This product does not support offline use. It needs to be paired with the mobile phone via Bluetooth, and the mobile phone also needs to be connected to the network and Wifi.

167mm×151mm×46mm

The battery capacity of the charging case is 3100mAh, and that of the glasses is 245mAh. They can be taken on a plane.

For privacy and battery life considerations, the glasses are not equipped with a camera or a speaker.

:Myopia lenses are made of resin material. Display lenses are made of glass material.

Yes. The HEY app (iOS & Android) syncs your glasses for language settings, conversation history, and firmware updates.

Most angles won't show it; only at close range from certain side angles can it be seen.

You can set the automatic screen-off duration of the glasses, or manually press the power button under the left temple once to turn off or turn on the screen.

Glasses are of daily waterproof grade. Do not soak them in water, do not clean them under running water, and do not use them in the rain. When cleaning is needed, simply wipe them carefully with a glasses cloth, a soft damp cloth, or alcohol-free wet wipes. 2. If water ingress is detected, please turn off the device first, wipe it dry, and ensure it is placed in a well-ventilated and cool place to dry before continuing to use it.

In daily communication, there will be breaks, and generally, eight hours of usage can be achieved. However, if speaking continuously, the usage time is approximately six hours. If you have higher usage requirements, you can carry the charging case with you, and quickly recharge it during breaks such as when going to the toilet or taking a rest to replenish the battery.

3. Long press the power button of the glasses for 3 seconds to turn them off, and long press the power button again to restart them after they are turned off.

After adjusting the font, the glasses will load the font library, and the loading is not yet complete. It is recommended that you first exit the subtitle function and then re-enter later. If there is still no change after the operation, you need to exit the software, clear the background, long press the power button on the glasses to restart, and then reconnect, and generally there will be no problem.

If it currently feels tight, it's because it's newly manufactured, and the hinge has elasticity. To ensure a more stable fit when worn and prevent it from shaking or falling off while walking, there is a certain amount of tension. It is recommended to wear it more often to get used to it, and after wearing it for a while, the hinge will loosen slightly, allowing for a better fit to the head circumference.

The specific processing plan is with the supplier. The processing of the lens itself is relatively difficult, and the plano-concave lens used is inconsistent with the usual eyeglass solution. Generally, optical shops often do not have matching lenses and cannot perform the processing. It is recommended to use the official lenses; otherwise, damage or discomfort during wearing may occur.

The surrounding noise when using the glasses, the volume of the speaker's voice, their accent, whether there are multiple speakers, and whether a mask is worn can all have an impact on the translation result.

Each HEY2 package includes the glasses, a charging case, quick-start guide, and microfiber pouch.
