K4 Boost Battery Head Strap for Meta Oculus Quest 3/3S, Adjustable VR Headband Accessories with Dual Charge, Extend Playtime & Reduce Facial Stress for Kids and Adults

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.

I've tried this strap and the bobo vr s3 pro. 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.

After searching for quite awhile, I found this absolutely perfect battery extended head strap. I was not wanting something separate that attached to the back, this is built in and actually balances the whole headset so it's even more comfortable with balanced weight on the head. Just love the fact that my headset is not dying after an hour of play. Excellent product!!

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.​​​​​​​​​​​​​​​​

Very comfortable, the battery is very nice, my only issue is that it feels slightly less secure than other elite straps but still far more secure than the original strap. It’s a little big for my head but I have a small head. Something else nice is by plugging the battery into the headset and plugging the strap into a charger you can charge both at once with one cable. If you are thinking about buying it, go for it, very durable very premium feel. Would buy again

This head strap is fantastic. Light, comfortable and well-balanced. Very simple to assemble, and keeps it's shape/sizing once you dial it in. Great purchase, Buy with confidence. That being said....a couple things to be aware of. 1. The battery CONSTANTLY powers the headset, even when it's off. When done charging, unplug the head strap battery cable until you use the headset again. 2. If sitting back in bed, or a high backed chair you can feel the battery pack against the back of your head. It's NOT uncomfortable, but you are aware of it's presence. 3. Threading the top of the head strap thru the center opening (over eyebrows) hole is really tight. Put a piece of masking tape over the end of the Velcro and feed that thru 1st. It pulls thru in seconds. You'll save a ton of aggravation. A great headset. No regrets. Adds an hour or two to your battery life.

Looks just as pictured. Easy to assemble, comfortable, doubles your playing time and charges quickly. Between the top strap and wheel on the back, it can be adjusted quite easily and helps stabilizes headset better than with original strap.

Easy to use and put together on the VR. The durability and quality is very impressive. The adjustment knob on the back is very easy to use and its very comfortable to wear.

Dans le cadre d’un usage régulier de la réalité virtuelle, j’ai eu l’occasion de tester différents accessoires, et le KIWI K4 se distingue clairement par la qualité de son expérience utilisateur. 🎯 Un vrai gain de confort Dès la première utilisation, la différence avec une sangle classique est évidente. La répartition du poids est beaucoup plus équilibrée, ce qui réduit considérablement la pression sur le visage. Le maintien est stable et confortable, même lors de sessions prolongées. 🔋 Autonomie prolongée La version avec batterie intégrée est particulièrement intéressante : elle permet d’augmenter significativement l’autonomie du casque. C’est un vrai plus pour les utilisateurs réguliers ou les sessions longues. ⚙️ Utilisation simple et efficace Installation rapide, ajustement précis grâce à la molette, et excellente stabilité une fois en place. Le produit est clairement pensé pour un usage quotidien. 🧪 Méthodologie de test J’ai évalué ce produit dans différentes conditions : sessions de jeu, visionnage de contenus, utilisation prolongée, et avec plusieurs utilisateurs. Cela permet un retour réaliste, objectif et représentatif d’un usage quotidien. ⚠️ Points à noter • Légèrement plus lourd qu’une sangle classique • Investissement plus élevé, mais justifié par le confort et les fonctionnalités ✅ Verdict Le KIWI K4 améliore nettement l’expérience VR, tant sur le confort que sur l’autonomie. C’est un accessoire que je recommande particulièrement aux utilisateurs réguliers souhaitant optimiser leur casque.

Love it! Quest 3 should come installed with a strap like this. Comfortable and well made. Makes the quest 3 feel much more balanced and comfortable to wear. The battery pack is just what I needed to extend my playing time. Overall excellent product. Will buy again for other family members.

Das hier ist mein erstes Headstrap und somit habe ich keinen anderen Vergleich als zum orginalen Headstrap von Meta was bei der Quest beiliegt. Zuerst einmal möchte ich dazu sagen, das die Verarbeitung des Kiwi Headstrap wirklich gut und hochwertig ist. Die Montage ist wirklich kinderleicht, ich als handwerklich unbegabter, konnte das alte Headstrap innerhalb von ein paar Minuten wechseln. Das Kiwi Headstrap lässt sich sehr einfach auf den Kopf setzen, es passt immer direkt und muss mit den gut zu erreichenden Kopffixierer nur festgezogen werden, was alles zusammen nicht länger als ein paar Sekunden benötigt. Da man das Headstrap von hinten bis zur hälfte nach oben klappen kann, muss man als Brillenträger sich nicht mehr in die Brille zwängen und den Abstand justieren, man kann direkt exakt und einfach in die Brille schlüpfen. Die Kopfstütze und das Kopfband sind sehr bequem und mit dem Orginal nicht vergleichbar, der Komfort des Kiwi Headstrap ist dagegen fantastisch, weich und sehr angenehm, sich den Kopf anpassend. Das Gewicht des Akkus und Headstrap spürt man schon leicht am Hinterkopf, aber nicht ansatzweise so stark wie mit dem orginalen Headstrap an Vorder und Rückseite. Durch die Form wird das Gewicht von vorne zusätzlich nach hinten verlagert und es fühlt sich allgemein viel leichter und besser an als mit dem Orginal von Meta, der Kopf wird viel weniger belastet und alles ist viel angenehmer und bequemer. Dadurch gibt es auch keine bis wenige Druckstellen im Gesicht, auch nach längeren Spielzeiten. Der Akku ist fest verbaut, hält bei mir +2 Std, lädt sich in einer normalen Geschwindigkeit auf, durch Lichter am Batteriestrap wird der Akkustand abgelesen und durch einen Anschluss unten aufgeladen. Mein Fazit ist, das jeder seinen Komfort, seinen Spielspaß und Spielzeit mit diesem Headstrap von Kiwi viel verbessert. Ein 100% Kaufempfehlung für jeden Qurst 3 Besitzer. Zudem ist das Preisleistungsverhältnis wirklich gut. Ich bin vollkommen zufrieden mit dem Produkt.

For me this perfect balance between comfort and stability. I like the Quest 3 original strap for stability, I can move my head around in fast games and keep a sharp sweeet spot, it does not move. But it’s awfully uncomfortable after 10 minutes. I tried a Kiwi Design H4 Halo strap, and while it’s very comfortable and fixes that issue, it introduces a new one for me as it’s so vobbly! In faster games I quickly lose my sharpness sweet spot (I use prescription inserts) because it moves around so much and it just does not feel like I get the ultimate picture quality. I am also aftraid to move my head around and that does not feel natural. Well I am glad to say this K4 Boost with battery solves both issues and is the perfect balance between comfort and stability! It’s way more comfortable than the original strap, but without sacrificing the stability! So feels much more natural than a Halo for me. Don’t belive all those ”Halo is better!” on the internet. Maybe if you are a youtuber and use it more than 8h a day, but if you are a regular user and want to get a one or two hours of gameplay after work, this is just perfect! Also battery is perfect, not a problem I can’t change them like in Bobo variants. It gives double amount of battery time and that’s plenty for me, I would never play VR more than 2 hours anyway without a break. And then you can fast charge it if you want, I have not tried fast charging but should work pretty quickly.

This is must to have product for metquest 3. Not worried about the battery backup now. I bought one pouch also from Amazon (grey colour one) , and the good lart is, with this head strap, I was able to get it inside that pouch (not that easy though). Kiwi can think of a pouch as well which suits the stap easily.
