All headphones generally tend to dampen ambient noise - more or less. But sometimes this passive way of stopping intruding sounds is not enough: especially in busy places or on planes and buses. That's where Sennheiser's own NoiseGard® technology works its magic. Plainly put: It recognizes the noise and sends out an opposite signal - a negative to the positive – thus neutralizing the noise, so it doesn't interfere with your favorite tracks.
Sennheiser offers a range of noise-cancelling headphones - some also with Bluetooth® technology on board - in different price segments.
