KIWI design K3 Boost Battery Head Strap Compatible with Meta Quest 3/Quest 3S, 6400 mAh Battery Pack Head Strap Accessories, Fast Charging & Reduce Face Stress

When I purchased this headstrap and battery combo I was looking to improve on the original Quest 3 comfort. I looked around online for a decent headstrap and kept finding people were getting better results when a battery pack was helping distribute the weight from the overly front heavy HMD. I saw that this product by Kiwi had lots of good reviews and for the price, decided to give them a chance. I must say, I don't regret it at all! It in fact has been a great little addition to the Quest 3. I'm writing this review over 1 year after purchase, and I can't stress I am very pleased with it. Fits great for me, makes the HMD better balanced which improves stability. Not to mention it was at a great price when compared to Meta's version. The head strap has a padded area that helps with improving fit and comfort, as well as at the back of the head.Over a year now with it and it still providing extended times. I'm not a heavy user though and never took the time to track how much additional time it gives, but it is much more than the standard headset provides. I know that much because I've been in situations where I learned the hard way about the Quest 3 desire to stay on despite shutting it down which left me only the HMD's internal battery to use. That, did not last long the times I've used it as such.So I was surprised on several occasions when I picked up my Quest 3 and saw the HMD was running on its own internal battery. The Kiwi battery was discharged. I found it weird because I left it fully charged over night before unplugging the Kiwi battery from the wall charger. Little did I know that what happened was that the HMD after being shutdown, continues to operate a state of charge indicater, while it remains plugged to a power source. That is, because the battery was plugged to the HMD (the Quest 3), the HMD considered it a regular charger and continued to run the face sensors and battery SoC sensors. If you activated the sensor by using a cover on the lenses you would even activate the display. My thoughts are that the designers realized they have no external way of showing SoC of the battery on the Quest 3. So they decided it would just turn on the screen to show you the SoC of the battery.The point is, because the battery was plugged into the HMD the HMD did not fully shutdown draining the battery. Once I found out about that I began unplugging the battery from the HMD when I was done. Which pretty much solved that issue instantly. That is by far not a problem from this product but rather a behavior of the Quest itself. Now, again, I'm not the most verse individual with the Quest 3 but I know a thing or two, so I'm almost ashamed to admit I didn't really learn thoroughly my Quest 3. It took me forever to learn about the facial interface and how it can be adjusted for things like wearing glasses. I had a period of use with this headstrap and battery where I still felt as if the weight was heavy on my face. Almost like I wasn't getting even distribution. I felt the pressure most on my nose. I adjusted the distance between the eyes several times to see if I was just pinching it. Well, when I finally found out about the facial interface adjustments I immediately felt the results. No more pinched nose and the weight seemed to lift off my face. Before, using the original straps, the headset felt when loose like it would slide down my face and when tightened it felt like it would pop off over my head. With this, the headstrap feels well placed on my head and doesn't feel like it would either fall or pop off.I highly recommend it for anyone with a Quest 3 (I can't speak for any other Quest, I only own the 3).

This strap and battery upgrade made so much difference. The strap is so comfortable on my head and the weight of the extra battery on the back is balanced just right with the headset. It doesn't pull on the back of your head like the original strap does. The play time is long enough that i quit playing before the battery runs out. Unlike before when the battery low warning would pop up in the middle of the game and I would have to stop right then to recharge for about 2 hours. The charge time is the same as before. Its very easy to replace the strap. It's also very adjustable with just the turn of a knob. You get, comfort, time, and ease of use for a great price. It also fits most carrying cases. I thought I was going to need to buy a new hardshell carry casr for my Meta Quest 3s after I installed the strap with battery but it adjusted down to a perfect fit in the case. This is a must have for any Meta Quest user.

Having owned a quest 2 and never buying a different head strap for it, I didn’t want to end up in the same situation with a quest 3. The stock head strap (combined with the stock facial interface) becomes very uncomfortable after maybe 15-30 minutes of use. I spent quite a bit of time researching which strap to buy and I’m sure like a lot of you I was between the bobo m3 pro and this one.I actually found myself leery of the bobo after seeing how many different reviewers were pushing it. It felt more like a sponsored rather than a good product. Due to sensing this I decided to go with kiwi strap and I’m glad I did as I’ve gotten the chance to try both now and feel I made the right decision.I purchased an aftermarket quest 3 for my girlfriend after seeing how much she liked it. This one came with the bobo vr strap mentioned. Comparing the two I’ve found the kiwi:1. More comfortable, the top strap really seems to be a necessity for this.2. Has a longer lasting battery, the two are very similar but it’s notable.3. Is much easier to just throw on and quickly adjust. It takes seconds to get this back in a comfortable position which is a godsend if you need to clean the lenses while playing beat saber or the like. The bobo m3 pro felt more like I was installing an apparatus on my head and didn’t have quite the same range of adjustment.I will say there is a benefit to the bobo strap, having a swappable battery seems like it would be great if you’re playing for a long time or if you forget to charge the headset after using. If you think you’re going to be playing for more than few hours at a time it may be worth it to go with that one. If you’re looking for comfort, like I was after dealing with stock quest 2 equipment, go with this one.In addition to this strap I also bought the kiwi controller grips with battery door. There’s a ton of copycat designs for around the same price, I just went with that one because I was already getting this strap and there was a percentage off. I bought the amvr facial interface with the “ice silk” cover as well. These three things together have made the quest comfortably playable for hours at a time when I would have started to feel uncomfortable after only 15-30 minutes previously.Go with whichever strap seems best for you, but if you for example find yourself leaning one way or another due to YouTube channels with $10s of thousands of dollars of vr equipment but a number of subscribers that seems low for their production value, I’d question the true nature of their review.

First let me mention that i purchased this for $60. Days later this is discounted for $40. That was annoying, i may should have bought it on eBay which was on those prices...Now for the normal review: The strap is comfortable if its not too pushed in, so make sure to find your spot. Battery works like a extended one, not as a backup. What i mean is that you should have the headset charged at the highest percentage, then you plug the battery in. Is not fast charging, just sitting on the percentage you got on the headset. Which makes it last for about 2 more hours, haven't been able to fully drain it out on a single session yet (Maybe i will on my day off).I liked the elite style headstraps more than Halo ones for a simple reason: the headset doesn't wobble. Is pushed into my face rather than sitting on it.The included cloth may scratch the lenses btw.
