The Sennheiser MX 686G SPORTS is the perfect companion for long runs on the open road, or those high intensity work-outs. The clever Slide-to-Fit mechanism ensures that these earphones sit comfortably and securely. The eartip design is not as obtrusive as a typical in-ear, but fits more securely than a standard earbud. The MX 686G SPORTS will also help you to reach the finish line safely, since its open design allows you to hear surrounding traffic noise. Microphone and volume controls for Apple and Android devices. Plus the MX 686 headphones are moisture and sweat resistant! Full 2 year warranty from Sennheiser.
