Normally, the earbuds can be used for around 8 hours in ANC mode and 12 hours in Normal mode at 50% volume, but playtime may vary slightly depending on the music content and volume. When using the earbuds for calls, battery life will be shorter, as calls consume more power than music playback. Please note that a difference in remaining playtime of less than 1 hour between the left and right earbuds is considered normal.

If the difference is beyond 1 hour, please try the following:

1. Ensure the protective film has been removed from the earbuds.

2. Use a dry cloth or cotton swab with rubbing alcohol to clean the charging pins in the charging case and on the earbuds to

ensure a good connection. Ensure the ear tips are not blocking the charging connectors and fully charge your earbuds.

3. Charge the charging case with a different charging cable and wall charger and make sure the charging case has enough power. When the indicators turn off, the charging case is fully charged.

4. Test the battery by playing music.

ANC is turned on by default. If you want to test the playtime in Normal mode, switch to Normal mode first.
