First, let’s start with “What is Bluetooth?”

Bluetooth is a wireless communication standard. Compatible devices can exchange data without connecting cables. The valid range is about 10m. Because it is an international standard, any compatible device can be connected by any manufacturer in each country.

Bluetooth mark
A person who says, “I can’t get right to the point …” may be more natural to understand if you listen to the examples. For example, imagine a Bluetooth earphone.

Until now, earphones were designed to insert the end of a cable into a smartphone or PC. However, if you connect a Bluetooth-compatible headset to your smartphone, you don’t need a rope. To wirelessly transmit music data from smartphones to earphones, Bluetooth earphones can also be used in independent shapes like earplugs.

How to pair Bluetooth headphones (Android / iOS)

  • step 1 Put the headphones in device registration mode (pairing mode)

Hold down the “power” button or “PAIRING” button on the headphones until the lamp on the central unit blinks (about 7 seconds).
There are the following two patterns for the lamp blinking.

The blue lamp blinks twice each time
Blue and red lights flash alternately
Refer to the instruction manual as it varies depending on the model.

  • Step 2 Turn on the Bluetooth of the smartphone or tablet you want to connect

For Android
Select [Settings]-[Wireless & Networks]-[Bluetooth].
For iOS
Select [Settings]-[Bluetooth]

  • Step 3 Touch the displayed headphone model name on the smartphone or tablet screen.

* 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.

The pairing is completed.

Procedure to connect Bluetooth earphone with Windows PC

1. Start pairing
First, operate the buttons on the Bluetooth earphone side to start matching.

The operation method differs depending on the earphone or speaker, so check the manual.

* Playing and stopping, power and volume are nothing, but you may start pairing by pressing and holding a relevant button.

2. Add device
Open “Devices and Printers” in Control Panel, and click “Add Device.”

Many people drop out without finding this. Now, click on this to start searching for devices.

When the Bluetooth earphone is detected automatically, the device installation will begin.

Windows now recognize the Bluetooth earphone as a playback device.

3. Priority output for Bluetooth earphones
However, with this alone, you will not be able to hear the sound from the Bluetooth earphone. As before, you will get out of the speaker.

This is because the speaker you have been using has priority over Bluetooth as the output destination.

Go to “Control Panel”-> “Sound,” right-click the icon that says “Bluetooth Audio Device,” and try “Set as Default Device.”

About behavior
With this setting, the sound of the Windows PC will be played from the Bluetooth earphone, but no sound will be output from the speaker.

Here, when you turn off the Bluetooth earphone, it automatically switches to output from the speaker.

Also, when you turn on the Bluetooth earphone again, the output to the Bluetooth earphone has priority still, and the sound output from the speaker stops.
