Kawaye Battery Head Strap 15000mAh for Meta Quest 3/Quest 3S/Quest 2, Adjustable Elite Strap with Detachable Battery Pack x2&Charging Dock,VR Accessories Enhanced Support&Comfort Extend Playtime

Quality product
Very comfortable. Fits great. Great value for the money. Functionally is great and we received it before expected.

Works well
The item does what it says. It took me a while to figure out how to put it together because the instructions are really almost useless. The refer to your headset as “the host” and refer to parts by cryptic names and the diagrams are hard to understand. I was able to figure it out by trial and error. No tools needed. I have MetaQuest 3 so be aware that the side straps snap right off. Don’t unscrew something and break it. It took me a bit to get the fit right because I have a giant head. It works great and gives plenty of battery life. Batteries are swappable so you use 1 at a time. Though not mentioned in the instructions, the little black square cap is the cradle is where you can charge your batteries. It has a port to plug into a usbc cable. I was very happy with the purchase once I figured it out and no longer worry about running out of batteries.

Very comfortable
The strap provides a balanced load across the face and head, making for much more comfortable play. The two batteries allow for hours of continuous play.

Excellent Choice
This is the second external battery/head-strap I have purchased for my Quest 3. The first’s one’s ratchet gave out after a few months. One side worked and the other was floppy and wouldn’t tighten down.This one has two ratchets, One to adjust the fit to the top and the other to adjust the circumference around at the forehead. I finally have a sense of confidence with it’s engineering. The good things? The external battery balances nicely on the back of the head and the ratchet’s tighten down securely allowing for rapid movement without the headset bouncing around. It also has two batteries which are charged externally allowing you to change them when you run out of juice. So far, I have only had to use one of the external batteries but I do swap them out to get equal wear and tare. The hinged headstraps allow you to adjust and move the face-plate up or down and don the unit quickly once you’ve adjusted it to your liking. No more constantly adjusting the straps and ratchets to get a comfortable fit. Now I’m in the game in seconds. I also find that the face-plate no longer rides on my cheekbones making marks that last for hours. I love it. I will edit this review if my opinion changes but this first week has been a welcome relief. Buy it! I think you will be happy with it even if it does cost more. It’s worth it for the additional batteries and the design. WAY more comfortable that the others.Ten days later, using it every day. Still LOVING IT! Worth the extra $$$. So far, no disappointments.

Update: after about 3 weeks, both battery wouldn’t charge up past 20%, even if left overnight, so I have revised the rating (originally gave a 4 star) and I have no choice but to return it..Original posting:The headset on this is not the most comfortable (compared to Aubika for example), but it had better battery life than the Aubika one (which I had to return). It comes with 2 batteries which you can swap, each seems tp provide about 2 hours of charge. The charging button works well – like 1 press to turn it on and 2 presses to turn it off, except that it works as it should (unlike the aubika one I tried). The headset seems flimpsy and plasticy, but still, it is comfortable to use for a hew hours without any problems at all, but it is not the msot comfortable I’ve tried (which is why I rated it at 4 instead of 5 stars). Still, I am happy with it because the battery works well.
