So, I checked more about it, and it seems that there is a splitter already provided in-box, so it will work on my pc and also found out that my 2in1 lappy has a combo jack. And supposedly, via the single cable, it should work on consoles (which I am planning to buy anyways) and phones or laptop. So I think this is the one. I would have gone for better ones, as I also realize that is the most basic version. I mean, Core is the most entry level even in the stinger series, but as I said, the other models are going pricier, even more than the conversion ratio.
Now my only query would be, that since it supports all the current gen consoles too, would it be reasonable to think that it would also work in the upcoming ones. X Box Series X ain't far away, and I intend to get that.
