How do earbuds deliver deep bass frequencies with such tiny drivers?

Question

Usually when you have a smaller speaker, you sacrifice the low end, but earbuds seem to manage to deliver substantial bass nonetheless. I assume the proximity to the eardrum helps, but I don’t fully understand how.

By the nature of their small design, earbuds do not have subwoofers to push large amounts of bass frequencies. Rather, they sound bassy due to their proximity to the ear, the enclosure they make with the ear, and via the natural resonances of bone conduction.
