Background

Earphones (ears; heads-sets; ears) are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers near the ears. The headset is typically detachable from the media player and utilizes a plug connection. The advantage is that the user can listen to the sound independently without influencing other people; can also isolate the sound of the surrounding environment, and is very helpful for people who use in noisy environment such as recording rooms, DJ, trips, sports, and the like. The earphone is originally used for telephone and radio, but with the prevalence of portable electronic devices, the earphone is often used for mobile phones, walkmans, radios, portable electronic games, digital audio players, and the like.
