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

Whoa, where do I even start with this? So, okay—KIWI Design, you know them, right? They throw out this thing called the K4 Duo. It’s supposed to be this big-deal head strap for the Quest 3. I mean, you can stick it on both the Meta Quest 3 and this 3S thing.

But here’s the kicker: it’s not just your run-of-the-mill head strap. Nah, it’s got these funky adjustable speakers on it. Like, you can twist them around or something. Sounds cool? Maybe. Anyway, the official name? Brace yourself for this mouthful: ‘K4 Duo AIO Audio Head Strap with Battery’. A real tongue-twister. And get this, there’s some magic switch thingy that lets you jump between headset audio and the K4 Duo’s sound. Plug it into the USB-C port and voila!

Now, battery life… yeah, it’s got this 2650mAh capacity. Don’t ask me how long that lasts. The whole setup weighs about as much as two cans of soda—459 grams, if we’re being precise, which I’m not usually. A few other tidbits like this fancy wheel to tighten it up, charging happening on two fronts, some memory foam padding that kind of just hugs your head, and a strap up top.

Honestly, we need to put this through its paces before deciding if it makes the cut for our all-time favorite list of Quest 3 gadgets. Last year we kinda loved this other thing, the K4 Boost or whatever, so maybe there’s hope.

Bottom line? If you’re itching to try it out, it’s hanging out on KIWI’s site, staring you down with a $159.99 price tag. Go see if it’s your jam.
