Basic information of Bluetooth pairing and
Bluetooth connection.
IMPORTANT:
Bluetooth headphones and speakers can’t connect with multiple devices at a time. 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 with another mobile device. 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.

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 create a new pairing between the new device and the headphone or
speaker.
Refer to the following pages for the pairing procedures for Bluetooth devices.
How to pair Bluetooth headphones with a source device.
How to pair a Bluetooth speaker with a source device.

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, the 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 pairing 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. For details, refer to your product's instruction manual or help guide.
If you cannot pair or connect your Bluetooth product, refer to the following page.
Bluetooth connection with wireless
headphones or speakers is suddenly
disconnected.

The headphones or speakers may have automatically switched the Bluetooth connection to
another paired device. On that other possibly connected device, disconnect the Bluetooth
connection and then try connecting with the desired device again.
NOTES:
The wireless headphones or speakers can be paired with multiple devices, but cannot connect to
two or more devices at the same time.
The operation described in this FAQ is not guaranteed to resolve the issue.
If the issue occurs, the following Suggestions may also be helpful:
Suggestion 1
Even if the connection is completed, the Bluetooth headphones or speakers connection may be
switched to a previously paired device for which a connection request was issued later.
NOTE: The following example shows the situation when the Bluetooth connection with
headphones and smartphone are disconnected.
1. Headphones and smartphone are connected via Bluetooth
2. Computer (previously connected with the headphone) tries again to connect the headphones
via Bluetooth
NOTE: Depending on the device, such as computer, a connection request may be issued
automatically. For details, see the Suggestion 2.

3. The Bluetooth connection with the headphones and smartphone are disconnected, and the
headphones are connected with the computer
Suggestion 2
Depending on the device, the connection request to the last connected device may be switched
when the device is turned ON or the Bluetooth setting is ON.
NOTE: The following example shows the situation when the computer is connected to the
headphones automatically.
1. The computer turns ON
2. The computer requests to connect with the headphones

3. The computer is connected to the headphones via Bluetooth
Suggestion 3
When the situation described in Suggestion 1 and Suggestion 2 occur, the wireless headphones
or speakers may be connect to an undesired device. To prevent this, initialize the headphones or
speakers (see the product manual), or delete the paring information of the headphones or
speakers on the device that you do not want to connect (see the manual of that device).
Sound or Bluetooth connection cuts or noise
occurs from the headphones or speakers.
Various reasons can cause interference to the sound or Bluetooth connection of the wireless
headphones or speakers. Please check the following solutions for each cause:

1
Using the Bluetooth device close to Wi-Fi routers,
personal computers, microwave ovens, refrigerators,
etc.
Wi-Fi routers, personal computers, microwave ovens,
refrigerators, etc. are devices that emit radio waves.
Bluetooth devices may be affected by these radio waves
when using them in a location with a mixture of multiple
radio waves.
Please use the Bluetooth device
away from Wi-Fi routers, personal
computers, microwave ovens,
refrigerators, etc. in order to avoid
radio wave interference.
If you use a headphone set with a
noise canceling function, turn the
noise canceling function off.

2
Using the Bluetooth device in the pocket of the chest
or pants, or a bag while listening to the audio.
Bluetooth devices can be affected because the human
body blocks the Bluetooth antenna of the Bluetooth
device and creates an obstacle for Bluetooth
transmission.
Move the Bluetooth device to a
position where there is no obstacle,
such as a human body, to
Bluetooth communication when
using the Bluetooth device in a
pocket or a bag.

Using the Bluetooth device close to other Bluetooth
devices.
Bluetooth devices may be affected by these radio waves
when using them in a location with a mixture of multiple
radio waves.
Turn off the Bluetooth function of
the other Bluetooth devices.
C
as
Using the device away from the player, such as in a
different room.
Keep the Bluetooth
headphones or speakers as close to
the Bluetooth player as possible.

Bluetooth communication gradually becomes weaker the
further away Bluetooth headphones/speakers are placed
from a Bluetooth player. When using Bluetooth
headphones or speakers and a Bluetooth player in
different rooms with the doors closed, Bluetooth
communication may be weak.

Playing music (audio data) via the Bluetooth device
placed in a case.
If a protective case uses metal objects or thick materials,
Bluetooth communication can be interfered with by
those objects or materials and the signal can
become weak.
Remove the case of the Bluetooth
player.
C

6
Playing music (audio data) streamed via the Internet.
Sound is affected by the communication condition of the
Internet since music (audio data) that is streamed to a
Bluetooth player is transferred to Bluetooth
headphones or speakers. Also, playing music (audio
data) that has a large volume has more impact on sound.
Play downloaded audio contents,
not stream via the Internet.

Playing music with a large file size or High-
Resolution audio format.
The file size becomes large when music files are
compatible with the High-Resolution audio format.
Music files with a large size may affect Bluetooth
communication.
Change the settings Bluetooth
audio streaming playback quality
of your Bluetooth headphones or
speaker to Priority on stable
connection.

8
Using the Bluetooth function when a lot of
applications are running at the same time.
Quit apps which you are not using
on the device to reduce the load.
If the issue persists, follow these steps:
1. Restart your devices.
2. Reconnect the Bluetooth connection.
3. If the connected device has the Near Field Communication (NFC) function, use it to
reconnect.
4. Reset / initialize your connected device.
NOTES:
For details on how to reset your connected device, refer to the manual supplied with the
product.
If the remaining battery level of your device is low, charge the battery first and then try
the procedure above.
