Review: Good but expensive - Lovely and comfortable as you would expect from the KIWI brand,love the touch to add built in headset..probably done this as no one else has and to keep relevant.Over 4 hours extra battery life so its a game changer. It's expensive £130,is it worth it? In all honesty as good as it is NO its not worth that expense that's alot of money in this age where people watch what they spend with bills rising,but if you want the best and a great extra battery life compared to the previous model and willing to pay..this in my opinion is it
Review: Big upgrade over the standard head strap - Recently bought the Meta Quest 3, had already read the issues with the standard head strap that comes with it being uncomfortable. With that in mind, I wanted a more premium head strap and the extra battery power to be able to use it longer. This is a lot more comfortable to use, spent a few hours using it before writing this just to compare and the difference is immediately noticeable. Didn’t feel any discomfort while using the whole time, not at all overly heavy with the additional battery, was easy to attach to the Quest 3 and all connects together perfectly. Head strap can also be easily adjusted for a nice fit while using to keep it secure. Included non-removable battery was almost fully charged when it came, when connected and charging, it charges both the battery in the head strap and the battery in the Quest 3 at the same time which is great. It doesn’t come with any charging cables or additional plugs, not an issue though as you can just use the plug and USB-C cable that comes with the Quest 3. After a few hours of use the battery on the Quest 3 was still full and also had 1 of 4 lights on the head strap battery still available. Overall if you’re after something comfortable that also has the extra battery power then I have no issue at all recommending this. Very good value for the cost, will make your VR experience last longer along with more comfort in the process.

### ⭐⭐⭐⭐ Solid
*by P***P on 7 November 2025*

Good head strap and comfortable to wear with the padding. Feels durable and size adjustability is good. I find the battery design useful for a quick top up if I want to extend my session by 30 minutes, or when I forget to charge the quest! Easy to attach to the headset.
