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)
