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.
