Sound Leadership – Adaptive Active Noise Cancellation
Focusing on your work without being disrupted or distracted by your colleagues or other sources of noise has become a serious challenge in an open office environment. Sennheiser?s NoiseGard? hybrid adaptive active noise cancellation technology constantly monitors the background environment for ambient noises and adjusts the level of noise reduction in your headset. This unique technology enables you to take control of your sound environment so you can have a productive, disruptionfree workspace.

Business-grade communication SpeakFocus? 
Striving to be heard in a noisy environment can make communication inefficient and stressful. And in business, clear communication is crucial. SpeakFocus? technology, with 3 digital microphones, delivers crystal clear sound, making it easy for listeners to hear what you?re saying ? even in noisy open offices, so your call time is always effective.

Advanced Own-Voice-Detector
Reducing background noise doesn?t mean compromising on the quality of your own voice. Sennheiser?s Advanced Own-Voice-Detector continuously monitors the environment to determine whether your voice is present or not. When your voice is detected, it reacts immediately to provide optimal speech intelligibility while simultaneously reducing background noise.

WindSafe?
Windy days can be a call killer when conversations need to take place outdoors. Sennheiser WindSafe? technology ensures the clearest possible sound is sent to your listener by reducing wind noise using advanced digital signal processing, combined with a specially designed wind screen ?rosette?. Because wind passes by without causing turbulence, your voice is easily heard, without background disturbance.

Sennheiser signature sound
Relaxing between calls is an effective way to reduce stress during long, busy workdays. To get the best, personalized sound for speech, music and entertainment from your headset, MB 660 UC delivers Sennheiser?s respected high-quality stereo audio, and CD-quality streaming with aptX?. With a choice of sound effect modes (Club, Movie, Speech, Director), you can create your own personalized sound profile.

Quality design – Sennheiser craftsmanship
Looking good is important in business and the MB 660 UC represents the best in quality materials and comfort. Discreet and elegant use of polished and brushed metals and fine, soft leather ear cups combine with a compact and foldable design for portable style and maximum comfort. Its built-in microphones maintain the streamlined style. You can expect the best in both performance and comfort with the MB 660 UC.
