Maintenance and Cleaning
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 sleeves if they do not fit properly.
Do not attempt to modify this product. Doing so will void the warranty and could result in personal injury and/or product
failure.
Cleaning the Nozzle
If you notice a change in sound quality, remove the sleeve and check the nozzle of your earphone. If nozzle is blocked, clear
obstructions.
If no obstruction is found or if sound quality does not improve, replace the sleeve with a new sleeve or disassemble the nozzle
to clean inside.
Caution: When cleaning, do not force any object through the earphone nozzle! This will damage the earphone sound filter.
