The LED indicator will turn red during the charging process and the headphones will automatically turn off. The LED indicator will turn from red to blue when charging is complete.

Storage and Maintenance

  • Store the headphones in a cool, dry place. The working temperature should be 0~40°C (32-102°F).

  • Stop using the headphones immediately if any parts are damaged, smoking, hot, or have a burning smell.
  • The headphones' liquid and dust resistance level is IP55. It can be used in non-water sports and exercises and is not fully waterproof. Do not place the headphones in water. IP55 is not a permanent protection rating and may be reduced by normal wear and tear.
  • Clean the headphones with a soft dry cloth.
  • After storage for a long period, please charge the headphones before using again.

Hearing Loss

Listening with headphones at high volume may affect your hearing and the audio will be distorted. Please do not listen with headphones at high volume for a long time.

Battery

CAUTION

  • Replacement of a battery with an incorrect type that can defeat a safeguard.

Charge

  • Always confirm that the charging port is dry before connecting the device to the charging cable. Failure to do so could result in increased possibility of short circuit issues, fire or explosion danger.
  • Do not charge right after exercising in case there's sweat inside the charging port, which could lead to circuit burning while charging.
  • Keep the headphones away from heat sources when charging.
  • Only power supplies that have been approved by relevant departments and meet local regulatory requirements (such as UL, CSA, VDE and CCC) shall be used.
