Answer 1

So traditional earpieces work with wires. Information (such as music) is sent through the wire as an electric signal. This signal is understood by the earpiece and it makes the speaker inside the earpiece vibrate in tune with the music, which means you hear the music. Bluetooth earpieces work almost the same, except instead of wires they use Bluetooth. Bluetooth is a super old and yet still highly used method of sending data without wires. Think of it like sending data through a mobile phone network, except it goes from your phone and to the earpiece in this case. The data is sent to the earpiece in a similar way to how it is sent through electricity, and the processor inside the earpiece can understand that data and can translate it to electrical signals for the speaker.
