đàn ghi ta, guitar Hero: Metallica - Impossible Vocals?

Well, I, personally, haven't played GH Metallica period. However, I CAN answer the problem with your "unresponsive headset". See, bạn KNOW that your hát correctly but the game thinks otherwise, then all bạn need to do is calibrate it. Somewhere in the settings menu there should be an option to calibrate the microphone. I'm not %100 sure if there IS one for GH Metallica (as I đã đưa ý kiến before, I don't own the game), but just look and make sure. I also recommend getting a USB microphone (any will do), but that little headset isn't going to cut it. And I know. I've used it before with Rock Band and it's as unresponsive as my dog.
