I think, maybe. first off, no one can run at the speed of sound so that is unrhetorical and second if someone did I'm sure they would hear the iPod because he's running as fast as the sound of it. but that's just a random guess.
Yes he will, because the the ipod is moving along with the jogger, so the sound produced in the headphones will reach the jogger's ears, immaterial of the speed with which he's jogging . But he will not hear sound produced by a stationary sound source.
Oh, okay. Thank you guys!
Yes, this is a serious question, and the answer is no, a jogger cannot hear his iPod if he runs at the speed of sound. This is because as an object (in this case, the jogger) approaches the speed of sound, the air particles around it are compressed, creating a buildup of pressure. At the speed of sound, this pressure buildup causes a sonic boom, which is basically a shock wave of sound. The jogger would be moving at the same speed as the sound waves he is producing. Therefore, he would never be able to catch up to those sound waves in order to hear them. In other words, the sound waves from his iPod would be left behind him, unable to reach his ears due to the speed at which he is moving.
