Sennheiser Momentum Sport Noir

The Sennheiser Momentum Sport are the new flagship sports headphones from Sennheiser and offer top-notch sound quality, a reliable fit for any activity, and novel features in the shape of heart rate and body temperature tracking. However, they are more expensive than the best sports headphones from Bose, Jabra and Apple, and the heart rate tracking has been inaccurate during my testing.

The Sennheiser Momentum Sport, featuring innovative Polar sensors, delivers exceptional sound quality and tracks heart rate and temperature. Its waterproof design and user-friendly app enhance the workout experience, and though it isn't a replacement for wrist wearables, the buds offer unparalleled comfort and functionality, making them a worthwhile investment for fitness enthusiasts.

The ultimate earbuds for athletes cost a pretty penny.

Over the past 20 years, I've tried nearly all top-tier earbuds available, and I possess a solid background in sound engineering. While I won't make comparisons to other earbuds, I will share my candid thoughts. Pros: 1- The sound quality is excellent across all sound ranges. 2- They have a sleek, sporty appearance. 3- Not sure why concerns about not fitting well in comments; with the earfins and eartips provided, they stay securely in place. Cons: 1- The case is quite large, making it impractical for pocket during runs or walks. 2- Differentiating between the left and right earbuds isn't intuitive; you must look for the L and R markings. 3- The charging case emits noise during wireless charging, an issue experienced with four different charging pads. 4- After calls, random disconnection problems occur.

I like the sound. It is close to the Bose quality. I really like that it measures the heart rate and body temperature. The fit is such I can wear them to bed.
