There are two components of your earphones that can be cleaned:
To clean the silicone ear cushions:
Remove the ear cushions by gently pulling them directly away from the earphones.
Either wash the ear cushions in mild soap and warm water or gently wipe with non-alcoholic or baby wipes.
After cleaning, let the ear cushions sit at room temperature until they are completely dry.
Push the ear cushions back on the earphones.
To clean the sound channels, do the following:
NOTE: Use only the included cleaning tool — any other device may damage your earphones.
Rotate your earphones until the channel is pointing downward.
Gently use the cleaning tool's metal hoop to remove any material stuck inside.
NOTE: Make sure you have the channel pointing toward the ground and use a circular, sweeping motion to prevent anything becoming stuck further up the channel. Don't use any liquids for cleaning the sound channels.
