PXC 480
You cannot always control the sound of your environment. But with the PXC 480 you can control if and what you will hear from it. Featuring Sennheiser’s NoiseGard™ Hybrid noise cancelling it will let you enjoy your favorite music even in the noisiest of surroundings. And it has another special treat in store: When you are not listening to music, NoiseGardTM can be used in passive mode to create an oasis of calm, by simply detaching the cable.
