The office workers who squeeze the subway every day are probably used to the noise in the subway

First, business people. Because of frequent business trips, especially business people who commute between different cities every day, they must hate the noise in the cabin. If there is a noise reduction headset, they must be able to stay away from the noise and relax by listening to music.
Of course, there are also subway people. The office workers who squeeze the subway every day are probably used to the noise in the subway. However, if they can have a pair of noise reduction earphones at this time, they can not only stay away from the noise, but also adjust their mood through earphones and enjoy the process happily.
Office workers also need a pair of noise reduction headphones. Sometimes when thinking about the planning scheme, it is very annoying to hear the voice of the central air conditioner running, and it is even more annoying if there are colleagues around who keep whispering. At this time, you may as well wear a pair of noise reduction headphones to expand your thinking in the beautiful music.
