5. Setup
5.1 Connecting to PC/Xbox
The ONIKUMA X31 headset connects via a wired USB connection. For devices requiring separate audio and microphone jacks, use the included splitter cable.
- For PC (USB Audio): Plug the USB connector directly into an available USB port on your computer. The system should automatically detect and install the necessary drivers.
- For PC (3.5mm Audio/Mic with Splitter): If your PC has separate 3.5mm ports for audio and microphone, connect the headset's 3.5mm jack to the included splitter cable. Then, plug the green connector of the splitter into your PC's audio output jack and the red connector into the microphone input jack. The USB connector is for RGB lighting power.
- For Xbox: Connect the 3.5mm jack of the headset into the 3.5mm port on your Xbox controller. The USB connector is for RGB lighting power and may require a separate USB power source or adapter if the controller port does not provide sufficient power.
5.2 Adjusting the Headset
- Adjust the headband to fit comfortably over your head.
- Position the earcups so they fully cover your ears, ensuring a snug fit for optimal sound isolation and comfort.
- Bend and rotate the microphone boom to bring the microphone close to your mouth for clear voice pickup.
6. Operating Instructions
6.1 Volume Control
The headset features an integrated volume control wheel on the cable. Rotate the wheel up to increase volume and down to decrease volume.
6.2 Microphone Usage
An integrated switch on the cable allows you to mute or unmute the microphone. Ensure the microphone is unmuted for voice communication. Adjust the microphone's position for optimal clarity.
6.3 RGB Lighting
The RGB lighting on the earcups will illuminate automatically when the USB connector is powered. There are no user-adjustable controls for the lighting patterns; they are dynamic gradient lights.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the headset. Do not use abrasive cleaners or solvents.
- Storage: Store the headset in a cool, dry place when not in use. Avoid placing heavy objects on it.
- Cable Care: Do not pull on the cable forcefully or wrap it too tightly, as this can damage the internal wires.
