Leion Hey 2 AR Translation Glasses

Leion Hey 2 – smart AR glasses with real-time translation, captions and transcription

Leion Hey 2 are smart AR glasses designed for people who want to communicate more freely in different languages and follow conversations more comfortably in real time. The glasses display captions, transcription and translations directly in front of the user’s eyes, allowing conversations to feel more natural.

The device is suitable for travel, business meetings, conferences, learning, work in international environments and everyday conversations. Leion Hey 2 can help in situations where it is difficult to hear or understand the speaker — for example in noisy environments, during group conversations or when communicating in a foreign language.

The glasses use a four-microphone sound capture system, 360° spatial perception and noise reduction algorithms. As a result, the device captures speech more effectively and reduces the impact of ambient sounds. The manufacturer declares translation accuracy of up to 98% and very low latency below 500 ms, enabling smooth real-time conversations.

Leion Hey 2 also offers AI features such as conversation summaries, meeting notes, live translation and AI Q&A with ChatGPT integration. In addition, the glasses can function as a personal teleprompter, which can be useful during presentations, recordings, public speaking or working with text.

The design weighs 49 g and has been created in a classic browline style. The glasses support the HEY mobile app for iOS and Android, allowing users to configure languages, conversation history and firmware updates.
