Headphones have come a long way since the electrophone was invented in Britain in 1895, allowing subscribers to listen to live musical performances over phone lines. Today, Americans typically spend more than 32 hours weekly listening to music, almost equivalent to a full-time job.

Seventy-eight percent of people say music improves their productivity at work, and 46% of people wear headphones at work to avoid conversation. This infographic outlines the history of headphones and explains the productivity benefits of using headphones at work.
