High call quality requires excellent phone performance, where seamless professional audio makes all the difference. We further boosted the strong phone performance of our world-leading Evolve Series with three powerful professional microphones strategically positioned and by applying our high-quality digital chipset, combined with the latest signal processing technology. The result is perfect call quality, every time. In the office or on the road, background noise can be a real nuisance at work. Put on your Evolve2 65 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. In addition, our busy light is now even more convenient, because 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.
