There are several potential dangers.
Loss of hearing - that's due to user irresponsibility, not the manufacturer
A danger not often thought about is that when the iPod was more expensive than it is today, people would get mugged for them. It would be the trademark white earbuds that gave away what a person was listening to, making them easy targets.
Yet another possibility is any electronic device, including the iPod, that uses a lithium-ion battery. There was a period not long ago where there was some shoddy manufacturing done overseas involving impurities in the lithium liquid where there were some metal lithium shards contained within the battery. If the shards make contact, they can spark, causing the famous "exploding iPod/exploding laptop/exploding cell phone" you might have heard about in the news. But the odds of it are practically nil, which is why when it happens, it makes the news.
Another danger is that when you wear an iPod, you're totally unaware of your surroundings. This can be very dangerous.
