A review of the smart glasses I’ve used

Xiaomi AI Glasses

Totally shit, I am the biggest idiot of all who paid 1999 for this garbage.

Pros

  1. At 40 g, they are fairly lightweight
  2. The BES2700 + AR1 dual-chip design is efficient: listening to music only activates the BES2700 Bluetooth audio chip, giving strong battery life
  3. USB-C charging: connect a power bank for effectively unlimited battery life

Cons

  1. The frame feels very plastic, and the temples will inevitably become covered in scratches during normal use
  2. The temples are too thick, and the overall appearance is only average
  3. The sound quality is terrible. There is some sound leakage, though it is still acceptable
  4. No display
  5. Without a Xiaomi phone, the AI features are severely limited

Quark AI Glasses S1 (Qwen AI Glasses S1)

These are my current main glasses. In my opinion, considering everything together, they are the best choice as of April 2026.

Pros

  1. The BES2800 + AR1 dual-chip design offers better performance and power efficiency than Xiaomi’s BES2700
  2. Single-green two-dimensional grating-diffraction waveguide with a peak brightness of 4,000 nits. It is fine under normal conditions, but remains invisible under strong midday sunlight. There is almost no light leakage from the front, although noticeable leakage remains at certain angles, mainly when looking at the lenses from below
  3. Binocular display with adjustable display-area focus distance and vertical position, making it adaptable to different use cases
  4. Backed by Alibaba, with the richest ecosystem support. Navigation, payments, food delivery, transportation, and more are supported by first-party services
  5. Powerful voice control: all features can be accessed by voice, and nearly all system settings can be changed by voice
  6. The temple material is comfortable, skin-friendly, and resistant to scratches
  7. The battery has a capacity of 287 mAh, of which 240 mAh is replaceable

Cons

  1. They cannot be used while charging. The temples must be folded during charging, and replacing the battery interrupts use
  2. Sound leakage is more serious than with the Xiaomi AI Glasses
  3. The charging connector is proprietary, so official accessories are required
  4. The activation phrase is less resistant to wind noise than on the Xiaomi AI Glasses. Voice activation is essentially unusable while cycling, although recent OTA updates have improved this somewhat
  5. At 52.5 g, they are relatively heavy. However, the front-to-back weight balance is good, so they feel reasonably comfortable

Quest 3

Strictly speaking, this is not a pair of smart glasses, but it is worth mentioning briefly.

Pros

  1. When connected to a PC, it can provide three separate screens. The clarity is acceptable, and the viewing experience is excellent
  2. It can be used for office work with some compromises, but the experience is not particularly good because of the limited clarity

Cons

  1. A VPN is required, and the router must use transparent proxying. Installing an app inside the headset cannot fully solve the network issue
  2. This is beyond ordinary sound leakage: it uses open speakers, and everyone in the room can hear everything clearly
  3. Native Air Link PC streaming is poor. For the best experience, you need to purchase the third-party app Virtual Desktop

The Meta app store is relatively expensive, but it has a loophole that Steam had before. You can buy across regions and send purchases as gifts, allowing games and software to be obtained at a lower price.

Quest 3S

I briefly tried it at a friend’s place. Because both the lens design and resolution have been cut back, the image feels almost visually blurry compared with the Quest 3. It is fine for entertainment, but basically unusable for office work. Overall, I do not recommend saving this relatively small amount of money at the cost of such a significant experience downgrade.

Conclusion: If you need one, buy the Quest 3.
