Ear buds/Earphones

Ear buds or earphones are headphones of a smaller size that are positioned directly outside of the ear canal, but without fully enveloping it. They are generally inexpensive and are favored for their portability and convenience. However, due to their inability to provide isolation, they are not capable of delivering the same dynamic range offered by many full-sized headphones and canal phones for a given volume level. As a result, they Are often used at higher volumes in order to drown out noise from the users surroundings, which increases the risk of hearing-loss.
