I have never heard of this DD-hifi brand. I bought this USB A-C cable for testing purposes, to see if it would show something different, maybe better sound. I have not experienced any different or better sound between USB A-C cables between my media player and SSD drive till now. True, I have not tried a big high-end brands. In this case, this DD TC07AC cable sounds different at first listen, and in my opinion, with a better instrument representation than the AudioQuest Carbon A-C cable I have been using here so far. If burn-in also matters here, then maybe it will get better.
