FOUR-MICROPHONE ARRAY

360° pickup. Clearer face-to-face conversations.

Four microphones provide broad coverage for nearby voices from different directions. In a one-to-one conversation, face the speaker and stay close for the clearest recognition.

  • 360° pickup — captures nearby voices from different directions
  • Face-to-face pickup — clearest when you face the speaker and stay close
  • Speech-focused processing for live recognition and translation

Results vary with background noise, distance, overlapping voices, speech clarity, language and phone/network conditions. In quiet settings pickup may extend farther; in noisy settings stay closer to the speaker.

QUESTIONS, ANSWERED

Good to know.

Clear answers about fit, privacy, battery, display and everyday care.

Ask LEION Support
What are the frame dimensions and weight?

Hey2 measures approximately 167 × 151 × 46 mm and weighs 49 g.

Does Hey2 have a front-facing camera or speaker?

No. Hey2 has no front-facing camera and no speaker. Translated text appears in the optical display; translated voice output for supported modes is handled through the connected phone.

How far away can Hey2 pick up speech?

In quiet conditions, pickup may work at distances up to about 10 meters. In noisy environments, stay within roughly 3 meters for better results. Performance varies with noise, voice clarity, overlap and connection quality.

Will the battery always last eight hours?

Up to 8 hours reflects typical daily use with natural pauses. Continuous speech recognition may reduce runtime to around 6 hours. The charging case can top up the glasses during breaks.

Is Hey2 waterproof?

Hey2 is intended for everyday splash resistance, not immersion or use in rain. Do not rinse it under running water. Wipe it with a lens cloth, soft damp cloth or alcohol-free wipe. If water enters the device, power it off and let it dry fully in a ventilated place before use.

Can another person see the green display light?

Front light leakage is reduced for normal face-to-face viewing at eye level. At close range and certain side or low viewing angles, another person may still notice some text or green light.

Can I turn the caption display off quickly?

Yes. Set an automatic screen-off time in the app, or press the power button under the left temple once to turn the display off or on.

Why do I see reflections or ghosting in dim light?

Reflections can become more noticeable in darker environments. Lower the display brightness to reduce glare, visual fatigue and visible ghosting.

What materials are used for the lenses?

Custom prescription lenses use resin materials. The display optical element uses glass. Available prescription options depend on the values you submit.

Specifications and feature availability may change with product and app updates.
