What Are the Best Smart Glasses With an AI Assistant?

A voice AI assistant needs a microphone to function at all, and that single requirement separates true AI glasses from display-only or camera-only models regardless of how they’re marketed. Two RayNeo models clear that bar: the RayNeo X3 Pro, running on Google Gemini and available now, and the newly announced RayNeo iO, arriving September 4, 2026, built around letting you pick between several AI models instead of just one.

The Dividing Line: A Microphone, Not a Display

A lot of products marketed as “smart glasses” or “AI glasses” have a camera, a display, or both, but no way to actually hear you talk. Without a microphone, there’s no assistant to wake up in the first place, no matter what’s printed on the box.

RayNeo’s Air series (Air 2s, Air 3s, Air 3s Pro, Air 4 Pro) falls into that category. None of their official spec pages list a built-in microphone. They connect over a wired USB-C cable and are built around mirroring a phone, laptop, or console screen for video and gaming, not around talking to an assistant. If an AI assistant is the feature you’re shopping for, the Air series simply isn’t a candidate, regardless of price or display quality.

RayNeo X3 Pro: A Wake Word Into Google Gemini

The X3 Pro is a standalone AI and AR device, meaning it doesn’t rely on a phone tethered nearby to run its core hardware.

• Chipset: Qualcomm Snapdragon AR1
• Connectivity: Its own Wi-Fi radio
• Microphone array: 3-microphone beamforming, designed to isolate your voice from background noise
• AI model: Google Gemini 2.5, described by RayNeo as “always-on”

That always-on design is what lets the wake word work at all. Saying “Hey RayNeo” activates the assistant without touching the frame first, the same continuous-listening approach a smart speaker or a phone’s built-in assistant uses. In practice, that means you can ask a question mid-walk or glance at a translation mid-conversation without reaching for your phone.

Not everything on the X3 Pro is voice-triggered, though. Navigating menus and switching modes relies on 5-way touch input built into the temple, with Apple Watch pairing available as a secondary, software-dependent control option. The wake word covers starting a query or a translation; it doesn’t cover full menu control.

Battery life depends heavily on what you’re actually doing with the glasses, so RayNeo publishes separate figures for each use case rather than a single number.

• Continuous video recording: Roughly 30 to 36 minutes
• Mixed everyday use (switching between display, camera, and assistant): About 1 to 2 hours
• Music playback alone: Around 3 hours
• Audio-only recording: Up to about 5 hours

The always-on wake word isn’t the main drain here; it’s the display, camera, and cloud-based Gemini queries that pull the battery down fastest. If you’re planning to lean on the assistant throughout a full workday, plan around the video-recording figure rather than assuming an all-day single charge.

As of this writing (August 29, 2026), RayNeo’s product page lists the X3 Pro at a $1,099 sale price, down from a $1,299 list price, as part of a limited-time promotion. Confirm the live price on the product page, since promotional pricing changes.

RayNeo’s product and support pages don’t list a separate subscription or usage cap for the Gemini-based features described below. General Q&A, translation, and meeting notes are included with the purchase price rather than gated behind a recurring fee. That’s different from iO, covered later in this guide, where RayNeo’s own support documentation points to a paid membership layer for some AI model options.

Voice Tasks It Handles: Q&A, Translation, and Meeting Notes

Once the wake word triggers the assistant, the X3 Pro handles a specific set of tasks:

• General Q&A. You ask Gemini something, and the answer appears as text in the display, “directly in your field of view.” RayNeo’s materials don’t state whether general answers are also spoken aloud through the speakers.
• Real-time translation. RayNeo’s launch materials cite around 14 supported languages, including Chinese, English, German, French, Spanish, Japanese, and Korean. Translated speech is confirmed to include synchronized audio alongside the on-screen caption, so this is the one feature you can rely on hearing rather than just reading.
• Meeting Notes and transcription. Saying “Hey RayNeo” can start recording and later produce a summary with key points pulled out, described in RayNeo’s launch materials as an “Always-There AI Companion and Secretary.” That framing is really describing a record-then-summarize workflow: you talk, it records, and you get a condensed write-up afterward rather than live meeting minutes scrolling by.
• Task reminders, memos, and schedules. RayNeo’s own product materials list these as part of the same AI Productivity feature set, surfaced directly in the display rather than through a separate app you’d have to open.

Multi-turn conversation, asking a follow-up question without repeating “Hey RayNeo”, isn’t detailed in RayNeo’s published materials. Gemini’s underlying model is built for that kind of context-holding dialogue, but RayNeo hasn’t spelled out whether the glasses carry that context between exchanges. Test this on the device directly if a natural back-and-forth matters for how you’d use it.

Connectivity works the way most standalone AI hardware does. Basic functions like the camera and simple display readouts work without any connection. Gemini’s actual reasoning and real-time translation need an internet connection, either the glasses’ own Wi-Fi or a phone’s hotspot. The wake word itself runs locally, so the microphone still picks up “Hey RayNeo” with no network at all; it just can’t answer anything until a connection comes back.

Does This Replace Siri or Google Assistant on Your Phone?

The X3 Pro runs as a standalone assistant layer built directly into the glasses, not as a bridge to your phone’s existing assistant. It has its own Android-based operating system, its own chipset, and its own radios, so saying “Hey RayNeo” triggers RayNeo’s Gemini integration directly rather than routing through Siri or your phone’s Google Assistant app. Based on that architecture, the glasses’ assistant and your phone’s assistant work as two independent systems rather than one standing in for the other.

That means two assistants end up coexisting: whatever’s already on your phone, and a second, independent one built into the glasses with its own wake word and its own model behind it. Your phone still plays a supporting role, mainly for setup, firmware updates, and supplying a data connection when the glasses’ own Wi-Fi isn’t available, but the assistant interaction itself doesn’t pass through your phone’s native assistant at any point.

The practical effect is that reminders, memos, and calendar-style items you create by talking to the glasses live in RayNeo’s own AI Productivity feature set rather than syncing automatically into whatever calendar or reminders app your phone’s assistant already uses. Treat the two as complementary: lean on your phone’s assistant for anything tied to your phone’s own apps, and use the glasses’ wake word for hands-free answers, translation, or notes you’d rather not stop to pull your phone out for.

RayNeo iO: A Choice of AI Models in a Lighter Frame

RayNeo announced iO on August 21, 2026, with retail availability starting September 4, 2026. It’s a lighter, display-plus-assistant device built around reducing how often you need to pull out your phone for everyday tasks, rather than around a camera. Published specs don’t list a camera at all.

A few things distinguish iO’s approach to the assistant itself:

• Physical control, not just voice or touch. iO uses a Smart Crown, a small physical dial built into the temple, alongside head movements and the companion app, as ways to interact with the display. That’s a different control layout from the X3 Pro’s touch panel, closer to turning a dial than tapping a frame.
• A Personal Dashboard. The main interface surfaces time, weather, battery level, calendar, to-do items, stock prices, mail, and world clock directly in the lens. RayNeo’s page doesn’t specify which calendar or mail providers connect through the companion app, so check the app’s account-linking screen for your own provider before assuming it works with a specific work calendar.
• Live Captions & Translation. RayNeo’s support documentation confirms real-time, in-lens captions covering 40 languages, built around a single speaker talking to you directly, with your own voice filtered out.
• Voice Memo for meetings. Two recording modes, Wide Spectrum for meetings and multi-person conversations, and Voice Isolation for interviews and one-on-one talks, with automatic speaker separation you can rename in the transcript afterward, and a generated summary covering key conclusions and to-do items. RayNeo’s support page confirms this covers 100+ languages for transcription.
• A choice of AI models. RayNeo’s launch materials name four options selectable through the companion app: Gemini, ChatGPT, Claude, and DeepSeek. RayNeo’s support page, under a section titled “AI Models & Membership,” states that “Multiple mainstream AI models” are available and that “Subscribing to membership unlocks additional advanced AI models,” which points toward at least some of these four options sitting behind a paid membership rather than all four being included free. RayNeo hasn’t published the membership cost yet, so budgeting for a possible ongoing fee makes sense if model choice is the main reason you’re considering iO.

RayNeo’s own materials put iO’s weight at about 33 to 34 grams (34g per RayNeo’s blog post on the device, about 33g in the original August 21 launch materials), noticeably lighter than the X3 Pro’s 76 grams, which matters if all-day wear for something you’d keep on through back-to-back meetings is a priority.

Since iO hasn’t launched, its wake word (if it has one distinct from a button press), multi-turn conversation handling, and offline behavior aren’t documented anywhere yet. As of this writing, RayNeo’s iO page shows an early-bird promo code rather than a fixed retail price. RayNeo’s official launch announcement cites $479, with a charging-case bundle around $529; expect the product page to reflect that standing price once it updates for the September 4 launch.

Specs reflect RayNeo’s official product and launch pages as of August 29, 2026. Pricing and iO’s pre-launch specs are subject to change once iO ships.

Which Model Fits Your Situation

If you want something you can buy and use today: the X3 Pro is the only option; iO hasn’t launched yet.

If choosing between AI models matters to you, or you specifically want a lighter frame for long stretches of wear: iO is built around that, but budget for a likely membership cost for some model options and treat its pre-launch specs as subject to change at ship.

If group meetings with multiple speakers are your main use case: iO’s confirmed automatic speaker separation is a documented advantage over the X3 Pro, whose Meeting Notes feature doesn’t document that level of detail.

If a visual record (a whiteboard, a slide, a street scene) matters alongside audio: the X3 Pro’s dual-camera setup covers that; iO’s published specs don’t include a camera.

If you just want a bigger screen for video or gaming and don’t care about talking to an assistant at all: the Air series is built for that instead, at a lower price point, but it has no microphone and no voice assistant of any kind.
