MAINTENANCE
Careful maintenance ensures a tight seal between the sleeve and nozzle,
improving sound quality and product safety.
Keep the earphones and sleeves as clean and dry as possible.
To clean sleeves, remove them from earphones, gently rinse in
warm water and air dry. Foam sleeves require a longer drying
time. Inspect for damage and replace if necessary.
Ear sleeves must be completely dry before reusing.
Wipe the earphones and sleeves with mild antiseptic to avoid
infections. Do not use alcohol-based disinfectants.
Do not expose earphones to extreme temperatures.
Replace the sleeves if they do not fit properly.
