Maintenance

Cleaning

• Regularly clean the eartips and the mesh filters of the headphones to prevent wax buildup, which can affect sound quality.
• Use a soft, dry cloth to wipe the headphones and charging case. Do not use alcohol, benzene, thinners, or other solvents.
• Ensure the charging contacts on both the headphones and the case are clean and free of debris.

Water and Dust Resistance (IP55-equivalent)

The headphones are rated IP55-equivalent, meaning they are protected against dust ingress and low-pressure water jets from any direction. This rating applies to the headphones only, not the charging case.

• Do not submerge the headphones in water.
• Ensure the headphones are completely dry before placing them back into the charging case to prevent damage.
• The water resistance is not permanent and may decrease over time with normal use.
