Xiaomi’s audio glasses are €99.99. No text on the lens, and charging is USB-C

Xiaomi’s official store has a pair of glasses with speakers. The French buy page is €99.99, with a NEW badge. Model MJSSO20FC is on the French and global spec pages. The official German product page lists the same product name at 40 g, and a comparison table at 33.4 g with the lenses off.

What the official pages explain is playback, calls, and charging. They do not write a resolution for putting text or notifications on the lens. These are glasses that put open-ear speakers into a frame you can fit with prescription lenses.

10 hours of playback, 7 hours of calls, and a 2-hour USB-C charge

The global product page says 10 hours of playback, 7 hours of calls, 24 hours of general use, and 11 days of standby on a full charge. It notes that the numbers are from the maker’s lab, and that they change with playback level and the device you connect. Charging works with any USB Type-C, and under the same conditions it takes 2 hours from 0% to 100%.

The spec’s box contents are the right temple, the left temple, a removable frame, a charging cable, a cloth, a pouch, a manual, and a warranty card. Replacement frames are sold separately, and the page says prescription lenses are fitted afterward the same way as ordinary glasses.

The speaker is an ultrasonic speaker called SLS0820, and it carries sound through the air. Because it does not block the ear, the page says you can hear the audio around you and the playback at the same time. It also says call leakage is held down with inverted waveforms and an isolation membrane. Six detection points watch whether you put them on or take them off. Playback stops when you take them off, and resumes when you put them on.

40 g and 33.4 g sit side by side, with and without lenses

The full unit in the spec table is 40 g. The comparison table on the same global page sets the weight with the lenses off at 33.4 g. The frame is nylon, and the hinge is a first-generation quick release. There are two microphones, and Bluetooth is 5.2. Fast Pair is not supported, and connecting two devices at once is not supported either. The app row says “Not supported,” and the recording row is blank.

Mijia Smart Audio Glasses, next to that comparison table, is another generation. Weight without lenses is 32.3 g for Pilot-Style, 32.4 g for Browline, and 27.6 g for Titanium. There are four microphones, 13 hours of continuous playback, 9 hours of calls, about 1 hour to charge, and Bluetooth 5.4. There is an app, two-device connection, and the recording row lists ambient audio, online meetings, calls, and audio-and-video scenes.

What you can buy for €99.99 is the Xiaomi Smart Audio Glasses column in the comparison table. Saving a meeting, and an app just for the glasses, are written on the Mijia rows.

What it wakes is the assistant on the phone you connected

The touch control is on the temple side. A long press on the right rejects a call and wakes the voice assistant. The page’s note says that waking the assistant requires a Bluetooth connection to a phone. The glasses have no app of their own. What you are waking is the assistant on the phone.

Dust and water resistance is IP54, meant for sweat and splashes. It also says not to wear them for water sports.

Built the other way from an everyday pair you read text on

Ray-Ban Meta Audio is the audio model with neither a camera nor a display, placed in a cheaper band than the camera pair, and that one starts at $349. This Xiaomi pair is €99.99, and it hands the assistant to the phone. Recording and translation closed inside the glasses are not in this model’s table.

If you read everyday notifications and translation as text, that is the side of Even G2, which has no speaker. Even G2 sends things back as a display, and it has no speaker. Xiaomi’s MJSSO20FC is the reverse: what it sends back is the speaker. For someone who wants music and calls without blocking the ears, this €99.99 column is the closer one. On a day you want to keep a conversation, or put text on the lens, look at another pair.
