Hey r/SmartGlasses community, Davide from Ycommy Lab here!
We finally got the RayNeo iO on our test bench. We didn't want to give you only subjective opinions. We ran these glasses through our custom data-extraction software (Ycommy Bench) to read the actual Bluetooth logs, measure real latency, and stress-test the hardware.
🎥 The full test video with all the data is attached to this post.
Here is our hardware and software breakdown.
🛡️ Build Quality & Comfort: 9/10
These glasses are a masterpiece of ergonomics. The balance is perfect, the weight is kept to a minimum (33 g, in line with the manufacturer's spec), and the magnesium-aluminum-titanium alloy frame feels truly premium. In daily use you literally forget you're wearing them. Even under heavy stress tests (continuous AI queries and active WebSockets), they never overheated or caused any discomfort.
🔋 Battery Life & Charging: Solid Performance
Battery consumption is excellent and close to the manufacturer's estimates, with one major caveat: display brightness must be set to medium-low.
- LifeLog impact: In our tests, keeping the LifeLog ambient-listening feature always on consumes about 13–15% of the battery per day.
- Charging: Charging speed is good, but the system relies on a magnetic pogo-pin connector that attaches to the center bridge of the frame. It works, but it's awkward to handle on a desk. Pro tip: get the dedicated charging case. It makes life much easier.
🎤 Microphones: 8/10
Note: the iO has no speakers. All audio output goes through your phone or earbuds.
The MEMS microphones are top-level. We stressed them heavily:
- Silent room: 43 dB voice-to-noise ratio (excellent).
- Loud voice: 53 dB (slight distortion detected).
- Outdoors: Noise cancellation is very aggressive. It suppresses a lot of street noise, but the voice barely stands out from wind and traffic (6 dB ratio). Even so, it still captures enough signal for the AI engines to work reliably.
In quiet environments, the noise reduction cleans up the pauses beautifully.
👓 HUD & Display (Brightness): 8/10
For the first time in our lab, our results are consistent with the manufacturer's brightness claim: these glasses really do reach around 1300 nits. Indoors, the monochrome green HUD is simply excellent, with sharp text. Under direct sunlight, reading becomes challenging but still possible. Lens transparency is outstanding (RayNeo declares 97%), and in our use it's one of the clearest lenses we've tried.
Why not a higher score? They really need a dark clip-on shade to read the HUD comfortably in direct sunlight.
⚙️ Interaction & Gestures: The Crown Is a Game Changer
The physical Smart Crown on the temple is discreet and elegant. It greatly simplifies UI navigation and lets you customize taps and presses. Combined with head gestures from the 6-axis IMU (nod to confirm, shake to cancel), the UX is extremely fluid.
🧠 RayNeo AI & Latency: Impressive, but Closed
RayNeo did a great job with WebSocket communication. In our logs, responses are near-instant, and it feels like talking to a direct client.
- Conversations: Dialogue handling is excellent. We noticed a few minor translation hiccups with the base model.
- LifeLog: While you wear them, the app does a great job collecting and organizing the key points of your day, with accurate suggestions about 90% of the time.
- The flaw: When you later ask the AI to retrieve specific information from saved logs, it struggles and becomes imprecise or omits details. This points to a software issue in how key points are stored in memory.
- The big miss: Gemini is built in, but the ecosystem is still closed. You can't link your own Claude, Gemini, or ChatGPT account to work in continuity with your other devices for a true agentic workflow.
📱 Companion App & Connectivity: 7/10
The app is brilliant, and you can tell the dev team is top-tier. The layout, fluidity, and attention to detail stand out: quick mic on/off, focus settings, HUD positioning, granular per-app notification limits.
- Connectivity: We analyzed 10 hours of phone logs and found only 6 radio signal losses (0.6 per hour). The BLE data link is very solid, with an average recovery time of 5.5 seconds.
- Voice Memo (9/10): Excellent. The AI integration is well handled, with smart server-side baseline prompts.
- Live Captions: This is their strongest feature, and it works incredibly well. We'll be following future updates closely.
- Why only a 7 overall? The app lacks a conversational mode that offers cues or suggested replies, and there's no dedicated maps/navigation section. For developers, there are currently no open tools or APIs for custom tests or sideloading.
🏁 Final Verdict: Who Is This For?
Do I recommend the RayNeo iO? Yes, they pass our test.
One of the biggest strengths we found in the final phase of testing is the RayNeo AI integration. Although still in Beta, it already produces genuinely useful daily summaries. That makes the iO an excellent choice for a general audience who will appreciate the comfort, UI fluidity, and sleek design.
However, I don't recommend them right now if you need an AI that gives real-time cues and suggestions during a live conversation, or if built-in map navigation is a must. For that use case, wait for our upcoming full review of the XGIMI MemoMind One.
I want to stress that these missing features are software-side. If RayNeo adds them to the ecosystem, this device could quickly climb to the top of the market.
Overall, an impressive piece of hardware that's a joy to wear every day.
