I want my roommate to always use earbuds
Why do you want him to always use them?
I'm going to cut off his TV and other electrical gadgets. This way he will be forced to use the earbuds
It's mean to tell people what to do. You should let him listen to whatever he wants.
I'm only doing this so he stops making noise.
While I understand having a noisy roommate is annoying, it just sounds like he's not trying to be. You should be more understanding and not try to control his life.
