Setup
Connecting to Devices
The NUBWO U3 headset connects via a standard 3.5mm audio jack, ensuring broad compatibility:
- Gaming Consoles (PS4, PS5, Xbox, Nintendo Switch): Plug the 3.5mm jack directly into the controller's audio port. For older Xbox One controllers without a 3.5mm port, a separate adapter (not included) is required.
- PCs/Laptops: If your PC has a single combined audio jack, plug the headset directly. If your PC has separate audio (headphone) and microphone jacks, use the included adapter cable to split the connection.
- Tablets/Smartphones: Plug the 3.5mm jack directly into the device's audio port.

The NUBWO U3 headset offers broad compatibility with gaming consoles, PCs, and mobile devices via its 3.5mm jack.
Operating Instructions
Volume Control
Adjust the listening volume using the inline control wheel located on the headset cable. Rotate the wheel up to increase volume and down to decrease it.

The inline control unit on the headset cable allows for easy volume adjustment and microphone muting.
Microphone Usage
The flexible, noise-canceling microphone can be positioned for optimal voice pickup. To mute the microphone, slide the switch on the inline control unit to the 'Mute' position. Slide it back to 'Unmute' to enable communication.

The NUBWO U3 features an ultra-clear microphone for effective communication during gaming or online calls.
Adjusting the Headset
The headset features an adjustable headband to fit various head sizes comfortably. Gently slide the earcups up or down along the headband to achieve a secure yet comfortable fit. The memory-protein ear cushions are designed for extended wear without discomfort.

The adjustable headband ensures a comfortable fit for both children and adults.
Maintenance
To ensure the longevity of your NUBWO U3 headset, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe down the earcups and headband. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the headset in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: The reinforced nylon braided cord is designed for durability, but avoid excessive pulling, twisting, or bending to prevent internal damage.
- Microphone: Keep the microphone clean and free from dust. Avoid bending it excessively.

If you encounter issues with your NUBWO U3 headset, try the following solutions:
