LLVision launches Leion Hey2 AR translation glasses
LLVision has introduced the Leion Hey2, which it calls the world’s first AI-powered professional AR translation glasses, marking the product’s official launch in the United States. The company says in a release that the wearable is designed to keep multilingual conversations natural by displaying real-time subtitles directly in the wearer’s line of sight.
For eeNews Europe readers tracking the evolution of AI at the edge, AR displays, and human-machine interaction, Hey2 is a useful case study in how optical design, low-latency speech processing, and power management are converging into a new “always-on” communications class. It also signals growing demand for purpose-built translation devices.
Translation-first design, pro runtime
According to the release, Leion Hey2 supports more than 100 languages and dialects, while delivering sub-500 millisecond translation latency in real-world use. LLVision positions the product as translation-centric, rather than a general-purpose smart glasses platform, arguing that many existing approaches compromise human presence by forcing users to look down at phones or rely on isolating earbuds.
LLVision, founded in 2014, says it has spent more than a decade building integrated AI and AR solutions aimed at multilingual communication. Battery life is framed as part of the professional pitch: the company claims six to eight hours of continuous translation on a single charge, plus up to 96 hours of total use when paired with its charging case — positioning the device for full workdays, conferences, and travel.
Optical AR display and accessibility focus
According to the company, the Hey2 uses a waveguide optical architecture paired with a micro-LED light engine to display subtitles in a head-up format. LLVision says the display is intentionally “restrained,” prioritizing crisp text across varying lighting conditions while minimizing distraction — a key requirement for prolonged, real-world use.
The always-visible subtitle approach also enables real-time captioning for Deaf and hard-of-hearing users, according to the release, without requiring separate devices or workflows.
Microphone array, noise reduction and “Free Talk” mode
LLVision highlights audio capture as a differentiator. In Free Talk mode, the system emphasizes voices within roughly a 60-degree forward range while suppressing side conversations and ambient noise. A four-microphone array with 360-degree spatial voice detection identifies the active speaker direction before processing begins, followed by proprietary beamforming and neural noise reduction.
The company says this design aligns audio pickup with natural posture — “who you face” — to keep translation intuitive during meetings, group discussions, and busy public spaces.
Pricing, privacy and availability
Leion Hey2 is available to order in the United States via LLVision’s online store at $549, with a pre-order price of $499 through January 31. Pre-orders include a clip-on sunglass lens and 1,200 minutes of Pro translation service, according to the release. LLVision also states the device has no camera and no external speakers, and that data processing follows GDPR-aligned privacy principles supported by Microsoft Azure cloud infrastructure.
