Your ears “pop” due to the relief of a pressure differential across your eardrum, from your outer ear to the middle ear.

Your middle ear is connected to the space behind your nose and throat by something called the *Eustachian tube*, and actions like swallowing or chewing causes it to open up, allowing air pressure to equalize.
