This dude is running so fast that he’s at the same pace as sound, if he turns on his mp3, can he hear music?

Okay so there’s this guy running really really fast. Same speed as how sound travels. It’s through normal air, not vacuum. If, by chance and golly it could happen, he turns on his mp3, can he hear his music from it? And why?

He could only hear it if he held the speakers in front of him or else he would out run the sound waves…. but even if he did hold it out it would be so Doppler shifted he might not understand the music

yes,he can hear to his mp3 player.

because,when boy is running at any speed his mp3 player will be at same speed.so,the relative distance or velocity is zero.they are both at same distance.
