The name speaks for itself
I’m so glad I bought the KIWI design K4 Boost Battery Head Strap for my Meta/Oculus Quest 3S! This head strap has genuinely improved my VR experience. The extended battery pack gives me longer play sessions without constantly worrying about running out of power, which is perfect for longer games and adventures. The adjustable design makes it super comfortable to wear, and I love how balanced it feels — even during intense gameplay. The strap fits securely and takes pressure off my face, so I can enjoy VR without discomfort. Installation was easy, and it feels very sturdy. I also like that it charges both the headset and the head strap quickly, so I’m always ready to jump back in. Overall, this accessory has added serious value to my VR setup — highly recommend it!

Quality Buy
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.

Best quest 3 strap I have tried
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.

Great Head Strap, but a couple things you should know.
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.

Quality strap
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

A complete must have for the Meta Quest
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.
