Feature overview

You can connect the glasses to two devices simultaneously, and switch seamlessly between the two devices as needed. The glasses support connection to a wide range of Bluetooth devices, including mobile phones, tablets, PCs, and Huawei watches, and work with all major device brands and operating systems.

1. If a watch has been connected to another device, the glasses will not be able to connect to the watch.

2. After the glasses and AI Life app have both been updated to their latest versions, open the AI Life app, access the glasses card, touch the settings icon (four-dot icon) in the upper right corner, and enable or disable Dual connect.

3. After the glasses have been connected to two devices, they will only be able to support audio playback from one of the devices. For more information about the audio output rules, see the rules shown below.

How to connect

1. Connect the glasses to the glasses case, press and hold down on the Function button on the glasses case for about three seconds, and then release. The indicator will flash white, indicating that the glasses have entered Pairing mode. Use device A to search for the glasses and initiate a pairing.
2. Connect the glasses to the glasses case, press and hold the Function button on the glasses case for about three seconds once again, and release. The indicator will flash white, indicating that the glasses have entered Pairing mode. Use device B to search for the glasses and initiate a pairing.

   Once device B is connected to the glasses, the glasses automatically reconnect to device A, so that they are simultaneously connected to both devices.

   

   While the glasses are connecting to device B, the Bluetooth connection between the glasses and device A will be temporarily disconnected.

How to check connected devices

1. Find the list of paired devices on a connected device, such as a phone, tablet, or laptop.
2. Open AI Life, access the device card, and view the connected devices in Audio Connection Center.

Laptop: On a laptop running Windows 10, click the Start icon, go to Settings > Bluetooth and device, and check whether the name corresponding to the glasses is displayed.

Audio output rules for Dual connection

• The priority is as follows: calls > music/video playback. Music and video playback have the same priority. The more detailed rules are shown in the table below.

  Device A	Device B	Audio Output Description
  No services	Incoming calls	The glasses will play the audio from device B.
  	Music or video playback
  Ringing upon an incoming call	Incoming calls	For a call to device A, the glasses will play the phone ringtone. For a call to device B, the glasses will play the ringtone preset on the glasses. The glasses will answer calls to device B, and the call audio on device A will switch over to the device's receiver.
  Media playback or voice call in progress	Incoming calls	Call audio on device A will switch over to the device's receiver, and music/video will either pause or played via the speaker. The glasses will play the call audio on device B. Once the call on device B ends, the glasses will resume playing the audio from device A.
  	Music or video playback	The glasses will play audio from device A. Media audio (music/video) on device B will play via the speaker. The glasses will play audio on device B once the call has ended or music/video is paused on device A.

• Connecting to a third device C: The Preferred device is reserved. To cancel a specific device, disconnect from the device and then connect to the new device.
• Voice assistant/Starting a music app: Wake up or initiate the Preferred device service.

Definition of a preferred device:

• When no audio service (music, video, or call) is running on the two connected devices A & B, the first connected device is regarded as the preferred device.
• When audio service (music, video, or call) is running on both devices A & B, the most recently used device is regarded as the preferred device.
• The issue of the glasses playing audio that should be played on the earphones will be resolved in later phone versions.

Calls and communications in third-party apps and games are regarded as calling scenarios.
