Answer:
Let's take a look at the modern day headphones we have now. They're airpods. Wirless. It used to be connected to wires. And those earbuds used to be headphones. And those headphones used to be heavy speakers.
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.
We started using them in the wars to communicate with the troops on the ground and now we use them to stay focused, to disappear and to give ourselves some time away from the stressful world we live in.

My answer:
Despite the fact that everybody realizes that seawater is pungent, not many realize that even little varieties in sea surface saltiness (i.e., convergence of broke down salts) can effectsly affect the water cycle and sea flow. Since Earth's commencement, certain cycles have served to make the sea pungent. The enduring of rocks conveys minerals, including salt, into the sea. Dissipation of sea water and arrangement of ocean ice both increment the saltiness of the sea. Anyway these "saltiness raising" factors are ceaselessly offset measures that decline saltiness, for example, the nonstop contribution of new water from streams, precipitation of downpour and day off, liquefying of ice.
