This one fits me more comfortably. I have a very large head. I ended up keeping the k4 boost and giving the bobo vr strap to my son, it fits him much better than it fits me. The battery life seems sufficient with this strap and it is easy to charge the strap and the headset together. For best results you will need to buy a 45watt charging brick it is not included with the strap and the brick supplied with the headset is only 25 watts. The one conplaint I have is if you leave it plugged into the quest when you arentnusing it, it will drain the battery in the strap a little even if the headset is fully charged. There is no power button like the bobo s3 has. So you need to unplug it from the headset when the battery amd the headset have reached full charge before storage. Overall im happy woth my purchase. Its loads more comfortable than the stock strap and opens and closes to accommodate any head size. Review: Best Bang For Your Buck - This product is amazing ! May be a little more expensive than other competitors but it’s worth it!! Feels snug , comfortable and light on the head even with the built in battery pack! The life on the headset definitely helps the gameplay session last longer too ! It easily adjusts to the head as well! I have a big head and my fiancee has a much smaller one so it’s easy to adjust and fits us both perfectly ! But Now that my fiancee is getting a meta quest 3 as well I think I’m gonna have to order another one for her ! Unless Kiwi would like to send me a free one for some extra publicity ;) haha! ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D4TGY2F2 | | Additional Features | Adjustable Headband | | Age Range Description | Teens, Adults | | Battery Average Life | 3 hours | | Battery Capacity | 3 hours | | Best Sellers Rank | #883 in Video Games ( See Top 100 in Video Games ) #12 in Standalone Virtual Reality Accessories | | Brand | KIWI design | | Built-In Media | Headstrap | | Color | White and black | | Compatible Devices | Meta Quest 3/3S | | Connectivity Technology | USB | | Connector Type | USB | | Controller Type | Knob Control | | Customer Reviews | 4.6 out of 5 stars 2,337 Reviews | | Display Maximum Resolution | 1832 x 1920 per eye | | Display Resolution Maximum | 1832 x 1920 per eye | | Display Type | LCD | | Field Of View | 52 degrees | | Included Components | Headstrap | | Item Weight | 12.8 ounces | | Manufacturer | Shenzhen Hongjiantou Technology Co., Ltd. | | Mfr Part Number | QS02B | | Model Number | QS02B | | Number of Items | 1 | | Operating System | Oculus Integration | | Platform | Meta Quest | | Resolution | 1832 x 1920 per eye | | Sensor Technology | inside-out tracking | | Special Feature | Adjustable Headband | | Specific Uses For Product | Gaming | | UPC | 850052498382 | | Unit Count | 1 Count | | VR Operating Platform Compatibility | Standalone | | Warranty Description | 2 year | ## Product Details - **Age Range (Description):** Teens, Adults - **Brand:** KIWI design - **Color:** White and black - **Compatible Devices:** Meta Quest 3/3S - **Connectivity Technology:** USB - **Field Of View:** 52 degrees - **Included Components:** Headstrap - **Operating System:** Oculus Integration - **Special Feature:** Adjustable Headband - **Specific Uses For Product:** Gaming ## Images ![KIWI design K4 Boost Battery Head Strap for Meta Quest 3/3S | Adjustable VR Headband Accessories with Dual Charge, Extend Playtime & Reduce Facial Stress for Kids and Adults - Image 1](https://m.media-amazon.com/images/I/61hPO7ZnTsL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best quest 3 strap I have tried *by A***Y on January 24, 2026* I've tried this strap and the bobo vr s3 pro.

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.​​​​​​​​​​​​​​​​ ## Frequently Bought Together - KIWI design K4 Boost Battery Head Strap for Meta Oculus Quest 3/3S, Adjustable VR Headband Accessories with Dual Charge, Extend Playtime & Reduce Facial Stress - Meta Quest 3 512GB — Ultimate Mixed Reality Experiences — Get Batman: Arkham Shadow and a 3-Month Trial of Meta Horizon+ Included - AMVR FC3 Upgraded Comfort Face Cover Pad Facial Interface Compatible with Meta/Oculus Quest 3 Accessories, with Knob Adjustable, with PU Face Cushion and Breathable Ice Silk Cotton --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/659836782-kiwi-design-k4-boost-battery-head-strap-for-meta-quest](https://www.desertcart.nz/products/659836782-kiwi-design-k4-boost-battery-head-strap-for-meta-quest) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-08-21*
