How does Bluetooth work?

Ever wonder how your earbuds talk to your phone without wires?

Think of Bluetooth like two walkie-talkies doing a secret handshake.

First, they use short-range radio waves—just a few feet—to say "hello."

Then they do a quick pairing handshake, like a secret code, so they know it's each other.

Each device has a unique ID so they don't get mixed up with other gadgets nearby.

Bluetooth uses very little power, so your earbuds don't run out of battery fast.

And if there's noise from other devices, it hops channels—like changing lanes—to keep the connection clear.

That's Bluetooth—tiny radios making big connections.
