With the battery dangling to one side, we keep digging. This clear plastic brace kept the driver in place, until we pulled on it too hard.

Next, the star of this 'Pod—the (relatively) large driver, which lifts out to give us a peek at the microphone that listens to the inside of your ear.

Apple uses this mic to actively adjust the levels of whatever you're listening to (like in the HomePod), and to determine whether or not your tips are fitting correctly.

This driver might be called the driver, but the one actually doing the real driving is the voice coil.

In principle, these work like any other speaker. Current creates an electromagnetic field in the coil, which moves the speaker cone to pump those sick beats into your ears. It also creates the "anti-noise" to cancel out any anti-sick ambient noise.
