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. Watch the video from Branch Education for more info:

We’ll dive even deeper into Audio sampling rates, and audio bit depth. Finally, we’ll give a brief overview of audio file formats. The key components that produce sound inside Bluetooth headphones are the same as wired headphones. These include magnets, voice coil, and diaphragm.


Bluetooth headphones, unlike wired headphones, require batteries to function.The Bluetooth hardware module is a component that makes Bluetooth communication possible.A Bluetooth hardware module contains two parts: a radio device and a digital controller. The optical range of average wireless Bluetooth headphones is around 20m to 100m./read more: Branch Education
