The finely sculpted earbuds have been finished with beautiful metallic details on the outer face, with gold plated charging pins and snap-in magnets on the other. The same purity of design can be found in our beautiful, fabric-wrapped case.
Designed to handle whatever you or life throw at it, MOMENTUM True Wireless are made from durable, tough, splash-resistant materials.

And proven technology ensures lag-free audio and perfect synchronization between left and right earbuds (NFMI).
Take fingertip control.
Control your music, calls and voice assistant simply through intuitive touchpad technology built into both earbuds. Smart design feature means you can activate Google Assistant or Siri with a convenient single tap on the right earbud.
