Normally, the earbuds can be used for around 6 hours in ANC mode and 10 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. Use a dry cloth/cotton swab with rubbing alcohol to clean the charging pins in the charging case and on the earbuds to ensure a better connection. Ensure the ear tips are not blocking the charging connectors and fully charge your earbuds.

2. Turn off the dual connections and 3D surround sound.

3. Test the battery when playing music.

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