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 on Reviewed in the United Kingdom 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. ## Frequently Bought Together - KIWI design K4 Boost Battery Head Strap for Meta Oculus Quest 3/3S, Adjustable VR Headband Accessories with Dual Charge, Extend Playtime & Reduce Facial Stress - Meta Quest 3 512GB — Ultimate Mixed Reality Experiences — Get Batman: Arkham Shadow and a 3-Month Trial of Meta Horizon+ Included - AMVR FC3 Upgraded Comfort Face Cover Pad Facial Interface Compatible with Meta/Oculus Quest 3 Accessories, with Knob Adjustable, with PU Face Cushion and Breathable Ice Silk Cotton --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/656919069-k4-boost-comfort-battery-head-strap-accessories-for-meta-oculus](https://www.desertcart.no/products/656919069-k4-boost-comfort-battery-head-strap-accessories-for-meta-oculus) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-23*
