How Bluetooth Actually Works

Your headphones connect to your phone with zero cables and zero internet — but how does that actually happen? What's really being sent through the air between two Bluetooth devices? In this video, we break down how Bluetooth uses short-range radio waves to pair devices, why it works completely differently from Wi-Fi despite feeling similar, how two devices "agree" to connect securely, and why Bluetooth range is so much shorter than Wi-Fi on purpose. This is the third video in Everyday Explained - a series breaking down the everyday technology you use but never really understood. Check out the first two if you missed how Wi-Fi and GPS work.
