Xiaodu Pro AI Glasses vs Halliday (DigiWindow) in 2026

Xiaodu Pro AI Glasses

The Baidu Xiaodu Pro AI Glasses are camera-and-audio AI glasses with no display (explicitly not AR glasses): 39 grams, titanium hinges, a Sony 12-megapixel camera (4K photo, 1440p/30fps video), a four-microphone array, and prescription-lens support, in Boston and Cat-Eye styles. They went on sale in China on November 11, 2025 via JD.com and Tmall at 2,299 yuan, roughly $322, with next-day delivery.

The AI is genuine and primary, built on Baidu's ERNIE large language model (first-person 'ask about what you see' Q&A, object and calorie recognition, encyclopedia lookup, audio and visual translation, reminders), and made via Baidu's Xiaodu Technology subsidiary; the assistant runs on ERNIE, not on Xiaomi's XiaoAI. They complete the Chinese consumer wearable-AI cohort alongside Xiaomi AI Glasses and the RayNeo V3.

Cap-flag: pricing is China-market CNY (the USD figure is a conversion) and the glasses are not officially sold outside China; the AI is cloud-dependent rather than on-device.

Halliday (DigiWindow)

The Halliday glasses are display-first AI glasses built around DigiWindow: a roughly 3.5mm MicroLED projector on the inside of the upper-right rim that beams a monochrome green ~3.5-inch virtual display above the eyeline (a projection, not a lens waveguide), in ~35-gram conventional frames with no front camera, a touchpad, and an optional ring controller. Features include real-time translation (40 languages, demoed), notifications, navigation, a 'Cheat Sheet' teleprompter, and a 'proactive AI' Echo Mode.

DEPLOY records it at pilot maturity: it launched via Kickstarter ($369 backer price, $489 retail) rather than full retail shipping. Its differentiator is the eye-projected display plus proactive AI, not eye-tracking (no eye-tracking is on record), and it has no camera. Cap-flag: the AI features and translation are demonstrated, and the ~8-hour battery is a vendor claim; verified shipping at scale is not yet established.
