he new Sennheiser MOMENTUM Wireless lets you experience crystal-clear MOMENTUM sound without being attached to a cable. It combines high-resolution sound with a lightweight, puristic design and exclusive materials like stainless steel and real leather. While the hybrid active NoiseGardTM attenuates ambient noise, the high-definition aptX codec carves out every aural nuance in even finer detail. Thus, the trademark MOMENTUM sound becomes still more brilliant. Furthermore, the VoiceMax microphone, as an integral part of the headphones, enables you to conduct crystal-clear conversations without the need for an external microphone.
