If no obstruction is found or if sound quality does not improve, replace the sleeve with a new sleeve.
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.
The cable connectors to the earphones may collect debris or other deposits that can affect audio quality. If this
happens, disconnect the cables and clean them using a dry cotton swab.
