ELI5 Why, in an airplane that cost millions of $, the mic of the pilot sounds like a 5$ mic ?

The mic is fine. If you've ever been on a plane with a built-in entertainment system and heard an announcement over your headphones, it was probably perfectly audible. 

The issue is projecting the sound that mic captures into the cabin. It's not trivial to equip a large space for sound, especially when you're fighting all the vibrations and white noise produced by the engines.
