Most people have sat through a conversation where language became a wall, nodding along, catching fragments, and missing the point. The Leion Hey 2 AR glasses are built on the idea that communication should not be a guessing game. Subtitles appear in the wearer’s line of sight as others speak. Outgoing words are translated and delivered in real time. A four-microphone array with spatial audio perception handles crowded, noisy environments and keeps speech recognition sharp. Audio is captured locally on the device and projected onto the AR display, with translation latency under 500 milliseconds, reaching as low as 200 milliseconds. The glasses achieve up to 98% speech recognition accuracy and support over 100 languages. Battery life ranges from 8 hours on a single charge to approximately 2 weeks with the portable charging case. The Hey 2 packs all of this into a browline frame weighing just 49 grams.

Built for Real-World Communication Needs
Language barriers arise during business meetings, presentations, or everyday conversations. Previously, people relied on phones, notes, or interpreters. Hey 2 brings real-time translation, live transcription, a smart teleprompter, and AI assistance, helping users a way to connect, present, and collaborate across languages without breaking their focus.
Free Talk Mode
Understanding what someone says in another language is one challenge. Responding in that language, in real time, is a different one entirely. Free Talk mode in the Hey 2 takes on both at once. As the other person talks, translated subtitles appear right in the lenses. As the wearer talks back, their words are translated and sent out as a clear voice and text. The whole exchange runs at under 500 milliseconds, reaching as low as 200 milliseconds, keeping the conversation fluid and uninterrupted.
How Real-Time Speech Translation Works
Not every situation calls for a back-and-forth conversation. In meetings or while travelling, the priority is often just understanding what is being said. For those moments, the Hey 2 operates in Real-Time Translation mode, turning foreign speech into the wearer’s native language in real time, with subtitles projected directly into the field of view.
The glasses support over 100 languages and accents, including regional dialects, everyday speech variations, and classical literature forms. Subtitles are adjustable, so wearers can set the display to suit how they read best.
How Does the Teleprompter Feature Work in AR Glasses?
Hey 2 includes a smart teleprompter feature. Speeches are uploaded to the Leion app beforehand, and as the wearer speaks, the glasses listen to every word, recognize them instantly, and auto-scroll the script lines right in the lenses. Because the text advances in response to what is actually being said, presentations flow naturally, with lines always in the right place and no awkward pauses mid-delivery.
AI Q&A
The Hey 2 integrates ChatGPT to deliver precise, up-to-date answers directly in the wearer’s view. Any question asked verbally, whether about technical specs, meeting questions, or general trivia, gets a precise, up-to-date answer displayed instantly in the lenses. The AI also generates meeting minutes and live translation summaries, summarizing conversations as they happen.
360-Degree Spatial Audio and Noise Cancellation
Audio quality drives how well the Hey 2 performs. A smart four-microphone array gives the glasses all-around audio capture, detecting voice sources across a full 360-degree field and boosting speech recognition even in the noisiest environments.
Leion’s proprietary beamforming, working alongside multiple noise cancellation layers, instantly isolates the speaker’s voice and eliminates background noise, producing crystal-clear pickup and higher speech recognition accuracy.
In a one-on-one conversation, directional voice capture follows the wearer’s gaze. In a group setting, the glasses intelligently mute everyone around and zero in on the voice directly in front of the wearer.
Prescription Lens Option
For wearers who need prescription lenses, the Hey 2 offers a premium option that fits the frame without screws or traditional mounting hardware. A one-click magnetic mount keeps installation simple and minimizes the risk of damage in the process. The design is completely rimless, which opens up the widest possible field of view. The lenses themselves are thinner and noticeably lighter than standard prescription lenses, putting less weight on the nose throughout the day. They are made for all-day wear and designed to look as good as they feel.
Display Lens: Plano-Concave Optical Structure
The display lens in the Hey 2 uses a flat-concave optical structure. That flat outer surface fits the AR waveguide precisely, which keeps the display free of distortion and maintains sharp focus across the full lens, from edge to edge.
The lens comes with an impact-resistant coating and dual-surface protection, making it scratch-proof, drop-resistant, and easy to clean.
A multi-layer low-reflection green coating reduces glare from every angle. Under harsh lights or bright sun, it produces sharper vision and dramatically reduces eye strain.
Speech Recognition Accuracy
The Hey 2 uses advanced AI speech recognition to achieve up to 98% accuracy across over 100 languages and dialects. Translation latency runs under 500 milliseconds, reaching as low as 200 milliseconds, enabling smooth, real-time conversations without delay.
Frame Design and Connectivity
The Hey 2 comes in a browline frame, a classic eyewear style associated with wisdom and sophistication. The frame is available in black and weighs 49 grams. Physical dimensions measure 167 x 150 x 46 mm, and the AR display resolution is 480 x 640 pixels. The glasses support Bluetooth 5.4 and dual-band Wi-Fi on 2.4 GHz and 5 GHz, with magnetic charging and compatibility with Android 8.0 and iOS 11.0 or later.
Runtime and Charging Details
The glasses carry a 245 mAh battery that delivers up to 8 hours of uninterrupted use on a single charge. The portable charging case has a 3,100 mAh capacity and provides up to 12 full recharges. To power up, simply place the glasses inside the case. With the case included, total usage time can reach up to two weeks between wall charges. The case is portable, making it easy to carry throughout the day.

Good Enough to Wear Every Day?
There is a particular kind of frustration that comes from understanding a language just well enough to know what you are missing. The Hey 2 was developed with that gap in mind. Real-time translation in both directions, live transcription, a speech-reactive teleprompter, and AI-assisted Q&A all work across more than 100 languages and dialects, with speech recognition accuracy reaching up to 98%. The frame weighs 49 grams, runs for up to 8 hours on a single charge, and extends to approximately two weeks with the portable charging case. AR glasses are still finding their footing in daily life. The Hey 2 is compact and functional for all-day wear.
