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

So, KIWI Design just threw another gadget into the wild—this one’s called the K4 Duo. It’s an audio and battery head strap for the Quest 3. And, just to make it clear right off the bat, it works with both the Quest 3 and 3S. Got it?

Now, here’s the thing—I mean, haven’t we all wondered about little adjustable speakers you can move around? Yeah, me neither, but KIWI thought it’d be cool. They’ve slapped on these “all-in-one” speakers, so you can twist ’em to wherever your ears decide they wanna hang out. Oh, and it’s got a fancy name: ‘K4 Duo AIO Audio Head Strap with Battery.’ Catchy, huh? You can even flip the audio source like a light switch, depending on whether you’ve got it plugged into the USB-C port or whatever.

Let’s talk numbers for a sec. The juice box inside—technical term, right?—is 2650mAh. And it’s not a weightless wonder; it’s clocking in at 459 grams. Everything else is pretty much what you’d expect if you’ve ever strapped one of these contraptions on your head. There’s this turn thingy on the back to squeeze your noggin, dual charging—’cause who has time to charge things separately—some memory foam that reminds you it’s still comfy-ish, and a strap on top. Did I mention it’s similar to what KIWI usually does? Because it feels like I did. Maybe twice.

But wait, let’s not slap it on the “best accessories” pedestal just yet. More fiddling—er, testing—is needed before we start handing out trophies. Last year, we fell in love with the K4 Boost Battery Strap. True story. It was our top pick for Quest 3. Will this new kid on the block dethrone it? Time will tell. Or it won’t. Who knows.

For now, if curiosity or the irresistible urge to own every single Quest accessory has bitten you, you can throw $159.99 at KIWI’s site and call it a day. Another gadget in the cart, another adventure awaits. Or maybe just another thing gathering dust. Your call.
