New Audio Head Strap for Quest 3 & 3S: Introducing the KIWI K4 Duo

Alright, so KIWI Design’s got this new thing—it’s called the K4 Duo. Crazy, right? It’s a head strap jazzed up for the Quest 3—a whole audio and battery circus in one go. These guys have done it again, sticking this contraption onto both Meta Quest 3 and 3S. You can mess around with the speakers—rotate them like those old-school car mirrors—plug them into the USB-C, and voilà, you’ve got options. Is it just me, or does this feel like magic?

So, the battery’s got some kick. It’s 2650mAh, which sounds big enough, right? Weighs in at 459 grams—feels like holding some fancy European baguette. Features? Sure, it’s got the “twist-and-tighten” wheel, duo charging (yes, your headset too), and some plushy foam padding that feels like clouds on your head. Oh, and a top strap. Who knew straps had so many personalities?

We’re still fiddling with it—need to poke and prod before it gets a golden star on our list of fancy Quest accessories. Last time we tinkered with KIWI stuff, it worked out pretty sweet—the K4 Boost was our go-to battery strap back then. Good memories.

Anyway, scratch that—wait, where was I? Right, if you’re itching to dive into this, KIWI’s got it online for $159.99. But hang on; we might shift the deck and update our favorite picks soon. Or not. Guess time will tell.
