Check the position of your earplug.
If it sits too far out of the ear or is too
loose, please select a different size.
Check the position of the hearing
amplifier behind the ear. If the
microphone opening is covered
by the ear itself or a large amount
of hair, change the position of the
hearing amplifier in order to keep the
microphone opening clear.
