For the first time use, please fully charge the earphones and the charging box. Use a national CCC certified charger produced by regular manufacturers with a rated voltage of 5-5.5V.

  4. Note: If the charging box is charging the earphone or an external USB is charging the charging box, the charging box indicator will flash slowly.

5.2 Charging the Charging Box

  • When the charging box itself is low on power, its indicator will flash slowly. Connect the charging box to a power source using a compatible charger (5-5.5V rated voltage or computer USB charging) to charge it.

5.3 Storing Headphones

  • When not in use, the headset can be placed in the charging box for recharging. It must be taken out when it is used. The headset will automatically turn on and connect back to the mobile phone.
  • Note: When the power of the headset is completely discharged, the charging box can charge the pair of headphones 2-3 times simultaneously.
