Quick take
- Humane's AI Pin is the cautionary tale this whole category is built around: $699 device, $24/month required subscription, daily returns outpacing daily sales by mid-2024, and a total of under 10,000 units ever sold before HP bought the software and patents for $116 million in February 2025 — the device business itself was shut down.
- Returned Pins couldn't even be resold: a T-Mobile limitation prevented reassigning a Pin's cellular ID, turning returns into e-waste.
- Limitless (formerly Rewind) was acquired by Meta in December 2025, which immediately halted new pendant sales — as of this piece, it's no longer a purchasable product.
- Bee, a $49.99 always-listening bracelet, was acquired by Amazon in July 2025 and folded into its Devices & Services division.
- Friend, a $129 necklace, spent over $1 million on a New York City subway ad campaign that got extensively vandalized with anti-AI graffiti — its founder called the backlash "artistically validating."
- Plaud Note/NotePin ($159) is the one product in this category with no acquisition or failure narrative attached, built around a narrower, less controversial job: meeting and conversation transcription.
Every AI wearable pendant sold in 2026 exists in the shadow of one very public failure. Humane's AI Pin promised to replace your phone; instead it became one of the fastest, most complete hardware collapses in recent tech history. Limitless, Bee, Friend, and Plaud all bet that a narrower promise — passive listening, not a screen, no forced subscription in some cases — would succeed where Humane's $699 gadget didn't. The twist nobody was quite predicting: by the time this piece was written, half of that "successor" lineup had already stopped being independent companies.
What actually happened to Humane
Humane's AI Pin launched at $699 with a required $24/month subscription. Internal data obtained by The Verge showed daily returns outpacing daily sales between May and August 2024 — roughly 10,000 units shipped, about 7,000 remained with customers, against roughly $9 million in lifetime sales and $1 million in returns. Because of a T-Mobile limitation preventing reassignment of a Pin's cellular ID, returned devices couldn't be resold or refurbished; they became e-waste.
Humane's original goal was 100,000 units in year one. It never got close. HP acquired the company's software platform, over 300 patents, and most of its staff for $116 million in February 2025 — down from a rumored $1 billion prior valuation, and a steep loss against the roughly $230 million Humane had raised. The device business itself was excluded from the deal and shut down: Pins went fully dead on February 28, 2025 at 3pm ET, with all cloud features killed, T-Mobile connectivity cut, and user data permanently deleted.
Limitless: acquired, no longer for sale
Limitless (formerly Rewind) was a clip-on pendant that recorded and transcribed in-person conversations into a searchable personal log — $99 for the free-tier hardware or $199 bundled with a Pro plan at $19/month. Marketed battery life was roughly 100 hours standby, though real continuous-recording life ran closer to 6–7 hours, about a workday, per multiple reviewer reports.
Meta announced its acquisition of Limitless on December 5, 2025 and halted new pendant sales immediately. Existing owners were promised free unlimited service through 2026, but as of this piece's publication, Limitless hardware is no longer purchasable new — which complicates any clean "four independent successors" framing of this category.
Bee: acquired, folded into Amazon
Bee is a $49.99 Fitbit-like bracelet (also available as an Apple Watch app) requiring a $19/month subscription for full features. TechCrunch and CNBC confirmed Amazon's acquisition in July 2025; terms were undisclosed. By January 2026, Amazon had folded Bee into its Devices & Services organization and added Voice Notes, real-time conversation processing the company describes as not storing raw audio, and email/calendar integration that auto-drafts messages from spoken instructions.
Bee's original privacy policy claimed audio isn't stored or used for AI training and is user-deletable, but reporting has flagged real uncertainty over whether that policy survives full Amazon integration — coverage specifically drew a parallel to Amazon's history of sharing Ring doorbell footage with law enforcement without owner authorization.
Friend: independent, and leaning into the backlash
Friend, a plastic AI necklace from 22-year-old founder Avi Schiffmann, launched at $129 with a single microphone and 15-hour battery; a second-generation version with a speaker later launched at double the price, $249. The company raised a $2.5 million seed round in July 2024 from investors including Perplexity CEO Aravind Srinivas and Solana co-founder Anatoly Yakovenko.
Friend's defining moment was its marketing, not its hardware: over $1 million spent on roughly 11,000 New York City subway ads in September 2025, the largest subway campaign of that year. The ads were extensively vandalized with anti-AI graffiti — slogans like "AI doesn't care if you live or die" and "surveillance capitalism" — and Schiffmann embraced the backlash publicly, doing a photoshoot in front of the vandalized ads and calling the reaction "artistically validating."
Plaud: the one without a crisis attached
Plaud's Note and NotePin devices, both $159 (with a Pro tier at $189 and combo bundles up to $318), are built around a narrower job than any of the other three: recording and transcribing meetings and conversations, with subscription tiers from $17.99/month up to $29.99/month for unlimited daily transcription. This research found no acquisition, shutdown, or major privacy controversy attached to Plaud specifically — it's the one product here with the clearest, least contested niche.
AI Pin
Under 10,000 units sold. Device business shut down Feb. 2025; software/patents sold to HP for $116M.
Limitless
Acquired Dec. 2025. New sales stopped immediately — no longer purchasable as an independent product.
Bee
Acquired Jul. 2025, folded into Devices & Services. Privacy policy continuity post-acquisition is unclear.
AI Necklace
$2.5M seed. Famous for a vandalized $1M+ NYC subway ad campaign the founder called "artistically validating."
The pattern: narrow jobs survive by getting absorbed
One trade-press analysis (Digital Applied) frames the pattern plainly: products trying to replace the smartphone outright — Humane's AI Pin, the Rabbit R1 — failed outright. Products doing one narrow job well, like passive transcription, survived mainly by getting absorbed into a much larger platform company rather than by succeeding as standalone hardware businesses. Limitless and Bee, the two closest analogues to Humane's original always-listening pitch, both got bought by trillion-dollar companies within six months of each other in 2025 — which is itself evidence the standalone-hardware model in this category hasn't proven durable, even where the underlying product works.
Friend remains independent, but appears to be succeeding on notoriety more than demonstrated retention or usage data — none was found in this research. Plaud, doing the narrowest and least controversial job of the four, is the only one with neither an acquisition nor a public failure story attached.
The legal backdrop every pendant in this category shares
Thirteen US states require all-party or two-party consent to record a conversation, directly implicating any always-listening wearable. In February 2026, California state senator Eloise Gómez Reyes introduced SB 1130, the Wearable Device Privacy Protection Act, which would criminalize secret recording via wearables inside businesses — a direct legislative response to this exact product category.

Common questions
Can I still buy a Humane AI Pin?
No. The device business shut down entirely on February 28, 2025; only the software and patents were sold, to HP.
Can I still buy a Limitless pendant?
Not as a new purchase. Meta acquired Limitless in December 2025 and halted new sales immediately, though existing owners retain service through 2026.
Is Bee still an independent company?
No. Amazon acquired Bee in July 2025 and folded it into its Devices & Services division by January 2026.
Why did Friend's ad campaign get so much attention?
It spent over $1 million on roughly 11,000 New York City subway ads that were extensively vandalized with anti-AI graffiti — the founder publicly embraced the backlash rather than distancing from it.
Which of these has avoided controversy?
Plaud, whose Note and NotePin devices focus narrowly on meeting/conversation transcription with no acquisition or major privacy incident found in this research.
The clean version of this story — four scrappy startups learning from Humane's mistakes — isn't quite what happened. Two of the four "successors" already stopped being independent companies, absorbed by Meta and Amazon within six months of each other, which is its own quiet admission that standalone hardware in this category is hard to sustain even when the product works. Friend is winning attention through controversy it's actively courting, not demonstrated usage. Plaud, doing the smallest and least dramatic job of the bunch, is the only one that's just... working, without a crisis attached. The lesson from Humane wasn't "make it cheaper" or "cut the screen" — it was "pick a narrow enough job that a bigger company wants to buy you before you run out of money."
