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.

Increased comfort, security, and battery life – highly recommended
I use my Quest 3s mainly for VR fitness apps such as Les Mills Body Combat and Thrill of the Fight. The standard headband left the Quest flopping all over my face while I was moving around during workouts. The Kiwi headstrap solved that problem. It was simple to install on the 3s, feels sturdy, and allows for a good custom fit on my head. It adds a little weight overall, but it is well balanced, so I don’t notice it when in the game. The 3s is held securely, and comfortably in place while I’m working out. And the additional battery life means I don’t have to worry about the 3s running out of juice before I do. For me, this is a great value and I highly recommend it.

Excellent Head Strap
Just like the one I had for Quest 2, KIWI doesn’t disappoint. Good fit, stability, and comfortable. The battery lasts quite a while, and the new passthrough charging is great. Well worth it, just get it!

⭐️⭐️⭐️⭐️⭐️ Must-have upgrade for the Quest 3!
I was skeptical at first, but the Kiwi Designs K4 Battery Boost Head Strap blew me away. Super easy to install and way more comfortable than the stock strap—feels like the weight just disappears.The extra battery life is a total game-changer. I can play or watch movies for hours without worrying about charging, and the battery on the back actually helps balance the headset better on my head.Build quality is top notch, feels sturdy yet lightweight, and the padding is really soft. Honestly, I don’t know how I used the Quest 3 without this. Worth every penny!

You never will go back to another headset.
This is a great head set. Very comfortable and adjustable for my head. Power lasts too!

Great fit; Very comfortable; Easy to install
Very easy to install. About 30 seconds to swap OEM strap for K4. All the parts fit perfectly.Immediately noticed the comfort difference. Wife wears glasses and says huge difference in comfort for her. A lot of negative reviews cite the battery capacity, which I don’t understand. You knew the battery size when you ordered it, so don’t complain when it is exactly what you ordered! I’m not a “power” user and don’t use the Quest for 6 hour sessions, so this battery will probably be fine for my use. Like the passthrough charging port and again, no complaints because of lack of an on/off switch. Unplugging the battery from the Quest takes all of 1 second. I can live with that. Overall, seems great, fits great and enhances the comfort and usability. Will upgrade to 5 stars once I use for a couple of months.

Amazing Head Strap if you prefer Elite Style Straps!
My favorite head strap by far. I personally prefer the elite strap style over the Kiwi H4’s Halo strap design due to it being more comfortable for my head shape and this is my favorite by far. The cushion for the back pad is incredibly soft, as always from Kiwi products. The design is very slim and minimalistic unlike other brands which go overboard and end up looking pretty tacky. The knob adjustment is very satisfying to use and you can easily push in this strap to quickly secure it to your head unlike the BoboVR E3 elite strap which requires you to manually turn the knob each time just to tighten it on your head. But by far my favorite part of the strap has to be the length of the wire that plugs into the Quest 3 headset as it’s only just long enough and doesn’t annoyingly stick out like many other head straps for no reason. It really adds to the clean look when put on the headset. In fact, this headset is so comfortable to use that I actually am able to remove the top head strap and secure it to my face without any issues to comfort or how secure it feels.

100% RECOMMEND FOR ANYONE THINKING ABOUT GETTING THIS!
This is honestly one of the best vr headstraps out there in my opinion. Would recommend for the comfort and extra battery of course!

Comfortable and extends battery life
Comfortable, extends battery life. Original strap dug into my head and the weight of the headset would make my head hurt after an hour. The Kiwi headstrap helps reduce the weight on my face while being comfortable. Just be sure to have a big enough case.

Franchement, le KIWI K4 Design Boost avec batterie intégrée est une vraie révélation ! C’est tellement mieux que la version originale — niveau confort, c’est le jour et la nuit. Le poids est mieux réparti, le casque tient parfaitement en place et les longues sessions deviennent beaucoup plus agréables.La batterie intégrée est un énorme plus : elle double facilement la durée d’utilisation du Quest, ce qui change complètement l’expérience. Plus besoin de se soucier de la charge en pleine partie.En résumé : confort, autonomie et qualité au top. Rien à dire, c’est un accessoire incroyable et clairement indispensable si vous jouez souvent en VR.

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.

I just bought it and found it very comfortable for my head and face, and made me able to extend my playing time maybe for an additional 1,5 hrs, also the material is good
