With the SoundEar 3 you also get flexible light settings, including day and night settings.

The first time you connect your SoundEar 3 to your PC, Windows Update will try to find a driver for the software (this may take a while – around 5 minutes) – after this, Windows will “give up” and install a standard HID driver.
When the driver is installed, the device should connect to the software. You can check in your ‘Device manager’ in Windows to see if the ‘HID compliant system controller’ is installed – this would be your SoundEar 3 device.
