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.

Sound is based off of SPL (vibrations). The volume of the space inside your ear is tiny. Proportionally the driver is huge to that volume. You can read some about it in the IEC 60942 to learn more about sound level calibrators (drivers) or IEC 61672-1 which is about sound level meters. So the receiving end of it. You can pirate them if you want.
