Earphones (Headphones; Head-sets; Earpieces) are a pair of conversion units that receive the signals emitted by the media player or receiver and convert it into audible sound waves using a speaker close to the ear. The headset is generally detachable from the media player and is connected using a plug. The advantage is that you can listen to the sound alone without affecting other people. You can also separate the sound of the surrounding environment and help those who use it in a noisy environment such as recording studios, DJs, trips, and sports.
