The Sennheiser MOMENTUM Sport True Wireless are a long-awaited update to the comparatively pared-back Sennheiser Sport True Wireless earbuds. They're also the first headphones in collaboration with the fitness tracker company Polar. Signaled by the 'MOMENTUM' moniker reserved for the brand's flagship releases, these sport not only active noise cancelling (ANC) (absent on the previous sports buds) but also Polar's sensors to help you to track your athletic performance. So, are these the best picks for the long run?
Our Verdict
The Sennheiser MOMENTUM Sport are decent for neutral sound. Their default sound profile is warm, with vocals that have somewhat veiled detail. The companion app includes a five-band EQ that you can adjust to your taste. Their aptX Adaptive (High Quality) also transmits higher-resolution audio. However, they're a bit finicky about in-ear placement, which can lead to less consistent audio delivery between wears.
- Comprehensive in-app EQ and sound settings.
- Multi-device pairing and wide Bluetooth codec selection.
- Somewhat short continuous battery life.
- Finicky frequency response consistency.
The Sennheiser MOMENTUM Sport are good for commuting and traveling. They're comfortable with different ear stabilizers to choose from alongside ear tips to suit your anatomy. Their combined ANC and passive isolation do a good job of cutting down on noises like engine rumbles, traffic, chatter, and sharp brakes. You can access most of their controls at your fingertips, while the app offers quite a lot of flexibility, including 'Eco' mode, which extends battery life. On that note, their continuous battery life is enough for commutes, but it won't last through long international flights without taking breaks to use their charging case.
- Comfortable and very stable fit.
- Good combined noise cancelling and isolation.
- Comprehensive in-app EQ and sound settings.
- Somewhat short continuous battery life.
The Sennheiser MOMENTUM Sport are excellent for sports and fitness. Thanks to their selection of stabilizers and ear tips, they'll stay in your ears when exercising. All the controls you need are easily accessed through the touch controls, and the earbuds and case are water-resistant. For exercising outdoors, you can adjust the transparency mode's mix or increase the ANC to focus at the gym. Although it's not the strongest noise cancelling, it's still rather good. Outside of that, the earbuds have biometric monitors you can sync within the app or add to the Polar app. That said, their continuous battery life is on the shorter side.
- Comfortable and very stable fit.
- Biometric monitors.
- Earbuds and case have water resistance.
- Somewhat short continuous battery life.
The Sennheiser MOMENTUM Sport are decent for office use. They're comfortable without feeling too invasive and won't disturb your coworkers with sound leakage. They do a good job of blocking office noises, but you might hear the murmurs of chitchat from time to time. Equipped with multi-device pairing, you can switch between your phone and office PC easily. Plus, they're very well-built. Unfortunately, their continuous battery life won't make it through the workday, so you'll need to occasionally pop them back in the case to recharge.
- Comfortable and very stable fit.
- Good combined noise cancelling and isolation.
- Multi-device pairing and wide Bluetooth codec selection.
- Somewhat short continuous battery life.
- Finicky frequency response consistency.
- Mic struggles with background noise.
The Sennheiser MOMENTUM Sport aren't suitable for gaming. They're Bluetooth-only earbuds, which limits the gaming devices they'll pair with. They have the aptX Adaptive (Low Latency) codec, but it's still not low enough latency to match up perfectly with your games.
The Sennheiser MOMENTUM Sport are Bluetooth-only earbuds and don't have a wired connection.
The Sennheiser MOMENTUM Sport are decent for phone calls. Their microphone system records your speech, sounding mostly true to life, though it struggles with rejecting background noise. As a result, in loud spaces, your words can cut out, or the caller will hear a fair amount of your environment at the same time. Still, their touch controls and multi-device pairing mean you can easily navigate calls.
- Comfortable and very stable fit.
- Multi-device pairing and wide Bluetooth codec selection.
- Somewhat short continuous battery life.
- Mic struggles with background noise.

Popular Headphones Comparisons
While the Sennheiser MOMENTUM Sport are unique in that they have biometric monitors for your heart rate and body temperature, which you can view in the Smart Control app or use in concert with more nuanced fitness functions in the Polar app, they otherwise share a lot in common with the Sennheiser MOMENTUM True Wireless 4. They sound pretty similar with the same Bluetooth codec compatibility. Still, they're less invasive and more stable fitting with a greater IP55 rating than the MOMENTUM True Wireless 4, which, on the other hand, supply better noise cancelling and longer continuous battery life. It really depends on whether the biometrics, fit, and durability outweigh ANC and battery life when choosing which buds to take on your run.
Still, if you want to check out the best noise cancelling earbuds, the best wireless earbuds for running and working out, or the best-sounding wireless earbuds, we have some suggestions you can compare.
Although geared towards sports, the Sennheiser MOMENTUM Sport share common ground with the Sennheiser MOMENTUM True Wireless 4, including similarly warm sound profiles and the same Smart Control app with ear stabilizers. However, the MOMENTUM Sport have a more durable silicone case, greater water and dust resistance, and their fit feels less invasive. Plus, the MOMENTUM Sport have biometric monitors, which are unique to the earbuds and synchronized in the app, but arguably, if you have a fitness watch, some of those bases are already covered. On the other hand, the MOMENTUM True Wireless 4 boast a longer battery life to get you through a workday or commute and more effective noise isolation at the expense of a deeper in-ear fit, though.
The Sennheiser MOMENTUM Sport have more features than the straightforward Sennheiser CX True Wireless. With the MOMENTUM Sport, you get active noise cancelling and biometric monitors integrated into the app. Their fit feels less invasive, and they're more water and dust-resistant. Their battery life is shorter, however. The CX True Wireless use the same app and can access similar EQ and control features. Their battery life is longer, but they lack noise cancelling and have a chunkier shape, and although they share the same water-resistant IP rating for the buds, their case is notably more basic.
The Jaybird Vista 2 Truly Wireless and the Sennheiser MOMENTUM Sport are exercise-oriented earbuds. The Jaybird buds boast an impressive IP68 rating for dust and water resistance and IP54 for the case to handle the grimiest trail. They're stable-fitting, but the ear tips and stabilizers are one-piece, which makes it harder to get a custom fit. Meanwhile, the Sennheiser's ANC is better. The buds have a lesser IP55 rating for the buds and IPX4 for their silicone case, which is still good but not as good. Their app is more comprehensive with sound and connection controls, and additional heart rate and body temperature readings.
The Sennheiser MOMENTUM Sport represent a flagship's evolution of the Sennheiser CX Plus True Wireless. While both share water resistance, noise cancelling, EQ, and ear stabilizers, the MOMENTUM Sport are more refined in execution with an upgraded IP55 rating for the buds. Their case is water-resistant, while the overall ANC is more effective, too. Their refined shape and updated ear stabilizer design are more stable and comfortable, too. On the other hand, the CX Plus offer good value with a more consistent sound, a capable app, and a greater continuous battery life.
