Don't use iPod in a thunderstorm

In a report on a man struck by lightning while jogging and using an iPod, the report concludes that even though the iPod did not attract the lightning, once struck, he suffered far greater harm to his body due to wearing the iPod. Refer this report:

His eardrums were ruptured, his jaw fractured and he suffered first- and second-degree burns from his chest — where the device was strapped — up into his ear channels, along the trail of the iPod's earphones. He also had burns down his left leg and foot, where the electricity exited his body, blowing his sneaker to smithereens in the process.
Heffernan said in an interview with the Canadian Press that the man's experience ought to be a cautionary tale for anyone wearing earphones outdoors during a thunderstorm. "Using things like this, a mobile phone or an iPod, there isn't actually an increased risk (of incurring a lightning injury)," he said from Vancouver. "But we just suggest that if you are unlucky enough to be hit by lightning while listening to anything with earphones, you may be more likely to do yourself some damage."
"But once electricity contacts the iPod, then the metal will conduct the electricity and can cause secondary burns, as this gentleman had to his chest underneath where the iPod was and up where the wires went up into his ears, and possibly even cause enough muscle contraction that either caused the jaw fracture or perhaps he fell forward onto his jaw."

Sp, even though the iPod did not cause the electricity to hit him, once he got hit, it amplified the damage and caused him some permanent damage. So this is more of a precaution to not use devices such as iPod's and mobile phones in a thunderstorm or when there is a higher chance of electricity hits.
