The headphones were on. They had been utilized on purpose. She could hear her mom yelling in the background, but couldn't make out exactly what the yelling was about. That was exactly why she had put them on. She knew her mom would enter her room at any minute, and she could pretend that she hadn't heard any of the previous yelling.

Sometimes we use headphones not just for music, but to create a barrier between ourselves and the outside world. It's a way to protect our peace of mind and give ourselves a moment of solitude. In this case, the headphones serve as a shield from the chaos happening outside the room.
