Earphones are a pair of conversion units, which accept electrical signals from a media player or receiver, and convert them into audible sound waves using speakers close to the ears. The headset is generally detachable from the media player and connected with a plug. The advantage is that it can listen to the sound alone without affecting others; it can also isolate the sound of the surrounding environment, which is very helpful for people who use it in noisy environments such as recording studios, bars, travel, and sports. Earphones were originally used on phones and radios, but with the popularity of portable electronic devices, earphones are mostly used in mobile phones, walkmans, radios, portable video games and digital audio players.
