4. Hold the sound tube in place and carefully position
the earplug in the ear canal. Make sure not to
insert the earplug too deeply into the ear canal.
If the earplug is not properly in place or feels
uncomfortable, try a different earplug.
5. Place the fixing tube along the outside of your ear.
This ensures that the earplug fits tightly in the ear.
If the fixing tube bothers you, you can cut it off. It is
not absolutely necessary.
Check whether you have selected the correct size of earplug by moving
your head slowly up and down and then left to right while opening and
closing your jaw. If the earplug slips out, it is too small. If you wear
glasses, place the arm of the glasses between your head and the
hearing amplifier.
