Put on your Evolve2 40 and feel the noise disappear immediately, as soon as the oval insulating cushions and the new angled ear cups effectively block out your surroundings through passive attenuation like you have never 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 is not often guaranteed these days, but we're starting again: the Evolve2 40 works on all major Unified Communications (UC) platforms for truly seamless collaboration.
