PC World has an article on why USB-C has not been a viable alternative for the 3.5mm audio jack. Problems with USB-C include variable handling of digital to audio conversion, incompatible SOCs inside the cable, and non-standard analog-passthrough. In short, the cables which contain computers themselves are not standardized in behavior and the author's conclusion is that mobile devices must have 3.5mm jacks until the USB-C cable technology gets sorted out enough that they become usable.

Like takyon, I am also interested in the model name/number of said device. Last cheap pair I bought was $35 and didn't do 75% of what you listed and died after three months. That thing sounds magical.
