Sennheiser PXC 450 features an updated version of the NoiseGard technology (2.0) which actively removes up to 90% of unwanted background noise. If someone speaks to you while you’re wearing these you can push the talk-through button and the headphones will let the speech get through and still filter out unwanted noise.
The NoiseGard technology is powered by two AAA-batteries (no batteries = no NoiseGard, you’ll still have functional headphones), there’s control buttons on the side for volume adjusting and yes, they’re foldable.
“NoiseGard™ is an active noise compensation system which Sennheiser originally developed for use by pilots, who have to rely on good sound quality and efficient protection against ambient noise even in high-noise environments. NoiseGard™ actively compensates the noise, based on the physics principle of sound and counter-sound.
