The new MOMENTUM On-Ear Wireless

The new Sennheiser MOMENTUM On-Ear Wireless provides complete freedom to experience your music like never before. It combines high-resolution sound with a lightweight, puristic design and exclusive materials like stainless steel and Alcantara®.

Without the limitations set by a cable, but with the same crystal-clear sound.

Brilliant and vivid

Thanks to the interaction between the hybrid active ® NoiseGardTM noise reduction and the high-definition aptX codec every nuance in sound is carved out in even finer detail. Being an integral part of the headphones, the VoiceMax microphone enables you to conduct crystal-clear conversations without the need of an external microphone.

Experience a whole new quality in wireless sound. Our MOMENTUM On-Ear Wireless headphones provide High-Resolution sound, with a powerful bass - and without the cable.

Puristic and durable

The new MOMENTUM On-Ear Wireless not only excels with improved sound but also with its revised design. The slightly curved profile of the headband as well as high-class materials like breathable Alcantara® make for enhanced wearing comfort.

Puristic and durable

Comfortable and variable

The ear cups of the new MOMENTUM On-Ear Wireless are attached to highly mobile ball joints running in collapsible sliders. The result: The headphones fit perfectly, also in their new space-saving carrying bag, thanks to the collapsible design.

Headband and ear cushions of the MOMENTUM On-Ear Wireless are covered with super soft, breathable Alcantara®. For still more wearing comfort the ear cushions are filled with special two-layer foam.

Comfortable and variable

Optional and optimized

The new MOMENTUM On-Ear Wireless can also be operated with a cable, just like any conventional headphones. The design of the jack plug, however, is not conventional at all: Its especially low profile was optimized for the use on mobile devices.

Fitted with jack plugs on both ends, the cable is completely detachable and can be replaced if necessary.
