ELI5: How do Bluetooth things work, more specifically Bluetooth earphones?
gpt
Wireless devices (basically everything, these days) communicate by sending electromagnetic waves over the air that get picked up by other devices and interpreted as data. But in order for two devices to talk, they need to be speaking the same language, like maybe the waves should all be a certain length. Bluetooth is simply a standard, or a set of guidelines, for what type of waves two devices should use to communicate. If your device follows the Bluetooth wave rules, your device can talk to other devices that follow the Bluetooth wave rules.
