I'm not sure of the exact year, but I would say at the same time Edison invented the gramophone recording device. Ear phones are nothing more than transducers--such as a microphone, a telephone mouth piece or ear piece, etc. A transducer takes electrical impulses and turns them into sound waves, or the reverse--it takes sound waves and turns them into electrical impulses. The first recording devices were not able to record very loudly, which is why you see the gramophone with the big speaker--to amplify the sound. Initially, Edison would have used ear phones instead of big gramophone speakers.
Probably the first headphones were invented sometime in the late 1870s for telephone operators so that they could easily hear the caller while many other operators in the same room were talking.
But the largest early usage of headphones (and when the general public first encountered them) was on early homemade crystal radio sets in 1904.
The usual person credited with the invention of headphones is Nathaniel Baldwin who built his first pair of audio headphones on his kitchen table in 1910.
But there were clearly others using similar devices earlier as photos of telephone exchanges from the early 1880s show operators wearing electrical listening devices on their heads and crystal radios introduced in 1904 cannot be heard without something like a headphone.

auriculares is the spanish word for headphones or earphones
There are two syllables in the word 'earphones'.
I could only imagine that they were invented with the purpose of being innovative and appealing to people who want more portability, light weight, and less standing out from the traditional bulky headphone.
