Bose headphones are a family of headphone products sold by the Bose Corporation. The company was a pioneer in the development of headphones that use active noise cancellation technology.

Like all such technology, it mixes an inverted sample of the ambient sound outside the headset with the sound that reaches the inside of the headset, partially cancelling out the noise. Active (battery-powered) noise cancellation is never perfect, and is better at low frequencies than at high frequencies.

As with all active noise cancellation technologies, it requires a source of power, a small battery inside the headset, to perform the cancellation.
