Who knows Nathaniel Baldwin

Nathaniel Baldwin was the inventor of an improved telephonic earphone, amongst many other inventions, and a supporter of the early fundamentalist movement Baldwin then worked at remote hydroelectric plants at the Snake Creek near Heber City and in East Mill Creek Canyon.   

was also electrician and air compressor operator while he experimented with sound amplification using compressed air. He used this to invent more sensitive receivers, which he made into the first modern headphones in 1910 and sold to the U.S. Navy. His first ones were made by hand in his kitchen and, despite the Navy's suggestion, never patented because he considered their invention "trivial."

hear phone . 1895 – Thanks to the Electrophone system, in 1895 folks could start rocking out to the sick beats of the local opera house from the comfort of their own home. Subscribers to the pricey service would listen through headphones that looked more like stethoscopes than a modern offering as very large people produced very big sound on a stage miles away. 

1910 – Nathaniel Baldwin began manufacturing the first modern headphones. He crafted them in his kitchen and sold them all to the U.S. Navy. This was the first time a pair of cans resembled something you’d see today. Baldwin never patented them, however, because he was an idiot. 

In 1914, Baldwin started a business in East Millcreek, Utah called The Baldwin Radio Company. He powered the plant and the neighborhood through a hydroelectric generator which he made out of bicycle wheels and piano wire. The company peaked at 150 employees and $2 million in annual sales in the 1920s. One legend tells that Philo Farnsworth built his first television in Baldwin's factory.

2001 – The iPod changed up the whole music universe. It became common to see people with a white cord running from their pocket to their ears multiple times a day. From their inception in 2001 to today, over 300 million iPods have been sold all with the accompanying pair of earbuds.
