These are the high-performance ear buds for iPhones and other smart phones that never need to be untangled before you plug them in. Unlike standard issue ear buds, the entire length of the ear buds' 55" cord is surrounded by a braided nylon sheath that won't become snarled when placed in a pocket or purse. Two 9mm Neodymium drivers with a 20,000 Hz frequency response deliver rich, full-range acoustics for a listening experience unsurpassed by competing models. A patented integrated microphone permits convenient hands-free conversations and lets you pause/play music. Made from lightweight aluminum alloy, each earphone is individually milled to precise specifications and polished to a high gloss. Its gold-plated plug fits iPhones, iPods, or any device with 3.5mm audio output. Three sizes of silicon ear seals are included to ensure a comfortable fit. (2 oz.)
