@@JZM006 no, the mics not fine. It sounds as if either he has a bad connection in one of the wires or his mics trying to pick up his voice but mistaking it for background noise (a lot of mics now block out background noise) or one thing is his mic sensitivity is all out of wack
Perhaps you could've made the whole controller yellow, then have the triggers and bumpers blue and the sticks and dpad pink to follow the colour orientation of the logo.
Rather than getting a new mic, try staying a consistent distance from it. It sounds like your earbud mic is swaying back and forth. If that's all you have, that's cool! Everyone starts somewhere! But since it seems you dub these over after recording the video anyways, holding your mic in place and/or keeping your head still will help a lot with audio quality.
