Mr. PSVR-2
One of the features that the Quest 2, Quest 3, Quest 3S, and Quest Pro have is the ability to accessorize, helping to take your VR gaming to the next level. Whether that is for the comfort or audio aspects, there is usually something you can find that will help. Ever since using the Quest 2 and now the Quest 3, KIWI design has always had something that would satisfy that thirst. I have tried their different head straps and even their grips, which have been fantastic to use. But now with the Quest 3s that came out in October of 2024 and the newly released Quest 3s Xbox Edition, there has been something that many others, including myself, have been wanting: a headset with a battery and audio combined. Let’s take a closer look at the KIWI design K4 Duo AIO Audio Head Strap with Battery for the Quest 3/3s.
Features:
- 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.
- Ergonomic 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.
- Built to Last. Safe for Everyday 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.
In looking at the box, you have what KIWI design is known for, and that is simply making things better. The simplicity and presence of the K4 Duo are represented right on the box. I do like how the light shines on certain parts, almost giving off a Batman vibe.
Inside, you will find the K4 Duo, the user manual, and the warranty guide. Again, simple is what you can expect here and from KIWWI design.
On the side, there is the rear head cushion to make sure you have that sweet comfort spot for your head. We also have the attached USB-C cable that will plug into your Quest 3/3s and the attached 40mm on-ear headphones that can fold down and shift with you, as well as having the ability to move the earphones up and down to have them fit what’s best for you. This means if you want to lie down, groove about, or game your way, you will have the comfort and sound to go with it.
On the rear of the K4 Duo, you have the Stealth Knob to make sure everything is as secure as you would like. Also, notice the 4 dots that are lit when the 5,300 mAh battery is charged. This gives you an extra 2-3 hours of VR time to enjoy.
With the attached cable plugged into your headset, you will see how the K4 Duo is charging your Quest 3/3s headset.
But now you might wonder how the KIWI design K4 Duo AIO Audio Head Strap with Battery feels and sounds. I can say that the way everything feels balanced on my head is very comfortable, thanks to the adjustable cushioned top strap that goes on the top of my head and the rear head washable cushion. It feels very lightweight, almost like a pillow on the top and back of my head, and being able to not have to have another pair of headphones on top of my head or in my ear while playing and wondering the next time one of them would either fall out or off is truly fantastic and one less thing to have to worry about. Plus, that balanced sound with the right amount of bass of the on-ear headphones adds to the experience of my virtual reality time. The K4 Duo supports DualFast Power Charging (as long as you have a PD 45W charger), where you can charge both your Quest 3/3s headset and the K4 Duo in about 2.5 hours, which is pretty amazing.
My final thoughts are as simple as KIWI design makes them. When looking at your Quest headset, whether it is the Quest 3, which includes an audio jack, or the Quest 3s, which does not have an audio jack, and knowing how, when you first put on the Quest headset out of the box, there is that feeling that things could be better, from comfort to the sound. The KIWI design K4 Duo AIO Audio Head Strap with Battery checks all the boxes for both headsets. You have the comfort, the audio, and the battery power to give your VR gaming the overdrive it needs.
The KIWI design K4 Duo AIO Audio Head Strap with Battery is out now, and you can order yours now by visiting the KIWI design site (use code MRPSVR) or you can order on Amazon.
