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.

Even if you have good quality earbud you have to create a good seal to your ear opening or those lower frequencies are greatly reduced.
