Troubleshooting
< Diminished Sound Over Time
If you experience lower performance over time, use the cleaning tool to make certain that the
ear conductor is unobstructed.
< No Sound
If you are not receiving any sound, make certain that the jack is properly attached to your
listening device and that the volume has been gradually increased. If you are still not receiving
sound, confirm that the connections between the cable and your earphones are secure.
If the suggestions listed above do not solve your problem, please contact one of our customer
service representatives.
