Yes I also use brain.fm and Bose headphones, but that doesn't help this situation where all of a sudden 10 guys appear behind you and discuss about something else among themselves totally irrelevant to you. Even though I won't be able to fully hear their voices, I get distracted. Sometimes I doubt that I am very vulnerable.
