That is probably the problem. Get a flashlight and check the headphone jack on the nano and make sure there is not lint, etc. impeding inserting the headphone jack. If there is not reinsert your headset jack firmly (the jack on the Nano is very tight when it is new) and make sure it is pushed all the way in. There should be no gap between the plastic on the headset jack and the body of the nano.
