About Headphones Function

The headphones are small speakers which you use close to your ear to listen music. These small transducers are available in four forms among which the earphones are the most common ones. The ear buds or earplugs are the most popular ones among them due to the increasing use of iPods and MP3 players.

These different forms differ in shape and size. They work in the same manner as the speakers. Only difference is the size. Speakers or loudspeakers are very large in size and can play the music which everyone can hear. The headphones are for more personal use. The headphones move the air in the ear canal so that you can hear the music.

Headphones come as open back and closed back headphones. The open back headphones are open at the back and thus the sound escapes outside and everyone in the room sitting next to you can hear it. While the closed back headphones are closed or have a seal band at the back therefore, the sound cannot escape and you are to only one who enjoys the music.
