Dome types
Within each dome size, there are two types of domes:
open and closed.
Open domes (attached to
the hearing aids) help your
voice sound more natural.
They have holes around
the center of the dome.
Closed domes provide
more bass and allow
you to comfortably use
a higher World Volume
setting.
Try another dome type
During rst-time setup, use the default open domes
and focus on nding the correct size for each ear.
After using the hearing aids for some time, if you feel
like you need more amplication or hear whistling at
higher World Volume settings, consider trying closed
domes.
