Ultra-lightweight in-ear headphones from iSINE series that are a one step up from the iSINE 10 model, featuring an even longer Uniforce voice-coil that covers the ultra-thin diaphragm to a greater extent, enabling better control and responsiveness for better bass, clarity, and improved imaging. They barely weigh 20 grams and contain all of the Audeze's exclusive patented technology including power enhancing high-grade neodymium Fluxor Magnets that nearly double the magnetic driving force on the large, ultra-thin planar 30mm diaphragms with patented Uniforce voice-coil technology that delivers the most accurate in-ear headphones experience ever. The distortion (THD) is less the 0.1% overall even at high volumes, an amazing achievement for in-ear headphone designs. Included 1.5m long Audeze's award-winning CIPHER Lightning cable specially optimized for the iSINE series delivers 24-bit digital audio from iPhone/iPad/IPod to the headphones.
