You will need to use an Android device to set up the SXFI AMP. This is a one-time setup process where you take the pictures of your ear/head, and this profile is downloaded to the SXFI AMP connected to that Android device.

After this is done, you can unplug the SXFI AMP from the Android device, and then you're free to use it with any other devices (Mac / Windows PC / laptop / PS4, etc)
