Common Pairing Style

1. Normal Pairing Style:

The indicator lights will flash alternately, entering the ear-to-ear search and pairing state. Automatic pairing will commence. After successful pairing, the main earbud's indicator light will flash alternately, the secondary earbud's indicator light will turn off, and an ear-to-ear pairing success tone will play.
   2. Enable the wireless function on your phone or other device. On Android phones/devices, tap the "Search for wireless devices" option. On iOS phones/devices, it will search automatically. Once the wireless earbuds model is found, tap to enter pairing. Upon successful pairing, the earbuds will emit a connection success tone, the indicator lights on both earbuds will turn off, and they will enter connection standby mode. The right earbud will function as the right channel, and the left earbud as the left channel.
   3. Both earbuds can also be paired individually with a mobile phone. Follow the same procedure as described in Step 2.

Charging Operation

1. Charging the Case: Connect one end of the Micro USB charging cable to the charging case and the other end to a charger. The charger should be a standard 5V 1A charger for the charging case.
2. Charging the Earbuds: Place the earbuds into the charging case for automatic charging. The earbud indicator lights will illuminate during charging and turn off when fully charged.

Precautions

1. Please charge in a safe environment. Once the charging case is fully charged, disconnect it from the charger as soon as possible to prevent damage from prolonged charging.
2. When playing music, adjust the volume to an appropriate level to avoid long-term hearing damage from prolonged high volume.
