Sennheiser is bringing together the science of sport and sound with the launch of the new MOMENTUM Sport earbuds developed for athletes and sports enthusiasts.

The earbuds combine integrated heart rate and body temperature measurements in-ear sensors with unrivalled sound quality.

“We have worked for over three years to develop the ultimate sports earbuds. MOMENTUM Sport elevates earbuds from a basic exercise accessory to the heartbeat of your workout—quite literally. Now, athletes and sports enthusiasts can tap into cutting-edge fitness tech and superb sound in one device,” Sennheiser sports product manager, David Holm said.

MOMENTUM Sport integrates a photoplethysmography (PPG) heart rate sensor and body temperature sensor that can each output critical data to fitness apps and devices. The power of Sennheiser Sound is optimised for sports and supercharged with real-time performance tracking data feedback for workouts.

As the inner ear is an optimal dark location with a low degree of light pollution and one of the most stable areas of the body during physical activity, MOMENTUM Sport can offer consistent performance tracking data.

In-ear temperature readings are also more accurate than wrist-skin measurements. The MOMENTUM Sport wearer can closely monitor body temperature within +/- 0.3 degrees Celsius accuracy. Similarly, the heart rate can be observed with beats-per-minute detection ranging from 30 to 220bpm.

Integrated three-axis accelerometers plus capacitive touch and infrared sensors work in harmony to manage audio playback and call features using tap gestures. For example, a double tap of the cheek can pause a track if the wearer is using gloves.

MOMENTUM Sport’s heart rate data connects and integrates with popular sport devices and apps, such as Apple Watch/Health, Garmin Watch/Connect, Strava, Peloton and more. For the first time ever in a non-Polar product, users can enjoy full access to Polar’s elite biosensing capabilities and data analytics ecosystem by using Polar Flow as a training app.

This includes access to performance tracking, training analytics, smart coaching, and voice guidance. In-ear performance tracking data, including body temperature, are connected in real-time for instant insights during training and stored for enhanced post-training analysis.

Sennheiser’s acoustics expertise goes beyond the all-new 10mm transducer found in MOMENTUM Sport. The earbuds mitigate the occlusion effect with an acoustic relief channel that incorporates air ventilation to dramatically minimise footstep noise, breathing, and other body-borne distractions.

The semi-open design also provides natural environmental awareness to stay alert of surroundings, with additional and selectable transparency mode, anti-wind mode, and Adaptive Noise Cancelling (ANC) mode. MOMENTUM Sport operates over Bluetooth 5.2 with wide support for aptX Adaptive, AAC and SBC codecs.

The earbuds can be controlled with simple tap gestures or via the Sennheiser Smart Control app for the added convenience of an on-screen interface. Thanks to IP55 sweat and water resistance, a shock-proof chassis, and clogresistant ear tips, MOMENTUM Sport are built to withstand any workout.

MOMENTUM Sport comes with a selection of interchangeable ear fins and ear tips. The included IP54-rated carry case stores up to three additional earbud recharges, extending playback from up to six hours to 24 hours. 10 minutes of quick charging can provide up to 45 minutes of playback.

The MOMENTUM Sport is now available for MSRP of $529.95 in Polar Black, Burned Olive and Metallic Graphite.
