The principle of reduced pressure
Earbuds into the ear,principle is to make the air does not directly into the ear,air through the earplugs holes into the chamber,will adjust the pressure through air chamber.When pressure change,both ends can form resistance,air is not directly into the ear,adjust the air pressure change through the air chamber.Making the eustachian tube function of the ear will not result in a rapidly changing air pressure and cause too great pressure.
