Because when you cover your ears with earbuds, the sound waves
travelling through your scull and into the ear canals can not escape
there but will be reflected back, thus you hear the sound louder.

> How does the sound of my scratching my scalp get into the earbuds?

Bone conduction followed by reflection in your ear canals.
