Put on your Evolve2 40 and feel the noise disappear immediately, as soon as the oval insulating cushions and the new angled earcups effectively block out your surroundings through passive attenuation unlike anything you have experienced before. Our busy light is now even more convenient as it is visible from all sides. The red light turns on automatically when you are on a call or in a meeting. You can also turn it on yourself at the touch of a button. So if you are busy, everyone sees that immediately and you can continue undisturbed. Satisfaction isn't often guaranteed these days, but we're starting again: the Evolve2 40 works on all major Unified Communications (UC) platforms for truly seamless collaboration.
