I found the Xtrons manual to be very helpful to me in understanding most of the capabilities of the Eonon. Yes, they look like the same body, engine and suspension with a few tweaks.

One of the things I immediately noticed in going through the Xtrons manual is that their equalizer app does NOT have a subwoofer volume slider.
PS: It looks like Xtrons has an E53 unit with 2GB RAM and a 32GB ROM.
