Whenever I broke my brother's headphones I returned them.
Why did you break them?
I have no interest in listening his latest Death Metal band and I told him so before breaking them
That was your brothers and something that he really liked. You need to replace it and you should be more careful next time not to break family's things.
I don't have to listen to his music and he can go buy another pair if he wants to.
When he buys another pair you'll just hear the same music, so what was the point? You shouldn't break things that belong to your family because that could be rude. You should buy him a new pair for breaking his old ones.
