Along with world renowned Sennheiser sound quality, the MB 660 features Adaptive Active Noise-Canceling technology. It constantly monitors and adapts to your background, ensuring you only hear what you want to hear.

The MB 660 is the perfect solution if you're looking to shut out the world, listen to music, or take calls (though, if you're making a lot of calls, the MB Pro by Sennheiser may be a better fit). Using the on-ear touchpad, you can naturally play, pause, change the track, and adjust volume.

If you're a bit on the introverted side, you'll enjoy the isolation of the MB 660. Hear only what's going on in your headset with earcups that completely cover both of your ears. Most people will get the message that you don't want to be disturbed, but if someone does have the nerve to approach you, you can use TalkThrough™ mode to switch off noise-canceling and tune into your surroundings without having to remove the headset.

Use Skype for Business for your calls? This version of the MB 660 allows you to take full control of your calls directly from your headset. Answer, end, reject, you know the drill – and do it all while away from your computer.
