Basic information on Bluetooth pairing and Bluetooth connection

  1. Bluetooth headphones and speakers can’t connect to multiple devices at a time.
  2. Just think of how making multiple phone calls to multiple devices at once is not possible: If your headphones are already connected to one mobile device, they cannot be simultaneously connected to another mobile device.
  3. To tackle this, operate the mobile device that was first connected, and cancel the Bluetooth connection with the headphones or speaker. You can then connect to another mobile device. Read the explanation of Bluetooth pairing and Bluetooth connection below.


What's Bluetooth pairing?

Bluetooth pairing is a form of information registration for linking devices. By registering device information (pairing) between devices, they can connect to one another. In order to use a Bluetooth device, you must first pair it with another Bluetooth device. Pairing is a bit like exchanging phone numbers. Similar to how you must exchange phone numbers with a person you want to call, connecting Bluetooth devices requires you to first pair them to register the pairing information of each device. After pairing the devices the first time, there is no need to repeat this pairing process again. That is because each device has saved the necessary information and can therefore easily connect


In addition, similar to how forgetting someone's phone number means that you cannot call him or her if the pairing information stored by your Bluetooth device is deleted (e.g. device reset), you will be unable to connect it to the device you previously registered.

Should that happen, you will have to pair them again in order for them to be able to connect to each other. In the same way, when you change your mobile device (e.g. when you buy a new smartphone), you must pair the new device and the headphone or speaker again.

Refer to the following pages for the pairing procedures for Bluetooth devices.

NOTE: There is a limited amount of Bluetooth devices that can be registered to the Bluetooth headphones. If you have reached the maximum registration limit and you attempt to register a new device, pairing information of one of the devices you previously registered (the earliest device in your connection history) will be deleted.

Bluetooth connection

A Bluetooth connection is a transmission between two Bluetooth devices. In order to complete the Bluetooth connection, you must first register the information of each device with the other. After pairing the devices the first time, there is no need to repeat the pairing process to connect again.

Establishing a connection between two Bluetooth devices is like making a phone call. Similar to how you can call someone if you both know one another's phone number; two devices can connect if they have been paired, thereby storing one another's pairing information.


The connection and disconnection procedures for Bluetooth devices differ depending on the product.
