Perform regular maintenance by following the procedures below.
Remove the earbud tip.
Hold the headset unit and twist the earbud tip while rotating it to pull it out.
Do not pinch the end of the earbud tip when removing it.
Clean the headset.
Cleaning the headset units
When the headset exterior is dirty, wipe it clean with a soft dry cloth. If the headset is particularly dirty, soak a cloth in diluted neutral detergent, and wring it well before using it to clean the headset. Do not use solvents such as thinner, benzene, or alcohol, as they may damage the surface.
Use a soft dry cloth to wipe off any water that gets on the headset.
Do not allow the headset to remain with water droplets attached in a cold environment as the water may freeze.
Cleaning the microphone parts
Wipe off any dirt on the mesh part of the headset unit with a cloth that has been moistened with water and wrung out tightly.
Remove the dirt so that it does not push into the mesh part of the headset unit deeply.
Cleaning the charging ports
If foreign matter or moisture, such as sweat, etc., is left on the charging ports of the headset units or charging case, charging port corrosion may occur and prevent charging.
When you have finished using the headset, make sure to gently clean the charging ports with a soft dry cloth or cotton swab.
When the headset cannot be charged, it may help to try thoroughly cleaning the charging ports.

Drying the headset

Attach the earbud tip.
Firmly insert the earbud tip all the way. Do not attach the earbud tip in a loose or skewed manner.
If the earbud tip is not completely attached, the earbud tip may be removed from the headset and the sound quality, noise canceling effects, and wearability may deteriorate.
Set the headset in the charging case.
After maintenance as well as after cleaning and drying the headset, be sure to set the headset units in the charging case.
Be sure to close the lid of the charging case.
