    • Comfortable light weight fit
Swapped out the original Meta Quest 3 strap with this one for more comfort and extended battery life/play time. The weight and fit does not bother my neck or head which is sensitive to just about anything I wear on my head. Battery life is not the longest but is a good built in time limit that prevents me from spending to much time playing games. Good value, easy to install and so far no quality issues. ... show more

    • This should is a game changer
I can't believe I waited so long to buy this head strap. Fit and finish feels better than oem, it is incredibly comfortable due to all the available adjustments and padding. It makes it so much easier for multiple users to utilize the headset without the hassle of cumbersome readjustments. The battery works seamlessly and adds a counter balance which makes the headset a bit heavier, but it feels much more secure. ... show more

    • Super Comfortable and Long Lasting!
Definitely an upgrade from their previous Generations of headsets for the Meta. Compared to the stock headband that the Meta comes with out of the box. This headset provides extra support, built in battery to charge the Meta quest while using it. Super comfortable and easy to install. Definitely worth getting, especially if there is a deal. I have not had any issues whatsoever, great brand. ... show more

    • Quite comfortable but slightly lacking
Overall between this K4 Boost and the H4 boost (halo style), this one is superior. The key part is because it is more comfortable and stable (in more active games) than the H4 boost [and it is cheaper!]. It definitely is one of the more comfortable headstraps (even comparing it to the S3 Pro it is comfortable, yes knowing that one is a halo style and this one is not). However, for me, a significant con is that its additional battery life is pretty short and you need to disconnect and reconnect the USB-C plug every time otherwise it will continue to slowly charge / drain battery even when the device is off. It also is relatively bulky around the back which makes it not too comfortable to lie back/down with it. ... show more

    • Must buy
This turned a good headset into a great headset. The battery life is very good, and this strap is easy to adjust and comfortable. Just make sure to buy the case for this strap. The zipper on the official case broke with this strap, because it was a very tight fit.

    • This is the Chosen One for me
I had purchased a Bobovr M3 Pro, Yoges, Kiwi H4 and Kiwi K4. I am new to the VR world, and have become quite active exercising with Supernatural. For me and my head, The K4 won hands down over the rest. It's comfortable and stays put for a vigorous half hour session. Having an old and arthritic neck, I woke up the first morning after its first use a bit sore but no soreness after that. It will make your headset quite heavy but it's balanced well with the battery at the back which adds another 2 hours of play should I choose to game after my workout. ... show more

    • Fit and feel is great but returning
I purchased this after doing some research returning. My initial research was centered around comfort and logentivity when the battery was in use. For that reason alone is a much better headset strap then the one provided. The biggest weakness is the battery drain that occurs when the headset is off. Of you fail to unplug it from the usb c connector, the Meta headset will continue to draw power from the Kiwi headstrap. The result, after about 24 hours the spare battery is dead. I'm unsure if this is a meta headset issue or with the strap itself but it's bad enough that I rather return it ... show more

    • Great for Standalone!
This head strap is great for extending play time on the Quest 3. It is extremely comfortable and the battery lasts way longer. The PC link cable doesn't pass through the port in the back, so you will have to unplug the battery cable to use it, but you don't really need the battery pack if you're using the PC link cable. ... show more
