Earbuds

Earbuds are like headphones in a smaller foot-print, made out of hard plastic or wood material. These are usually fit on the concha ridge at the center of ear canal. Earbuds uses large drivers as compared to the earphones which results in not so good fit but provide better sound-stage since they don't seal your ear canal the way earphones do. Noise isolation is not so good in ear buds but in return they provide much better sound-stage.
