into the iPod's headphones jack. The fit is often tighter than expected, especially when new. It should "click" into place.

I have same problem but my ear phones will only go in so far no matter how hard i push any suggestions ?

If you see a gap between the side of the iPod and plastic part of the headphones plug, it is probably not pushed in all the way. If it won't go in any further, maybe you have some debris inside the headphones jack that is blocking the plug.

If the plug is inserted completely, try another set of headphones to rule out faulty headphones.
