Headphones come in different shapes and sizes, but there are a few common words you should know. Let's start by looking at types of headphones.

In Ears
Properly known as supra-aural headphones, on-ears sit on your ears so there's some sound leakage, but they're more portable and smaller than around-ear headphones.
On Ears
Circum-aural headphones are the bulkiest type of headphones, but they provide a comfortable fit and very little audio leakage, and have more space for larger drivers too.
Around Ears
These come in two types: closed or open back. The open back reduces echoes and delivers a wider soundstage, but this, leaks more sound, and can disturb others.
Closed/ Open back
Drivers are where the sound comes from, and that's just like a speaker, but smaller. The most common types are dynamic drivers, and this is what they look like on the inside.
What's a driver?
There are three components, a diaphragm (which moves and makes the sound) a magnet, and a coil, which draws power to move the diaphragm.
Magnet, coil, diaphragm
When the coil is powered, it forms an electromagnet. This is repulsed by the magnet, making the diaphragm move, thousands of times a second — and now you know the basics of how your headphones make sound.
