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

Sure thing, let’s dive into this. So, KIWI Design decided to throw out the K4 Duo—yep, another audio plus battery head strap for the Quest 3. Honestly, I sometimes wonder why I care so much about these things, but here we are. It’s like, compatible with the Meta Quest 3 and 3S—because, of course, why not mix it up with more versions, right?

This thing’s like a gadget-lover’s dream. You get these spinny audio speakers that just… rotate wherever. Officially, they call it the ‘K4 Duo AIO Audio Head Strap with Battery.’ Sounds fancy, huh? There’s this fiddly switch to jump between using the headset’s sound or the K4 Duo’s once you plug it into that USB-C thingy. Sure, simple enough, but why do I always press the wrong button?

It tosses in two 2650mAh batteries, and at 459 grams, it’s like holding, I dunno, a small melon on your head! Crazy, but then you’ve got these usual bits from KIWI: a back turn wheel for tightening—reminds me of adjusting my old roller skates—a dual charging setup, and memory foam that feels like a hug. Oh, and let’s not forget the top strap, though half the time it feels like it’s always tangled up.

We’re supposed to test this thing more, see if it lands on our ‘top accessories’ list. Feels like déjà vu—last time we raved about the K4 Boost Battery Strap, so maybe this one’s gonna make the cut too. Who really knows until you wear it, right?

Anyway, they’re selling this gadget, or contraption—I should say—on KIWI’s site and on Amazon. The price tag’s at $159.99, but who pays full price anymore? There’s a launch discount that makes it $139.99. Probably so they can say it’s on sale. But yeah, if you’re into this stuff, maybe check it out. Or not. Choice is yours.
