Some tips/answers you will not see in the description, as this must be the first review.
1) the Acrylic Shell has a blurry protective film, which you can easily remove with your finger nails.
2) if you add a device in line-in you can disable the in-build microphone from the settings. 3) Inside the package there is a usb-c to usb cable, a 3.5mm jack to 2 RCA Male cable, and a small cable for the "6" special port.
Everything seems to work great so far and for this price is excellent! I use it with my pc speakers, the brightness is high and it looks very cool.
