Do not use when a failure to hear the ambient noise could be hazardous,
such as while operating vehicles or heavy machine, while bicycling, jogging,
or walking near traffic.
Prior to inserting the earphone, always recheck whether the sleeves are firmly
attached on the nozzle. When inserting or removing the earphone, please twist it
in or out slowly. Never pull on the earphone cord.
If a sleeve becomes lodged inside your ear, seek professional medical assistance to
remove it.
While using the earphone, make sure the volume level is proper, and would not
damage your ears. Ringing or humming in the ear may be the symptom of excess
sound level, please try to low the volume.
When connecting the earphone in the airplane, use as low a volume as possible so
that the voice from the pilot would not cause discomfort.
Checked by an audiologist on a regular basis and in any other situations that make
you discomfort in wearing the earphone.
