RayNeo X3 Pro Review: Full-Color AR Glasses With a Battery Measured in Minutes

This is the section that decides the purchase. The cell is about the size you would find in camera glasses without any display at all, and here it feeds two projectors and an Android computer. RayNeo's current page gives no runtime. Its FAQ says battery life "varies significantly with usage" and names navigation, camera recording, AI processing, wireless connections and apps as the heavy users.

The reviews fill in what that means. Tom's Hardware reported that RayNeo had claimed up to five hours, and that in general use it never got more than an hour. Opening Google Maps at half charge brought a low-battery warning within ten minutes, and two songs took a few percent off. That was a pre-release unit on pre-release software, so treat it as a warning, not a final figure. Notebookcheck, reviewing later, got around 30 minutes of continuous video recording and had to recharge three times to film one outing.

Charging is quick, about 38 minutes to full over USB-C. The problem is where you do it. Notebookcheck points out that the carrying case has no battery, so there is no topping up in a pocket the way Ray-Ban Meta owners do. In practice that means a power bank and a cable, and short sessions: a translated conversation, a route through an unfamiliar station, a few photos.

The display is where the X3 Pro leads. Each lens has its own micro-LED projector and waveguide, so both eyes see the same image, where the Meta Ray-Ban Display puts a screen in one lens only. RayNeo rates it at 3,500 nits on average and 6,000 at peak, with a 30-degree field of view that it compares to a 43-inch screen two meters away. The resolution is modest at 640 by 480.

All three reviewers found it readable. Tom's Hardware called the waveguides bright and sharp with good color and bright enough for outdoor use, and Tom's Guide found them visible in bright surroundings. Notebookcheck adds a limit: there is no clip-on sunshade, so harsh sunlight is harder. Nobody has published a brightness measurement, so the nit figures are RayNeo's.

The glasses run RayNeo AIOS, an Android-based system with Gemini Live as the assistant. You long-press the left temple and ask about what the cameras see. Tom's Guide used it to plan a dinner from the contents of a fridge. RayNeo also lists real-time translation in 14 languages, heads-up turn-by-turn navigation through Google Maps, meeting transcription, a teleprompter and a to-do list.

The weak points are the joins between them. Tom's Guide found Gemini could not yet hand a request to the Maps app, and Tom's Hardware found that the assistant pointed it to navigation apps instead of starting a route. Third-party apps such as TikTok, Instagram and WhatsApp are available, but Notebookcheck found sideloading more apps needs developer tools. It also found that an iPhone gets fewer notifications than an Android phone.

A phone is needed for setup through the RayNeo AR app and helps with a hotspot away from Wi-Fi. RayNeo's product page and FAQ mention no subscription for the glasses' own features.

At 76 g the X3 Pro is light for AR glasses. Tom's Guide found it comfortable all day thanks to the weight distribution and cushioned nose pads, and Tom's Hardware found it not heavy on the face. Both were less kind about the looks: thick temples, projector bulges at the hinges and two cameras in the bridge, in mostly plastic that Tom's Hardware thought cheap for the price.

Prescription wearers can order custom inserts from RayNeo's partner Lensology, at extra cost. Our guide to prescription lenses for Rokid's glasses shows how that insert route typically works. A camera light on the front signals recording, which Notebookcheck sees as a necessary cue for people around you.
