Solutions
Tilt your phone speaker slightly away
from the hearing aid on that ear.
Adjust World Volume (see page 30).
This syncs audio settings between the
hearing aids.
Practice listening to new sounds
and talking with a friend in a familiar
environment before you use the
hearing aids for conversation
(see page 39).
If you're using closed eartips, try
replacing them with the same size
open eartips (see page 73).
