• Once you have updated the AI Life app plug-in to 2.1.0.54 or later, the Smart HD option for FreeBuds Pro 2 and FreeBuds 5i will change to Prioritize connection quality or Prioritize sound quality.

To enable HD audio quality, perform the following steps:

1. Pair and wear your earbuds.
2. Update the AI Life app plug-in and Audio Accessory Manager to their latest versions.
3. You can open the AI Life app, access the earbuds card, and set the Sound quality & effects to Prioritize sound quality.
   • Prioritize sound quality: The Bluetooth codec is LDAC or L2HC. Enabling this feature brings high-quality audio experience.
      

     • Enabling Prioritize sound quality improves audio quality, but may also affect the earbuds' battery life and cause stuttering. It is recommended that you select Prioritize connection quality or do not use Prioritize sound quality in environments with high interference, such as in stations and at airports.
     • Once you've enabled HD spatial audio, the audio codec cannot be changed. After this feature is disabled, the original settings will be restored.
4. If you are using an Android device, you can then go to Developer options > Bluetooth audio codec, and select LDAC.

If the earbuds are used with a non-HUAWEI phone, the effects may not be obvious because your phone does not support LDAC, or your phone restricts the use of LDAC. For details, please contact the phone manufacturer.
