The Engineering Inside Wireless Earbuds || How do Wireless Earbuds and Audio Codecs Work?
Let's take apart these wireless earbuds [Apple AirPods 2] and see all the components. Then we'll explore audio codecs and the world of digital audio, and see how it all works.

This video explores the inner workings of wireless earbuds and specifically, we'll explore these Apple AirPods 2. We'll give you a general overview of how these earbuds work, and then dive into how Audio is represented digitally. We'll dive even deeper into Audio sampling rates, and audio bit depth. Finally, we'll give a brief overview of audio file formats.
