THETREE sells the X2 two ways. One listing carries a single unit at 29.99, and a second page boxes two of them for 59.99. Both are 2-way Bluetooth intercoms, well below the mesh packs the brand sells under its X10 name, and both pages print the same rating pool, so a buyer is reading one record through two doors.
A rider looking at either page wants something simple: a cheap way to talk to one other helmet, or to hear music and calls clearly, without paying intercom-brand prices. The single rung covers half of that job. The second half arrives whenever the second unit does, and the two pages price that choice in an odd way this review works through.
The record under both listings has a shape worth knowing before you order. Nineteen ratings at 4.6 with nothing below three stars, and eleven written texts, ten of them carrying purchase badges, which is more proof of real buyers than most budget listings manage. What the texts almost never contain is a ride report.
This review works from the single-rung listing, scraped signed in on October 30 through both review sorts, with every text matched against the page's claims. What follows is what the record actually proves, the claims it never tests, the quirk two owners hit, and the math between one unit and two.
The verdict up front. The THETREE X2 single rung sells one complete helmet kit at 29.99, which our table prices at 15.00 per rider against the two-helmet claim, rank 69 of the 210 intercoms we track. The exact live position sits on the intercom comparison table because it moves with every price refresh.
The honest per-helmet figure is the full 29.99, because the second rider of the 2-way pair needs a unit too. The double pack rung sells both halves for 59.99, which works out to 30.00 a helmet, about a penny over buying two singles. The pair buys no discount, only convenience, and the single rung is where the family's best number lives.
A record of first impressions, not rides
The buyer texts read like install notes, and that's the single most important thing about them.
The most recent owner reports a quick drive at low speeds with good sound and a highway test still to come. Another, whose review carries a video, admits no phone call has been taken in it yet while recommending it anyway. A third wrote that they haven't been on the road, and a fourth that they haven't tried to pair with anyone.
None of that makes the 4.6 wrong. It makes it a grade for unboxing, install, and speaker quality rather than for the intercom job the listing leads with. Two owners have linked the X2 to Sena units, one pairing it with a 50S for a partner's spare helmet and reporting the process not hard, the other connecting to a newer Sena with no issues, so cross-brand phone-and-audio linking has real witnesses.
The Sena comparison is also the best calibration on the page. That owner, whose text tops the helpful sort, calls the X2 not as good as the Sena but very good at about a tenth of the money, with speakers loud enough for the price.
What no text contains is a conversation between two X2 units. Nobody has reported a range test, a group link, or even a second THETREE on the ride. One owner handed the headset to a family member after an injury and passed along praise for the clarity and the intercom feature, though that account is secondhand.
The 2-way claim you're paying for is the part of the X2 the record has not exercised.
What 29.99 buys in the box
The kit is complete for one helmet. It includes the clamp mount, a set of 40mm speakers that measure just 9mm thick so they fit shallow pockets, both microphone styles, a button mic and a boom, and a charging cable. The whole unit weighs 3.2 ounces.
One buyer confirms the earphone and multiple mic options arrive as described, which matters because boom mics suit open-face helmets and button mics suit full-face ones.
The battery figures decode plausibly for a unit this small. A 700mAh cell claiming 18 hours of talk time implies an average draw of about 39 milliamps, and the 300-hour standby claim works out to about twelve and a half days.
A full charge takes about 2 hours over USB-C. One details row contradicts the bullet here, calling the hardware interface Micro USB Type B while the bullet promises Type-C, a form-filling slip that the cable in the box settles.
The sealing is IP67, which means the X2 is rated dust resistant and able to survive immersion a meter deep in fresh water for 30 minutes (Wikipedia, IP code).
For rain and road spray that's stronger paperwork than the budget band usually offers. The warranty row says one year, and the listing carries a Brazilian ANATEL certification number, an oddity that at least shows the hardware has passed through a national telecom process.
The range claim, and the row that disagrees with it
The first bullet claims 800 to 1000 meters of 2-way intercom in open areas. Further down, the details table prints a Bluetooth Range of 100 meters. The two numbers describe different radios: the 100-meter row is the ordinary phone link, whose reach depends on the radio class rather than the intercom path (Wikipedia, Bluetooth), so the pair isn't the contradiction it looks like.
The intercom claim itself is the problem, because the record contains no range report at all. No owner has measured anything, and several haven't ridden with a partner yet. Treat 800 to 1000 meters as a paper number from a listing whose smaller claims have checked out, and plan around visual range until a buyer proves otherwise.
Two owners hit the same language quirk
Two of the eleven texts, written two days apart by different buyers, describe the same fault. One reports not liking the Chinese voice the X2 plays at power on and off. The other, writing in Spanish, says the units switch into Chinese on their own and that getting them back to English or Spanish is difficult.
Neither text offers a fix, and nothing on the listing page acknowledges the behavior. It's a small fault next to sound quality and price, but it's the only complaint the record repeats, and a buyer who rides in another language should know the voice prompts may need wrestling.
Buy one, or buy the double pack
The decision this page forces is about the second helmet. For one rider who wants music, calls, and maybe a link to a Sena-owning partner, the single rung at 29.99 is the cheap way in, and the record's install-and-sound praise says the hardware works as described. The risk you carry is 29.99, and the parts of the claim nobody has tested.
For two helmets, buy the double pack rung instead, and not for the discount, because there isn't one. One buyer ordered this single listing believing the box held everything for two helmets, reading the X2 writing on the packaging as a promise of a pair, and received one headset.
The double rung exists precisely so nobody repeats that order. It prices at 30.00 a helmet against 29.99 for the single, and our table ranks it lower for identical hardware because the per-rider metric divides each page's price by the same two-rider claim.
Riders who want group mesh from the same brand should read our THETREE X10 single review, a 39.99 mesh unit with its own unproven group claim and a longer written record.
Frequently asked questions
Does the single pack include two headsets?
No. One unit. The variant ladder lists an X2-Single Pack and an X2-Double Pack as the only two rungs, this page is the single at 29.99, and the details table says Number of Items 1. One buyer has made exactly that mistake, so read the rung name before ordering.
Is the 800-1000m range claim real?
Nobody in the record has tested it. No text reports an intercom conversation between two X2 units, let alone a measured distance. The 100-meter row in the details table describes the phone link, not the intercom path.
Can the X2 talk to a Sena or other brands?
Two owners have linked it to Sena units, one a 50S, and both report the connection working. Cross-brand linking with a Sena is likely rather than proven across every brand, and no text describes a link to any other make.
How does the double pack change the math?
The double rung costs 59.99 for two complete units, which is 30.00 a helmet against 29.99 for two singles. It buys certainty about what arrives in the box, not savings, and our double-pack review covers the pair decision in full.
