Noise-canceling technology gives you peace and quiet
Sennheiser's NoiseGard 2.0 technology reduces extraneous sounds by up to 90%, such as engine roar, wind noise, and the conversation of surrounding passengers. Tiny microphones in the headphones pick up the sounds of your environment. Advanced circuitry then creates a signal that "cancels out" much of this external noise without affecting your music or phone calls. A handy "TalkThrough" function lets you temporarily override the noise canceling circuit with the push of a button to carry on a conversation with a seatmate.
Exceptional comfort, sound quality, and convenience
The MM 550's earcups feature plush leatherette cushions that feel great. Plus, their around-the-ear design helps further seal out distracting noise while taking pressure off your ears. An adjustable padded headband ensures comfortable listening for hours on end, making these 'phones ideal for long trips. The headband conveniently folds up for easy storage when you travel. Sennheiser's patented Duofol diaphragms deliver detailed, crystal clear sound, while a selectable audio enhancement feature provides added depth and excitement to your music on demand. And just in case you need it, Sennheiser includes a cable plus an airline adapter for a direct wired connection in situations where Bluetooth is not permitted, or you want to make use of in-seat entertainment and other wired sound sources.
