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. Sennheiser's OCX 686G was created to energize your music so you can concentrate on sets and reps. New high-output drivers deliver amazing sound quality. Innovative ear-canal coupling and behind the ear cable routing work together to reduce unwanted background noise so you can enjoy your favorite music without distractions. The lightweight, ergonomic design ensures a comfortable fit while the ear hooks provide extra hold providing maximum freedom of movement during your workout. Sennheiser's OCX 686G lets you focus on achieving your personal best performance each and every time. They're the best training partner you'll ever have!
