How to pair INZONE Buds gaming headset using Bluetooth or USB transceiver

• Only Bluetooth devices that support LE Audio ^* (sound communication standard for Bluetooth technology) can be used. If your Bluetooth device does not support LE Audio, connect the supplied USB transceiver. For the latest information on the compatible devices, refer to the support website.
• Place your device within one meter of the Android smartphone / device.
• The headset is charged sufficiently.
• The operating instructions for the Android smartphone is at hand.
• If pairing is not established within 5 minutes, pairing mode is canceled. In this case, start the operation again from the beginning of 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 6th device is paired
    The headset can be paired with up to 5 devices. If a new device is paired after 5 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 connected Bluetooth device
  • When the headset is initialized
    All of the pairing information will be deleted. In this case, remove the headset pairing information from the connected device and pair it again.
• The headset can be paired with multiple devices, but can only play music from 1 paired device at a time.
• If there is no pairing history between the headset and the Bluetooth connected device, even when you try to change the mode on the headset, it is not possible to switch from the Bluetooth connection to the USB transceiver connection.
• If the last connected Bluetooth device is placed near the headset, the headset may automatically connect to the device when you turn on the headset and may not connect to another device.
  If this occurs, cancel the connection on the last connected Bluetooth device or turn off the Bluetooth function on that device.
• Update your Bluetooth audio device to the latest firmware. If you're looking for the firmware of your bluetooth audio device, please go to the Firmware & Software section of your model support page. If there is no firmware update under the Firmware & Software section, it just means that Sony is currently not offering a newer firmware.

Step 3. Connect the USB transceiver to a USB port of the computer, PS5, or USB Type-C compatible smartphone.

Note:

• Connect the USB transceiver directly to the computer, PS5, or USB Type-C compatible smartphone, and not via a USB hub.
• When connecting the USB transceiver to a computer, connect it to the USB Type-C port on the computer without using a USB Type-A conversion adaptor.

1. If the device does not recognize the headset microphone, make sure the slide switch of the USB transceiver is set correctly.
2. If the headset cannot connect to a computer, PS5, or USB Type-C compatible smartphone via a wireless 2.4 GHz connection, press and hold the connect button on the USB transceiver for about 5 seconds or more to pair.
3. Press the connect button with an object with a thin tip that will not break, like a paperclip.
4. During a call, there may be noise in the voice that the other party hears. Connecting the USB transceiver to a different USB port may improve the situation.
