Explanation:

How did they evolve with growth in technology? Back in the early 1890s, headphones were single-sided, heavy speakers that people would hold on to an ear to communicate. This later evolved into something known as an 'Electrophone'. It was a system consisting of a stethoscope-shaped headphone connected to a switchboard.
