Sennheiser MOMENTUM Sport True Wireless Earbuds with Adaptive Noise Cancellation (Open Box)

The rhythm of your heart ​MOMENTUM Sport integrates both a photoplethysmography (PPG) heart rate sensor and a body temperature sensor that can each output critical data to popular fitness apps and devices. It’s no secret that the right playlist can make or break a workout—a high-energy soundtrack can motivate when the finish line feels impossibly far. Now, the power of Sennheiser Sound is optimized for sports and supercharged with real-time biometric feedback for workouts that are far more efficient than a pure adrenaline approach. As the inner ear is an optimal, dark location with a low degree of light pollution and is one of the most stable areas of the body during physical activity, MOMENTUM Sport can offer consistent biometrics, even at the peak of a workout. ​In-ear temperature readings are also more accurate than wrist-skin measurements; the MOMENTUM Sport wearer can closely monitor their body temperature—within +/- 0.3 degrees Celsius accuracy—to avoid heat-related fatigue that
