The cheapest rung on Cardo's kit ladder exists for helmets the other kits can't serve. Nothing inside it makes sound: by its own listing, the Half Helmet Kit is a cradle, a mounting clip and an extra-long boom microphone for hanging a Packtalk unit on a half helmet, a ski helmet or anything else with no ear cavity to hide hardware in.
The listing promises a cradle in the box, and the owners disagree. Three of them describe the same gap between the page and the contents, and one dates it precisely: the Bold-era version included the cradle, the Edge-era version doesn't. That fight is the spine of this review, and it sits inside a record with an unusual shape, where the biggest non-five-star band is the three-star one.
Below: what the kit actually contains, what fourteen purchase-badged owners have said, and whether the 49.45 buy makes sense before or after you own the headset.
The Half Helmet Kit is Cardo model ACC00013, a 2.46 ounce mounting set with a 2-year manufacturer warranty. Its ladder sibling is the Pro and Edge kit we have covered separately, and the second-helmet kit is the box that carries the speakers this one leaves out. Our second-helmet kit review and Pro and Edge kit review cover both of those boxes owner by owner, and the intercom comparison table sorts the full field by price per rider.
What 49.45 buys on a kit with no speakers
The kit holds a multi-position adjustable clip, a flexible gooseneck microphone cable and an extra-long boom microphone, and it weighs 2.46 ounces. The spec table carries a waterproof row and a 2-year manufacturer warranty, both real terms for hardware that lives exposed on an open-face lid. There's no battery, no speaker, no radio and no electronics inside the box. That's why the table's 13 hour battery row and its Bluetooth rows are template furniture copied from a communicator listing.
Everything the kit leaves out is the point of its price. At 49.45 it undercuts its own 125.96 ladder sibling by 76.51, and the missing 76.51 is mostly the speakers: the covered second-helmet kit sells the audio plus microphone set at 99.95, and the speakers-only 45mm Audio Set lists at 98.95. One owner puts the total plainly, counting about another 100 spent on top of this kit before the setup makes sound.
So the honest frame is this: 49.45 buys half-helmet compatibility for a Packtalk unit you already own, and the sound comes from somewhere else, whether that is the audio kit your Edge shipped with, the covered second-helmet kit, a set of earbuds, or the speakers already mounted in a different helmet of yours. Wherever the speakers come from, a helmet gives a driver no enclosure, so bass depends on getting the speaker close to the ear rather than on the driver itself (Wikipedia).
The cradle the listing promises and the owners say is missing
The second bullet reads that the kit comes with a cradle and all required mounting gear, and a spec row repeats the claim under mounting hardware. Three owners contradict it. The July 2026 one-star is the bluntest: the description states the cradle is included, it is not, and what arrives is the boom mic, the mic cable and a spot where the cradle should sit, which leaves the kit, in the owner's words, pretty useless without one.
The October 2025 three-star says the same in calmer terms, no cradle included, buy it separately, and save yourself the time by ordering the complete setup instead. The most useful text is also the oldest, an April 2023 four-star that dates the change. The Packtalk Bold version of this kit included the cradle, its author writes, and the Edge version doesn't. The practical workaround is reusing the cradle from your own Edge box, or buying a second one so you're not swapping it between helmets every ride.
Read together, the record describes a listing that never caught up with a contents change. Nothing here says the kit is bad, but I'd order it only with a cradle plan in place, and check the box contents inside the return window.
The boom accounts disagree by year
The boom microphone is the part this kit exists for, and the record splits on it. A November 2023 owner calls it outstanding, says it stays where you put it, and credits it with pulling a puffy boom ball out of his wife's face while keeping wind and ambient noise isolated. A November 2025 two-star says the opposite: the boom will not hold position at riding speed and needs reinforcing.
Both can be true, because a gooseneck fatigues and clamp tension drifts with heat cycles, but the record doesn't say which account is the typical one. The rest of the install advice is more consistent. An April 2023 owner found the printed instructions show a five-eighths helmet rather than a half helmet, and he describes the install that actually works. Mount the main unit on the fiberglass shell, he says, and run the wires down to the kit on the leather ear flap so the microphone sits where it should. The same owner got two FM radio channels where a car radio in the same spot found more, worth knowing before anyone buys this kit for the radio.
The remaining texts are short and consistent. A 2025 owner fitted it to a Seer half helmet and called the fit and sound outstanding. Another recommends plain earbuds with a half helmet. One more reminds buyers to update the firmware on the Edge before judging the sound.
Who this kit is for, and who should skip it
This is a specialist part with a mainstream rank. It sits at number 5 in Powersports Helmet Communication, far above the Edge single at 273 and the 45mm Audio Set at 15,876, which says half-helmet riders are finding it in numbers.
Buy it if a Packtalk already sits in your garage and a half helmet or ski helmet waits for it, and if you own the cradle question by planning for the mic and clip to arrive alone. Skip it if you ride a full-face helmet, because the Pro and Edge kit serves that case with speakers included. Skip it too if you don't own a communicator yet, because a bare Edge single plus a complete kit is the order that ends with a working setup. The Edge single review carries the deep record behind that choice.
One warning has nothing to do with the kit itself: the listing shows only two left in stock. If this page sells out, the covered kit reviews are the places to watch for a replacement.
Common questions about the Half Helmet Kit
Does the kit include speakers?
No, and the bullet says so directly. Speakers come from the audio kit your Edge shipped with, the covered second-helmet kit, the 45mm Audio Set, or earbuds, and one owner counts about another 100 before the setup makes sound.
Does it come with a cradle?
The listing says yes and three owners say no, including one who dates the change to the switch from the Bold version to the Edge version. Plan on the cradle coming from your existing box.
Will it fit my helmet?
It's built for half helmets, ski helmets and other non-motorcycle lids with no ear cavity. A 2025 owner confirms a clean fit on a Seer half helmet.
Does the boom microphone stay put?
The record disagrees. A 2023 owner praises a boom that holds position and isolates wind, a 2025 owner says it will not hold at speed. Both are single accounts, and neither is typical by any measure the record offers.
Can I use it without owning a Packtalk unit?
No. The kit is mounting hardware and a microphone for an existing communicator. Without one there's nothing to mount, and no sound path at all.
