السلام عليكم ورحمة الله وبركاته احسن الله إليكم I work at an office where they play music. I try to make them turn it off, but instead they just lower it . Am i sinful for working here and is my money halal. I do wear noice cancelling headphones

No you are not sinful and you can't control people. And you did the right thing by blocking out the sound. Your salary is halal, don't fall into waswas.
