Luscious listening. This earphone is the smallest member of the MOMENTUM product family. Still, it offers uncompromisingly clear, brilliant and powerful sound like all MOMENTUMs, as well as a wealth of valuable quality details - from the ultra-precise, stainless-steel sound tunnel to the three-button multifunction remote with integrated microphone. The true dimensions of the Sennheiser MOMENTUM In-Ear headphones can be measured not only by their uncompromising sound but also in a wealth of little details - from the ultra-precise, stainless-steel sound tunnel to the three-button multifunction remote with integrated microphone. Features and Benefits Sleek and sophisticated - The design of the MOMENTUM In-Ear speaks a clear, consistent language. Comes with a stylish black-lacquered zipper on the soft-covered case that safely protects your earbuds. The black cable leads to a chrome housing. And the outstanding design also extends to their fit, with comfortable tips that sit just right. Brilliant and powerful - There’s only one way to deliver uncompromising sound in a small package: by combining top-quality materials with superior craftsmanship. That’s why the acoustic components contain no plastic. They are made of high-quality stainless steel, manufactured using precision milling technology. It’s not a difference you can see - but one you’ll hear in the powerful yet nuanced sound signature. Adaptable and ergonomic - You can forget about the MOMENTUM In-Ear. With their ergonomic, adjustable angle of 15°, the buds adapt so well to your ears that you’ll forget they are there. Thanks to the extra-small sound tunnel and a choice of four ear sleeves to fit any size ear, all you’ll experience is the pure sound. Functional and durable - The range of In-Ear accessories is as broad as the In-Ear itself is tiny. Including a sturdy hard-shell case, intuitive remote, elliptical cable that minimizes tangling and sound loss, gold-plated jack and integrated hands-free microphone.
