A pair of conversion devices known as earphones, headsets, or earpieces uses speakers located next to the ear to transform radio signals from a media player or receiver into audible sound. The media player and earphone are separable, and the only way to connect them is with a plug. It won't disturb people when it listens to the sound by itself. In addition, it has the ability to muffle outside noise, which is highly useful for those who frequent busy places like clubs, recording studios, travel, and sporting events. Originally designed for use with phones and radios, headphones are now being used with digital music players, walkmen, mobile phones, and portable video games due to the growing popularity of portable electronics.
