Amazing Comfort and Fit Boasting the exact look and feel of the Image S4, this for-Android headphone features patented oval ear tips that ensure hours of comfortable, long-term wear. Unlike circular-shaped ear tips that put stress on the pressure points inside the ear, Klipschs patented oval ear tips naturally fit the contours of your ear canals, providing comfortable long-term wear. These ear tips also offer superior noise isolation (or passive noise-cancellation), blocking out almost all ambient noise and providing excellent bass. Premium Sound Equipped with a dual magnet 8.5mm driver, the Image S4A covers a wide frequency range, while delivering dynamic detail for the most strikingly realistic sound reproductions of beloved music libraries. The Image S4A requires download of the free Klipsch Control app for full functionality. Once installed, the headphone instantly becomes a fully functioning headset. With its single-button remote, users are able to play, pause and skip music tracks, answer and end incoming calls, and voice search. Each of these button functions can be customized with the Klipsch Control app. By simply assigning the one-, two- or three-click functionalities of the remote to the different call and music controls, you are granted a customized listening experience each time you plug in.
