Amazon introduced two new Bee AI devices on October 15, 2026: the $74.99 Bee Frontier wearable, available now, and the $99.99 Bee Eclipse magnetic phone attachment, which Amazon says will arrive soon with no confirmed release date.
It's the first hardware update since Amazon bought the startup in July 2025, and the Bee Frontier vs Bee Eclipse choice comes down to one practical question: something worn on the body, or something attached to the back of a phone.
Both devices run the same underlying Bee software, turning spoken conversations into transcripts, summaries, and to-do lists. The Verge describes form factor as the main difference between them: Frontier straps on like a fitness tracker or clips onto clothing, while Eclipse is designed for more phone-centric use.
Battery life splits sharply too, with Frontier rated for up to seven days and Eclipse rated for more than 21 days.
For readers comparing the Amazon Bee Frontier and Bee Eclipse, the main distinction is whether the Amazon Bee AI recorder stays on your body or rides on your phone. Only one of the two can actually be ordered today. The rest of this comparison lays out what's confirmed, what's still unproven, and what it costs to unlock the features Amazon is leading with.
Bee Frontier vs Bee Eclipse differences: availability and form factor
The Bee Frontier AI wearable is the successor to the original Bee Pioneer. It's sold in three colors, Onyx, Lavender, and Sage, with a silicone wristband and an included clip for attaching it to clothing.
Frontier also carries an IP67 water-resistance rating and has dual microphones with noise filtering.
The Bee Eclipse takes a different shape entirely: a credit-card-sized device that magnetically attaches to the back of a phone. It comes in Silver, Midnight, Honey, and Blush and measures 4.6mm thick.
Bee's current product page also resolves one specification that wasn't included in Amazon's launch announcement: Eclipse has four microphones, compared with Frontier's two. It includes a metal ring accessory and is MagSafe compatible.
Availability is where the two devices diverge most for anyone ready to buy right now.
Amazon currently lists Frontier as available for $74.99 and Eclipse as "available soon" starting at $99.99. No Eclipse release date has been announced.
The key differences break down like this:
Bee Frontier: $74.99, available now, wrist-worn or clip-on design, dual microphones, IP67 water resistance, USB-C charging, and up to seven days of battery life.
Bee Eclipse: $99.99, coming soon, magnetic phone attachment, four microphones, MagSafe compatibility, USB-C charging, and more than 21 days of battery life.
Both: Conversation processing and summaries, 14 days of history on the free tier, support for more than 40 languages, and an optional Bee Pro subscription.
That makes Frontier the only real buying choice today. Eclipse is still a product to wait for rather than something shoppers can reliably order.
Battery life, privacy, and microphones: Bee Frontier vs Bee Eclipse specs
Frontier's confirmed specs are straightforward: up to seven days or 160 hours of battery life, USB-C charging, IP67 resistance, and dual microphones with noise filtering that Bee says improves transcription in noisy environments.
Eclipse's headline advantage is battery life. Bee rates it for more than 21 days on a charge, or roughly three times Frontier's maximum. Its larger body also accommodates four microphones rather than two.
Eclipse charges through USB-C as well, so charging method is no longer an open question.
Both devices share similar physical controls. A single press starts and stops processing, and an LED indicates when the device is active. Long-pressing the button creates a voice note, while a double press bookmarks a moment for easier retrieval later.
Frontier can also be configured to stop automatically after a chosen period of silence.
Privacy architecture is shared across both products under what Amazon calls Bee Private Compute. Amazon says audio is processed in real time and then discarded rather than stored. Transcripts and other generated information are encrypted with keys created and controlled by the user's device.
Amazon also says Bee verifies that a server is running approved software before protected information is released for processing and that Amazon doesn't hold a master key capable of decrypting a user's private Bee content.
Those claims have received outside scrutiny. Security firm Trail of Bits conducted an eight-week review of Bee Private Compute in September 2026, examining its mobile apps, servers, and related infrastructure.
The review initially identified 21 issues, including seven rated high severity and seven rated medium. Amazon subsequently worked through fixes during the review process, so the audit provides substantially more technical evidence than a company privacy promise alone while also showing that the architecture had meaningful security issues to address.
One detail also needs careful wording: Bee isn't passively recording around the clock. The user activates and deactivates processing with the physical button, and the LED indicates when it's active. Amazon also allows Frontier to stop after a selected period of silence.
What's free vs what needs the $11.99 Bee Pro subscription
Buying either piece of hardware doesn't unlock Amazon's full pitch for Bee.
The free tier includes conversation processing, conversation summaries, and 14 days of history.
Bee Pro expands that to unlimited history and adds daily summaries, Bee for Desktop, conversation templates, suggested to-dos, deeper insights, and integrations with Outlook, Gmail, Calendar, Photos, Health, Alexa, and Amazon.com.
Bee Pro costs $11.99 per month or $99.99 per year. Every new Bee customer gets 30 days of Pro free.
That annual option matters to the cost calculation. Paying monthly for 12 months would cost $143.88, but the $99.99 annual subscription brings a full year of Pro below the purchase price of Eclipse and only $25 above Frontier's hardware price.
Amazon's Alexa and shopping integrations also sit behind Bee Pro rather than the free tier.
Connecting Bee with Alexa+ lets users ask compatible Echo devices for summaries and to-dos. The Amazon.com integration can use information users choose to share from Bee to generate personalized shopping recommendations based on things mentioned in conversations.
Those integrations are optional. Amazon says connecting an Amazon account for sign-in alone doesn't give Amazon access to private Bee data.
What's still unproven before you buy
The available reporting doesn't provide comprehensive independent testing of Frontier's real-world battery life, Eclipse's 21-day-plus battery claim, or transcription accuracy across both devices.
Amazon says Frontier's dual microphones and noise filtering can produce accurate transcription in noisy environments, but that's a manufacturer performance claim rather than an independent benchmark.
The same caution applies to Eclipse's battery life until reviewers test shipping hardware.
Eclipse does have a feature Frontier doesn't: processing both sides of phone calls. Amazon says users are prompted to obtain permission from call participants each time a recording starts.
That product safeguard doesn't settle the legal question. Recording and consent requirements vary by jurisdiction, and using an ambient recorder for in-person conversations can raise similar issues.
The security picture is more nuanced than either "Amazon says it's private" or "it hasn't been tested." Bee Private Compute has undergone an independent security review, and Amazon has published technical details about its use of AWS Nitro infrastructure, device-controlled encryption keys, and server verification.
At the same time, the Trail of Bits assessment found multiple security issues during its review. Buyers considering Bee specifically because of its privacy architecture should read that audit alongside Amazon's claims rather than treating either one as the whole picture.
What to do now
Frontier is the Bee to buy if you need one now. At $74.99, it offers IP67 resistance, two microphones, USB-C charging, an included wristband and clip, and up to seven days of claimed battery life.
It's also the better fit if the point is ambient capture throughout a normal day, since it can stay on a wrist or clothing instead of occupying the back of a phone.
Eclipse makes more sense on paper for phone-heavy use. Its four microphones, ability to process both sides of phone calls, magnetic design, and more than 21 days of claimed battery life give it clear hardware advantages for that role.
But it isn't actually available yet. Buyers interested in Eclipse should wait for Amazon to announce availability and for independent reviews of shipping hardware rather than treating its claimed battery life and recording performance as established.
Anyone considering Bee Pro should also factor in the recurring cost. Start with the included 30-day trial and see whether unlimited history, suggested to-dos, desktop access, Alexa, Amazon shopping, and third-party integrations are useful enough to justify $11.99 per month or $99.99 per year.
For most buyers choosing today, Frontier wins by default because it's the only one on sale. Eclipse is the more specialized option, with substantially longer claimed battery life and stronger phone-call hardware, but it can't win a buying comparison until there's actually a confirmed date when you can buy it.
