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.

Earbuds have to send out a lot less sound compared to speaker as they sorta seal your ear and are much closer so the inverse square law applies less
