Information on Closed Last Updated: 11.08.07

Closed headphones have a sealed backing, which attenuates soundwaves propagating in the direction away from the ear. As a result, listeners away from the headphones cannot hear the produced sound easily. In addition, sound from outside is attenuated by the sealed backing, providing a level of isolation to the listener (typically a 10 dB decrease in outside sounds). A sealed chamber generally has the added negative effect of distorting sound in certain instances and providing "boomier", less controlled bass, making them lower in price and high-end quality than open headphones.
