- Extended Playtime with Enhanced Battery: Use the KIWI design battery pack to extend your gameplay time by a maximum of 3 hours. Designed for optimal performance and customized to meet your demands, you can play for longer without worrying about the battery running out. Please note that the environment and manner of use have an impact on battery life. Long-term high-power applications should be avoided.

- Tighten the Head Strap for a Secure Fit: The front and back of the head strap are balanced by the lightweight battery pack, which significantly lessens the weight on your head. To properly fit the virtual reality headset to your head and play games without worrying about discomfort, merely crank the rear knob or pull the adjustment VR accessories.
- Comfortable and Balanced Design: A balanced weight design eases strain on your head and neck, while the thicker cushioning and bigger back support lessen facial pressure. To provide a more comfortable fit, adjust the wearing angle up or down until it strikes the ideal balance between front and back weight.
- Safe and Reliable VR Headband: Various safety measures, including NTC and UL credentials, and high-quality components were used in its construction. With its 52-degree damping hinge and quick-adjust knobs, it's comfortable to wear and share with loved ones.
