Meta Quest 3/3S用 K4 Boost バッテリー付きヘッドストラップ

I love it

The product is awesome, gives extra comfort with additional 2 to 2.5hrs game time. Easy to install and o love it.

I’ve ordered from Kiwi Design and I am very satisfied. I did have an issue with a shipment, but their customer service team was super-helpful and responsive in resolving it. In the end, everything was shipped promptly, and I received my items as expected. The strap itself is of great quality and I enjoy using it.

Es bueno pero me salió con un problema en el que no encaja bien por el lado derecho y hace que quede un poco suelto pero sin llegar a caerse.

I've been using Kiwi head straps for years now. They didn't disappoint with the new K4 Boost. The recessed adjuster knob, the shortened charging cord, the ability to fast charge, and the continued padding are all great. The only thing I would like now is the ability to charge it like the SPC battery head strap with their dock. But maybe a new dock will come out soon anyway.

I got about 3 extra hours of game time with this. The charge time as mentioned is really fast especially when you use the 45W charger made by Kiwi.

Fantastic product it extend your VR Gaming experience up to 4.5hrs in total. Very comfortable and very good balance in weight. Great for long gaming playtime. Game changer. Very Impressed with quality.

I have used the old Kiwi Headstrap with my Quest 2 for two years.
So this time, for the Quest 3, I ordered the K4 Boost Battery Headstrap, and it's even better.
The comfort level and battery are perfect, and the hidden control at the back looks neat and convenient.
If you do not already have a 45W charger, you must buy one to make the best use of the battery head strap.

Excelente

It is so comfy and it helps my battery life longer

Falls off randomly

Great! Love the comfort and added playing time

Great for grinding on games so if your quest is about to die you plug the battery in and your good and also it has great comfort

I do live in New Zealand and found the name ( Kiwi Design) / location ( China ) of item i little miss leading but its very nice to use.

The strap is very easy to put on. It adds comfort to the strap that comes standard with the Meta Quest. The extra battery provides a lot of extra usage time and it's very useful that it can be charged at the same time as the Meta Quest.

We did not like the H4 as much as the K4 we purchased for our sons headset (to much pressure on the forehead, gave us headaches) so we returned the H4 and ordered another K4 which we are happy with. However we have not received our refund yet.

Perfect

best strap i’ve used

The items never arrived to me

He's amazing to charges very like low it's not getting like 2 hours but it's fine and is great just more comfortable and fine

Set it up within minutes, it’s so easy to adjust and it improves comfortability a lot if you’re coming from the stock quest 3/3s headstrap. The battery seems to do the job, I haven’t played anything really intensive but in what I have played the battery seems to keep up with charging. Charging the battery and headset at the same time isn’t an issue either, I’m only using the charger that came with my quest and I’m not noticing any major speed problems.

The only minor problem I have with it is the build quality; seems to be quite flimsy around the part that actually attaches to the headset and the hinge. However that’s being picky as it doesn’t really cause any issues, just something I thought I’d mention considering the price point.

Love thus head strap very comfortable and very high play time this js a very good headstrap you should try

Kiwi continues to impress! My quest 3 went from painful within 10 minutes, to comfortable as long as I want to play. This is my family's third kiwi product and I will continue to recommend them highly!

K4 Boost Battery Strap for Quest 3/3S

I have to tell you that Kiwi has such a great fitting straps for the quest two and the quest three. The adjustable dial on the back, makes it absolutely the best thing ever. And don’t get me started on how great day hand grips are on both the quest two and the quest three love all the kiwi designs.

The extended battery & is different strap from the default definitely makes the whole vr experience way better.

Almost perfect. I'd want a button to turn on or off the external battery, so it's not trickle charging when not in use. Instead I have to pull out the charger's cable, which is just more unnecessary strain on my Quest's USB-C port. Hope I don't damage it, as it's a pain to replace. Fit and quality is good. Might not have bought it if I had known of this issue, but I am satisfied with the product.
