It is essential to consider the structure as a whole:

The Bluetooth earbuds come in a connected design. Earbuds don't directly connect to the phone, but a small cord links the earphones together instead. Each end of the connection is made up of a component. In the first place, this keeps the rechargeable batteries in place, allowing for somewhat better battery life than Bluetooth headphones would have.

You're dealing with a vast number of components, although they're all so tiny.
