Normally, the earbuds can be used for around 10 hours in ANC mode and 12 hours in Normal mode at 50% volume, but playtime may vary slightly based on the music content and volume. If you use the earbuds to make/receive calls, playtime will be shorter as it consumes more power than playing music. Please note that a difference of less than 1 hour between the left and right earbuds is considered normal.

Since the earphones are divided into master and slave ears, the right ear is usually the master ear by default, and the power consumption of the master ear will be higher than that of the slave ear, so there is a difference in power consumption between the left and right ears, but usually within 1 hour.

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 of both the earbuds and the case. Make sure the ear tips are not blocking the charging pins, then fully charge your earbuds.

3. Charge the case with a different charging cable and wall charger, and make sure the case has sufficient power.
