Sennheiser's new SPORTS headsets are the perfect fusion of sound, performance and ergonomic design for people with a passion for sport. Six models were developed in conjunction with commissioned university studies researching the impact of extreme movement on sound, comfort and fit. High tech materials were carefully selected to maintain comfort, water resistance, durability and hygiene. New drivers were developed to deliver excellent energizing sound. Oval cables are employed to significantly reduced noise. All models include an integrated smartphone remote and microphone allowing for easy control of volume, tracks and calls when exercising. Combining innovative design and impressive sound quality, Sennheiser's MX 686G is the perfect companion for long runs on the open road. The clever Slide-to-Fit mechanism ensures that these earphones sit comfortably and securely. New high-output drivers deliver dynamic sound to inspire to push for the extra mile. The MX 686G will also help you to reach the finish line safely, since its open design allows you to hear surrounding traffic noise. Stay in step and stay alert with the MX 686G!
