Review: Get this, you won’t regret it. - Get this. I’ll reiterate what the other reviews have stated, it is a game-changer. Literally. Ha! This is one of those items I go back on forth on because it certainly it isn’t anything I need. So I could save the money and I wonder if it will be worth it. If you use your device all the time, it is totally worth it. It fits so much better. And the extra battery life is great for when I want to exercise a bit longer. My neck doesn’t hurt. The back of my head doesn’t hurt. I feel like my head and neck are aligned. If you’re on the fence, get off of it and buy it. As for what folks said about charging, I haven’t had troubles. I honestly don’t understand the issues. I plug it in. It charges. Like anything else. I did get the 45 watt charging block as people recommended, maybe that makes the difference.
Review: A game changer - This is amazing, I bought this a year ago now, and it's amazing, it's a light weight design, it's comfortable, it's got a good battery life, and holds up amazing to playing games and makes it way more comfortable to play, and with the quest 3 lightweight design, having a light weight battery head strap is a game changer, 10 out of 10 would recommend, it's easily adjustable, it took like 2 minutes to setup, it hasn't broke even though I dropped it multiple times, simple to charge and easy to use, definitely should get it if your want a durable and easy to use head strap.

## Features

- 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.
- Dual Fast Charging: Charge your Quest 3S/3 and K4 Boost twice as quickly. In approximately 2.5 hours, fully recharge using a 45W adapter (not provided). The K4 Boost and HMD both receive a 65% charge in 60 minutes, allowing for 2.5 hours of playback.
- 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.
- Unique gift for Kids: A great gift idea for boys & girls, perfect for birthdays, Christmas, or any special event.

### ⭐⭐⭐⭐⭐ A complete must have for the Meta Quest
*by J***F on December 31, 2025*

If you own a Meta Quest and you’re still using the stock headstrap that comes in the box, do yourself a favor and get this Kiwi headband. Seriously. I don’t know why Meta even bothers including that flimsy strap they ship with because it’s honestly terrible in comparison. I put up with the original strap for way too long. It was always sliding around, putting all the weight on my face, and leaving those annoying red marks on my cheeks after every session. I’d have to constantly readjust it and after maybe 30 or 40 minutes my face would start hurting and I’d have to take a break. Not exactly ideal when you’re in the middle of a game or watching something. This Kiwi headband completely changed the experience. The difference was obvious the second I put it on. Instead of all that pressure on my face, the weight is distributed way more evenly and a lot of it shifts to the top and back of my head. It sounds like a small thing but it makes a huge difference when you’re actually wearing it. Installation was pretty straightforward. Took me maybe ten minutes and I’m not particularly handy with this kind of stuff. The instructions were clear enough and everything clicked into place without any issues. No tools needed or anything like that. The build quality feels solid too. It’s got a nice rigid structure that holds its shape but there’s padding in all the right places so it doesn’t dig into your head. The back has this cushioned area that cups the back of your skull and honestly it’s just comfortable. I’ve done two hour sessions now without any discomfort which was absolutely not possible with the stock strap. The adjustment mechanism is also way better. You can dial it in to get the perfect fit and it actually stays put. With the original strap I felt like I was constantly tightening it because it would loosen up while I was playing. This one I adjust it once at the beginning and I’m good to go. My kids use the Quest too and we all have different head sizes, but it’s easy enough to adjust between users that it’s not a hassle to share. Quick twist of the dial and it fits whoever is using it. I honestly can’t believe how much better the Quest is with this headband. It went from something I’d use occasionally because it got uncomfortable to something I actually look forward to putting on. If you’re on the fence about upgrading your strap, just do it. You won’t regret it. One of the best accessories I’ve bought for my Quest hands down.​​​​​​​​​​​​​​​​
