Razer Nommo 2.0

I just received my new speakers from Razer today and I had a few questions that I needed help with.  My speakers are the regular Razer Nommo 2.0 (the older ones not V2). On the original image it showed that these have RGB lights, but it seems they actually either don’t have them or are not working on mine. Does anyone know if these actually have RGB lights? My box does not say chroma on it which are the ones I actually wanted. Also in the instruction manual it stated to connect the 3.5mm plug into the input port of the back of the right speaker but when I do that only the right speaker will actually work, but if I connect it into the AUX port then they both will work. Seems kind of weird that it is like that, does it truly matter if I leave it plugged into the AUX port? Sorry if these questions seem ridiculous but this is the first desktop that I’ve have and only had laptops before with no extra speakers. Thanks.
