So how are Bluetooth and Wi-Fi different?

The first is the familiar Wi-Fi, which is good at connecting multiple devices simultaneously. It has been created as a hub that connects to the Internet. The communication speed is breakneck, and it is good at mass data communication. However, because of its considerable power consumption, it is used for stationary devices such as routers that can supply power from outlets.

Bluetooth, on the other hand, is a technology designed for one-to-one communication. Both communication speed and communication distance are weaker than Wi-Fi, but they consume less power and can be used for long-term devices such as keyboards and mice. Since these devices have a small amount of data to be communicated at one time, data delay is unlikely to occur.

How to set up pairing using iPhone

1. First, launch the iPhone settings screen and tap “Bluetooth.”
2. When Bluetooth is turned on, it will detect nearby devices, so tap it.
3. Tap the device, and if “Connected” is displayed, pairing is complete.

How to set up pairing using an Android smartphone

1. Launch the Settings screen and tap “Bluetooth.”
2. Turn on Bluetooth to detect nearby devices.
3. Since pairing is required, tap “OK” to complete the setting.

The setting method varies slightly depending on the terminal and OS version, but if you turn on Bluetooth, it will automatically detect nearby devices. The procedure is not complicated, so check it on your device.

  • step 1 Apple menu select [System Preferences] from the [ ] menu on the computer

There are the following two patterns for the lamp blinking.

  • Step 4 Select the [Connect] button to the right of [〇〇 (headphone model name)] displayed in the [Device] field.

* If you are asked for a passkey, enter “0000 (Zero Zero Zero Zero)”.
A passkey is sometimes called a passcode, PIN code, PIN, password, etc.

  • Step 5 Confirm that “Connected” is displayed under the headphone model name.

This completes the pairing process with the headphones.
