Headphone Design

Acoustic Principle
The basic design of the headphones. There are 3 different types: Open: Have ports that allow air through the back of the diaphragms, enabling the headphones to sound like the music is coming from an outside source. Closed: Completely sealed and have no air passing through the diaphragms. Sounds like you are in a closed off room. Semi-open: Have slots or ports in the back of the cup and are partially open. This allows for a mixed sound between an open and closed headphone.
