K4 Boost Comfort Battery Head Strap Accessories for Meta/Oculus Quest 3/3S, Dual Charge the VR Headset and Battery Strap in 2.5h

Infinitely more comfortable and easy to use this strap and extra battery for a very reasonable price

Recently bought the Meta Quest 3, had already read the issues with the standard head strap that comes with it being uncomfortable.With that in mind, I wanted a more premium head strap and the extra battery power to be able to use it longer. This is a lot more comfortable to use, spent a few hours using it before writing this just to compare and the difference is immediately noticeable. Didn’t feel any discomfort while using the whole time, not at all overly heavy with the additional battery, was easy to attach to the Quest 3 and all connects together perfectly. Head strap can also be easily adjusted for a nice fit while using to keep it secure.Included non-removable battery was almost fully charged when it came, when connected and charging, it charges both the battery in the head strap and the battery in the Quest 3 at the same time which is great. It doesn’t come with any charging cables or additional plugs, not an issue though as you can just use the plug and USB-C cable that comes with the Quest 3. After a few hours of use the battery on the Quest 3 was still full and also had 1 of 4 lights on the head strap battery still available.Overall if you’re after something comfortable that also has the extra battery power then I have no issue at all recommending this. Very good value for the cost, will make your VR experience last longer along with more comfort in the process.

Good head strap and comfortable to wear with the padding. Feels durable and size adjustability is good. I find the battery design useful for a quick top up if I want to extend my session by 30 minutes, or when I forget to charge the quest! Easy to attach to the headset.

I bought this after doing a lot of research as to why I'm getting serious pressure points from the original quest strap. It just didn't feel comfy and didnt feel like it fitted snug. With this head strap the headset feels fitted and doesnt move when being used on the energetic, fast paced games. Its very adaptable as you can dial the size in at the back of the strap, make the top strap shorter or longer (its just a velcro strap so easy to alter) and the battery really boosts the battery time on the headset. I'd say it doubles it. The lenses can steam up when I first put it on but that soon settles or I wipe the lenses and it's good to go. I find I can wear the meta quest 3 headset for longer now with this strap attached, it's so much more comfortable. Happy customer.

Absilutely fantastic had it for nearly 2 years now won't ever go back really conpfortable and easiy to use, just got to make sure got the correct cavles to use properly

The Kiwi Design K4 head strap is a huge improvement over the default strap that comes with the Meta Quest 3. The added comfort is immediately noticeable—the padding is much softer, and it distributes the weight more evenly, making long gaming sessions way more comfortable. The adjustable design fits perfectly, and I love that it feels more secure on my head.The battery feature is a game-changer as well. Having the extra power pack integrated into the head strap extends playtime significantly, and I don’t have to worry about my Meta Quest 3 running out of battery so quickly. It’s a fantastic upgrade overall and really enhances the VR experience.Highly recommend this head strap if you’re looking to improve comfort and battery life. It’s definitely worth the investment!

This is great, I'm sure the battery lasts longer than 2 hours on this. I've definitely played for 3 hours and it had 1 bar left and the full headset battery. Very comfortable and holds the headset stable on your face. A nice amount of adjustability to keep it comfortable.

Very comfortable, reduces pressure on the forehead making it easier to play for longer. Installation is also simple enough, the only difficult part was removing the facial interface from the quest, which is in no way a problem related to the KIWI product.

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 confortDès 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 prolongéeLa 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 efficaceInstallation 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 testJ’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✅ VerdictLe 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.

The K4 Boost Comfort Battery Head Strap is a great add-on for my Quest 3S. It makes the headset feel much more comfortable, with the balanced design taking a lot of the weight of the headset away from your face.The built-in battery extends the headset play time by around 2.5 hours. When connected, the strap battery is used first before the headset battery, which is a sensible way for it to operate.Installation is very simple and only takes about 30 seconds. Charging time is also quite fast, roughly the same as charging the headset itself. A handy bonus is that the strap can remain plugged into the headset all the time, and charging the strap will charge both the strap and the headset together.If you want a more comfortable headset with roughly double the run time, this is a very worthwhile upgrade.

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.
