Why does my fifine AM8 sound worse than the A6?

A few days ago I received the AM8 that I ordered on Aliexpress, I was very excited to try it and start recording content (I make commented videos on YT about certain topics) the thing is that when I started testing it I realized the terrible audio quality it has, unlike the A6 that I had bought at the beginning of this year, this one sounded much better, clear, without noise or interference or static sound, it was obviously a condenser microphone, I bought the AM8 after watching endless videos and Everyone is talking wonderful things about it, I even preferred it over the Maono, but when I tried it I ended up being disappointed, that's why I came here to find out if anyone had the same experience, maybe I'm doing something wrong, maybe my problem is my PC or possibly it's a defective unit, I would like to know your opinions, if you have any questions about the case, ask me so I'll give you more information.
