Pairing and connecting with a Bluetooth device
The operation to register the device that you wish to connect to is called “pairing”. First, pair a device to use it with the headset for the first time.
Before starting the operation, make sure of the following:
- The Bluetooth device is placed within 1 m (3 feet) of the headset.
- The headset is charged sufficiently.
- The operating instructions of the Bluetooth device is in hand.
-
Enter pairing mode on this headset.
Turn on the headset when you pair the headset with a device for the first time after you bought it or after you initialized the headset (the headset has no pairing information). The headset enters pairing mode automatically. In this case, proceed to step 2.
When you pair a second or subsequent device (the headset has pairing information for other devices), press and hold the
(power) button for about 7 seconds. 
Check that the indicator (blue) repeatedly flashes twice in a row. You will hear the voice guidance say, “Bluetooth pairing”.
-
Perform the pairing procedure on the Bluetooth device to search for this headset.
[WH-1000XM4] will be displayed on the list of detected devices on the screen of the Bluetooth device.
If [WH-1000XM4] and [LE_WH-1000XM4] are displayed, select [WH-1000XM4].
[LE_WH-1000XM4] will be displayed first, but wait until [WH-1000XM4] is displayed.
It may take about 30 seconds to 1 minute for [WH-1000XM4] to be displayed.
If [WH-1000XM4] is not displayed, try again from step 1.
-
Select [WH-1000XM4] displayed on the screen of the Bluetooth device for pairing.
If Passkey (*) input is required, input “0000”.
*A Passkey may be called “Passcode”, “PIN code”, “PIN number”, or “Password”.
-
Make the Bluetooth connection from the Bluetooth device.
Some devices automatically connect with the headset when the pairing is complete. You will hear the voice guidance say, “Bluetooth connected”.
Hint
- The operation above is an example. For more details, refer to the operating instructions supplied with the Bluetooth device.
- To delete all Bluetooth pairing information, see “Initializing the headset to restore factory settings”.
Note
- If pairing is not established within 5 minutes, pairing mode is canceled. In this case, start the operation again from step 1.
- Once Bluetooth devices are paired, there is no need to pair them again, except in the following cases:
- Pairing information has been deleted after repair, etc.
- When a 9th device is paired.
The headset can be paired with up to 8 devices. If a new device is paired after 8 devices are already paired, the registration information of the paired device with the oldest connection date is overwritten with the information for the new device. - When the pairing information for the headset has been deleted from the Bluetooth device.
- When the headset is initialized.
All of the pairing information is deleted. In this case, delete the pairing information for the headset from the device and then pair them again.
- The headset can be paired with multiple devices, but can only play music from 1 paired device at a time.
