Noise reduction headset usage scenarios
1. Commute to work or on buses, trains, and airplanes: wear noise-cancelling headphones to sleep quietly, or wear noise-cancelling headphones to enjoy music and movies with a lower voice (if you don’t have noise-cancelling headphones, you need to turn on the music very much Loudly overshadow the sound of the engines of cars and airplanes, and over time it will inevitably damage hearing).
2. The children went to the tutoring class, parents waited outside the tutoring class classroom, a group of people chatting is very lively: put on noise-cancelling headphones, without any interference, wait for the children to listen to music and play games after class
3. University dormitory, a group of students playing games loudly: don't want to play games, want to study and study quietly without interruption, just put on noise-cancelling headphones.
