Need help in Sensory Overload

I was told basically to shut it up and deal with the loud noises I need help with dealing with them. Does anyone have any good options on noise cancelling headphones. I use galaxy buds but it isn't enough. I need something to tune out the max volume of an iPhone and a television combined plus a sound bar on maybe volume level 28-32. Also what would be useful to use while sleeping. I am in kind of a desperate situation right now. Please and thank you.
