- For PCs/Laptops with a single combined 3.5mm audio/mic jack: Plug the headset's single 3.5mm jack directly into the combined port.
- For RGB Lighting: Plug the USB connector into an available USB port on your PC/Laptop. The USB connection is solely for powering the RGB lights.

- Xbox One/Xbox One S/Xbox One X: Plug the headset's single 3.5mm jack directly into the controller's 3.5mm port. Note: An official Microsoft Adapter (not included) may be required for older Xbox One controllers without a 3.5mm port.
- Nintendo Switch/New 3DS/3DS/3DS XL: Plug the headset's single 3.5mm jack directly into the console's 3.5mm port.
- For RGB Lighting: If your console or a nearby power source has a USB port, you can plug in the headset's USB connector to power the RGB lights.

5. Operating Instructions
5.1 Microphone Usage
- The microphone is flexible and can be rotated 360 degrees to adjust its position for optimal voice pickup.
- Ensure the microphone is positioned close to your mouth for clear communication.
- The headset features a noise-reduction microphone to minimize ambient sound.
5.2 Inline Control
The headset features an inline control unit on the cable for convenient adjustments:
- Volume Wheel: Rotate the wheel to increase or decrease the audio volume.
- Microphone Switch: Use the switch to quickly mute or unmute your microphone.
5.3 RGB Lighting
The RGB lighting effect on the earcups is powered via the USB connection. Simply plug the USB cable into a powered USB port to activate the lights. The lighting is purely aesthetic and does not affect audio functionality.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the headset. For earcups, a slightly damp cloth can be used, but ensure no moisture enters the speaker grilles.
- Storage: Store the headset in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid sharp bends or excessive pulling on the cables to prevent damage.
- Avoid Liquids: Do not expose the headset to water or other liquids.
7. Troubleshooting
7.1 No Sound from Headset
- Ensure the 3.5mm audio jack is fully plugged into the correct port on your device.
- Check the inline volume wheel on the headset cable and ensure it is turned up.
- Verify your device's audio output settings and volume levels.
- If using a PC, ensure the correct audio output device (e.g., 'Headphones (ONIKUMA K8)') is selected in your sound settings.
7.2 Microphone Not Working
- Check the microphone mute switch on the inline control unit and ensure it is in the 'unmute' position.
- Ensure the 3.5mm audio jack is fully plugged in. If using a PC with a splitter, ensure the pink microphone jack is correctly connected.
- Verify your device's microphone input settings and ensure the correct input device is selected.
- For consoles, check the microphone settings within the console's system or game settings.
7.3 RGB Lights Not Working
- Ensure the USB connector is securely plugged into a powered USB port.
- Try plugging the USB into a different USB port or device to rule out a port issue.
7.4 Compatibility Issues with Xbox One
- If your Xbox One controller does not have a 3.5mm audio jack, you will need a Microsoft Stereo Headset Adapter (sold separately) to use the headset.
8. User Tips
- Wired Connection Clarity: The K8 headset is wired. For PC users, remember to use the included Y-splitter cable if your computer has separate audio and microphone ports. For consoles and mobile devices, the single 3.5mm jack is typically sufficient.
- Microphone Positioning: Take advantage of the 360° rotating microphone and its noise reduction feature by positioning it optimally for your voice, ensuring clear communication with teammates.
- Comfort for Long Sessions: The soft memory protein earmuffs and adjustable headband are designed for extended wear. Adjust the headband to fit comfortably to prevent fatigue during long gaming sessions.
