About this item
- All-in-One Audio Head Strap with Battery: The K4 Duo Headset revolutionizes your VR experience by combining premium audio and charging into a single, streamlined solution. Unlike other accessories that require multiple cables, our patented single-cable design delivers both power and crystal-clear sound simultaneously.
- High-Quality Sound, Immersive Experience: The K4 Duo AIO is equipped with dual 40mm dynamic drivers, delivering balanced sound and deep bass to enhance your immersion. Instantly toggle between deeply immersive headphones and the headset's built-in speakers with just one button press. Perfect for when you need to quickly hear your surroundings or share audio with friends.
- DualFast 45W Charging: Powered by dual PD chips, our advanced charging system juices up both your headset and K4 Duo at maximum speed through just one USB-C connection. With 45W max input power, you can achieve a full charge in just 2.5 hours—that's 30% faster than standard charging solutions. Never miss a moment in VR due to a low battery again.
- Engineered for Perfect Balance & Comfort: K4 Duo Audio Head Strap achieves a near-perfect weight distribution with your Quest 3/3S. The strategically positioned headphones act as a counterweight, making rapid head movements feel more stable and natural during intense gameplay. 3-degree-of-freedom adjustable headphones provide a customized fit for every head shape and size.
- Safe and Durable, Reliable Use: The K4 Duo AIO is built with high-quality battery cells, certified by NTC and UL, and rigorously tested in TUV laboratories, ensuring product safety and reliability, so you can enjoy your VR experience with peace of mind.
