Get to know this product.

MB 660 UC MS is a wireless, Skype for Business Certified, adaptive ANC headset designed for knowledge workers demanding business-grade communication and premium Sennheiser sound quality for maximum productivity in open offices.

NoiseGard™ hybrid adaptive ANC

  • By constantly monitoring your background environment for noise, Sennheiser’s NoiseGard™ hybrid adaptive ANC technology seamlessly 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, disruption-free workspace.

UC certified business-grade communication

  • Business-grade communication voice clarity is key to success in every organization. The MB 660 wireless and wired solution in one deliver a certified, business-grade communication experience, whichever your UC environment might be.

Sennheiser signature sound

  • Create your own sound with a choice of sound effect modes, to get the best personalized sound for speech, music and entertainment. The MB 660 delivers stereo audio, and CD-quality streaming with aptX® in Sennheiser’s renowned high-quality, for your ultimate sound experience.

Reclaim your office

  • We haven’t compromised on a single detail with the MB 660 series. In addition to taking noise cancellation to the next level and delivering the renowned Sennheiser signature sound, the MB 660 Series has been designed to be the ultimate business tool for maximizing your productivity.


  • Sennheiser’s unique 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

  • When you are in a conversation, the Advanced Own-Voice-Detector detects your voice and optimizes speech intelligibility as well as reduces background noise for your listener. When no speech is detected, all distracting background noises such as keyboard- or paper rustling sounds are gradually reduced to make the communication experience more enjoyable for the listener.


  • Be sure that your message gets through – even in challenging outdoor environments. WindSafe™ technology reduces wind noise to ensure the clearest possible sound is sent to your listener – and that your answers aren’t left blowing in the wind.

Room Experience™

  • By externalizing the sound from your head, Room Experience™ gives you the impression that you are having a conversation with a person in the same room. This more realistic sound gives you a more natural and comfortable listening experience during a call.


  • With Sennheiser TalkThrough technology, you can listen to your colleagues or keep an ear open for flight/train announcements – all without removing your headset.

Touch pad

  • Call & media controls direct from the touch pad: answer/end call, reject, hold, mute/unmute, redial; play/pause music, change track, volume up or down

Pillow-soft leather ear pads & ear-shaped ear cup design

  • Premium quality material to ensure maximum comfort, ergonomics and style.

Battery time

  • MB 660 UC features up to 30 hours of battery time. Even if it runs out of battery, you can still enjoy using the headset with the included audio cable.

Folding & Storing

  • Easy on/off by turning the ear cups. Foldable design for compact storage.
