LLVision Leion Hey2

Leion Hey2 is LLVision's translation-only glasses, on sale in the US since January 6, 2026 at US$549 (CNY 3,999 in China, per a VR Tuoluo review from January 29, 2026). Four microphones feed live captions onto a green single-color micro-LED waveguide, with no camera and no speaker on the frame.

VR Tuoluo's test logged 8 hours of continuous translation, ending at 74 percent battery after a 2-hour run, and called the 49g frame close to regular glasses. NotebookCheck and Gadget Flow both praised the display's legibility in direct sunlight, and Gadget Flow measured speech-to-caption latency under 500 milliseconds.

## Can you build for it LLVision lists a Developer Kit bundling the glasses, a case and an SDK for display and sensors, but the product page now redirects to the LLVision homepage and no public documentation was found. VR Tuoluo also flags that the on-device AI assistant runs through a single cloud provider, Coze, tying every session to that one backend.

Reviewers logged real limits too: NotebookCheck found the plastic arms discolor despite the magnesium-lithium frame and described a visible glow from the display's light diffraction. VR Tuoluo noted the knowledge base can run outdated and fast speakers can outrun the subtitles. With no camera and no confirmed price outside the US and China, Leion Hey2 fits one job, not general-purpose AR.
