A 25-gram AI glasses: how many steps from unboxing to working translation

I spent the weekend tinkering with this lightweight AI+AR glasses I have, and hit quite a few pitfalls. This post lays out the process clearly from unboxing to actually getting a feature running—follow it and you'll take fewer detours.

First, let me be clear about what this thing is. This set from Mojie Technology is called a lightweight fashion AI+AR glasses solution, and the key word is "solution." It's aimed at device manufacturers, providing a module plus design, not a finished product you can buy and take home. The whole device weighs under 25 grams, and the front frame is swappable. So the app and menu names on the pair you have may differ from mine, but the overall flow is the same.

The feature I picked is real-time translation. The reason is simple: among current AI glasses, this is the scenario that least depends on display area and most quickly verifies whether it's worth it. The AI assistant, navigation, and teleprompter mentioned in the materials are the same idea—get one running first, and the rest is just switching modes.

Step one, charge and power on. There's a Type-C port at the end of the temple; charge for twenty minutes first. The power button is usually on the right temple near the hinge; long-press for about three seconds, and the indicator light on the inside of the temple will come on. This is easy to misjudge. If you press for two seconds and release with no response, it's probably not long enough—just hold for a full three seconds.

Step two, install the app and pair. Install the companion app on your phone; the first time you open it you need to log in. After logging in, there's a + in the top right of the home page; tap it and choose Add glasses. The app will scan the code on the inside of the temple, or you can manually select the model from the list. Phone Bluetooth must be turned on in advance. When you see "Connected" on the interface, pairing is done.

Step three, swap the front frame. This is the most special part of this solution—the front frame is magnetic or clip-on, and you can swap it in seconds. Wear the dark frame for meetings, switch to the clear frame when going out—no need to buy two pairs. But after swapping you must redo calibration once.

Step four, calibration. Put on the glasses and follow the prompts to stare at several points that appear in sequence on the screen, or fine-tune the nose pad height so the display area falls in the upper part of your field of view. This step takes five minutes and saves you a lot of trouble later.

Step five, enter translation mode. On the app's Functions page, select Translation, and set the language pair, e.g., Chinese-English. The microphone on the temple picks up sound, and when the other person speaks, subtitles float in the upper right of your field of view. When you speak, just speak normally—no need to lean in.

Step six, real test. Find a quiet place and have someone read a passage from a meter away. Subtitle delay is around one second, and short sentences basically keep up.

A few pitfalls I hit. If you don't recalibrate after swapping the front frame, subtitles drift to the edge of your field of view, and after ten minutes you get dizzy—I fell into this on day one. Bluetooth is connected but microphone permission isn't granted, so speaking gets no response at all; you have to go into phone settings and enable it separately. In noisy environments the recognition rate drops badly—basically unusable in a café, but okay in a quiet meeting room. Also the nose pad: if it's not adjusted well, 25 grams still feels heavy—light weight doesn't mean it's not tiring to wear.

Step	Approximate time	Most likely to get stuck
Charge and power on	2 minutes	Long-press not long enough, misjudged as no battery
Pairing	3 to 5 minutes	Bluetooth and microphone permissions must be granted separately
Swap front frame and calibrate	5 minutes	Not recalibrating after swapping
Get translation running	1 minute	Ambient noise too loud

On the plus side, lightness is the one parameter of these glasses that software can't catch up on—25 grams worn all day leaves no mark on the bridge of the nose, a real difference compared with the 52-gram model mentioned in the materials; the front frame is swappable, saving the cost of buying two pairs; the onboarding bar is low—from pairing to usable in under ten minutes. The downsides, straight up: the display area is small, long sentences don't fit; the battery is stuffed in the temple, and battery life and weight are inherently a seesaw; it's a solution, not a finished product, so in the hands of different device manufacturers the app experience varies wildly.

My judgment is: treat it as "a second, very small screen" and you'll be fine—don't expect it to replace your phone.

After learning this, the next thing to try is the teleprompter. Paste in your script, and during a meeting the subtitles scroll up line by line—it's more demanding on display rhythm than translation, and better tests the limits of these glasses. I've used transcription for two months, and combined with it for meeting minutes, that's currently the most practical combo I've found.
