Everything is fine. But the main disadvantage is bad microphones. And microphones, as you know, play an important role in karaoke. I connected my old microphone directly to a separate speaker, it also pulls badly. Conclusion, you have to spend money on buying a better one. If you buy X-Star and the sound quality of your voice is important to you, I advise you to immediately buy other microphones for this karaoke. And in general, karaoke is not bad, except for some inconveniences associated with its management.
