Developed with athletes
The adidas and Sennheiser brands are strongly associated with strong features and
utilized by sport-loving individuals and athletes. In order to offer the best audio per-
formance matched with the highest sports functionality, we have been seeking regular
feedback from athletes in crafting our second generation of sports earphones and
headsets. We prognosticate your needs and defy the harshest conditions. We under-
stand sound and sports. In the heat of competition, the sound gear must inspire and
become your source of inspiration.
