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.

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 Bluetooth headphones connect to a smartphone?

Most wireless headphones use Bluetooth to communicate with the device, and in some cases, there may be a problem with the connection between the mobile app and the headphones.
If you are using wireless headphones with your mobile device, make sure your mobile device OS and headphone app are up to date.

Earphone-type wireless headphones are more susceptible to connection issues, such as broken connections, out-of-sync, and dropped calls than other wireless headphones due to their form.
In some cases, when communication is lost, your head itself is blocking the signal, which can be challenging to resolve.

Some headphone manufacturers say that updating the firmware may improve synchronization and other issues, but not all headphones.
Nevertheless, there may be solutions on the manufacturer’s website, including firmware updates, so you should check them out.

Of course, you need to keep your firmware up to date.

Pair with Mac (macOS) PC

  • step 1 Apple menu select [System Preferences] from the [ ] menu on the computer
  • Step 2 Select [Bluetooth]
  • Step 3 Set the headphones to the device registration mode (pairing mode).

Check that the main unit lamp blinks blue and red alternately, or that blue blinks twice consecutively.

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 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.
