Ready to hear better with your new HD75 device?
It may take some time to get used to the amplification provided by your
new device. You will hear many sounds with clarity that you are not
used to hearing. Ambient and environmental sounds like shuffling papers,
cutlery, and dishes may be distracting at first. Your brain needs to get
used to these sounds. We suggest trying to use your new device
regularly over the course of about two weeks as you will need to
adapt to the brighter and clearer sounds the HD75 will provide.
HD75 app
Although your HD75 comes ready to use out of the box, you have the
option of downloading the free HD75 app onto your smartphone for
optimal customization (see page 14).
Please read all instructions before wearing devices.
