The First Ever
The first ever musical audio device was the phonograph. As a component in an audio system, a phonograph, or record player, is connected to an amplifier and loudspeakers to reproduce the sounds recorded on a record. https://school.eb.com/levels/middle/article/phonograph/276406 -
The Gramophone
In 1887 Emile Berliner patented the Gramophone, a phonograph that traced sound grooves on a flat disc rather than on a cylinder. https://school.eb.com/levels/middle/article/phonograph/276406 -
The Microphone
The first commercial electrical recordings were made in 1925. Microphones were used to transform the sound into electrical signals, which operated the cutting stylus. The electrical phonograph—using essentially the principles employed in the modern phonograph—was introduced at about the same time. https://school.eb.com/levels/middle/article/phonograph/276406 -
Stereo Discs
In 1958 the first commercial two-channel, or stereo, discs were introduced. They held two separate channels of sound in a single groove. Stereo recording produced better-defined sound, with a greater sense of space and dimension. https://school.eb.com/levels/middle/article/phonograph/276406 -
The Cassette Tape
The cassette, essentially a miniature reel-to-reel mechanism in plastic or metal case, was introduced in 1964. By the 1970s cassettes had become capable of high fidelity, and by the early 1980s the sales of music cassettes exceeded those of phonograph records. https://school.eb.com/levels/middle/article/tape-recorder/277268 -

Spotify
Before streaming services came along you might have been guilty of using controversial file sharing sites like Napster, LimeWire and The Pirate Bay to download your music. "I realized that you can never legislate away from piracy," Daniel told The Telegraph in 2010."The only way to solve the problem was to create a service that was better than piracy and at the same time compensates the music industry." -
Bluetooth Ear buds (Wireless Device)
Wireless headphone that fits inside your ear and can connect to any device with Bluetooth. Wireless earbuds have become increasingly popular as consumers move past their wired predecessors. Such earbuds are portable speakers that fit inside people’s ears and connect to any audio-producing device (e.g., a phone or computer) using Bluetooth audio technology. Wired earbuds, by contrast, use a cable to attach to devices that have an input jack. -
Brain Powers!?
In the future, around 2075, I think we will be able to choose a song on our device with our minds. You still have to have a device playing music, but you can choose the songs by thinking of it in your mind.
