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 Earphone Nozzle
If you notice a change in sound quality, remove the sleeve and check
the nozzle of your earphone. If nozzle is blocked, clear obstruction by
using wire loop end of cleaning tool.
If no obstruction is found or if sound quality does not improve, replace
the sleeve with a new sleeve.
Cleaning Tool
Caution: When cleaning, do not force any object through the earphone nozzle!
This will damage the earphone sound filter.
Warning: The cleaning tool is only to be used to clean the earphones. Any
other use, such as using the tool to clean ears or foam sleeve, could result
in injury.
