Panoramica
The 30-Second Version
The MOMENTUM Sport nails build quality and ANC, but the sound is a letdown for a Sennheiser. The Polar fitness tracking is the real reason to buy. If you don't need heart rate data, skip these.
Pros & Cons
Pro
- Build quality is exceptional, top 3% of all earbuds we track 97th
- Adaptive ANC is genuinely impressive for workout buds 90th
- Polar heart rate and body temp tracking is a unique bonus 72nd
- IP55 rating means sweat and splashes won't kill them 67th
Contro
- Sound quality is disappointing for a Sennheiser product
- Mic performance is near the bottom of our database
- Connectivity scores are below average
- 6 hours of bud battery is mediocre for this price
Le prove
Performance
The build is the star here. These things are in the 97th percentile for construction, and it shows. IP55 sweat resistance, interchangeable fins and tips, and a secure fit that stays put during intense sessions. Adaptive ANC is also strong, sitting in the top 10% of earbuds we track. Battery life is solid at 24 hours total, though the 6 hours from the buds themselves is just okay. The quick charge is nice, 10 minutes gets you 45 minutes of playback. But the sound is a letdown. 20th percentile is rough for a brand like Sennheiser. The sport tuning leans heavy on bass, which works for the gym but falls apart for anything nuanced. The mic is also weak, landing in the bottom 15%.

vs Competition
Against the Sony ULT WEAR, the Sennheiser wins on build and ANC but loses badly on sound. The Sony is a more balanced all-rounder. The Technics EAH-A800 crushes the MOMENTUM Sport on audio quality, but it's not designed for workouts. The JBL Tune 670NC is cheaper and sounds better, but the build feels flimsy next to the Sennheiser. If fitness tracking matters, none of these competitors offer it. That's the Sennheiser's real differentiator.

Prezzo
Value & Pricing
Pricing is all over the place right now. We're seeing USD 130 to USD 145 across two listings, so shop around before you commit. At the low end, you're getting a fitness tracker and a pair of earbuds in one package, which is decent value if you actually use the Polar features. At the high end, it's a tougher sell. You can get better sound for less money, but you won't get the heart rate tracking.

Overview
The Sennheiser MOMENTUM Sport earbuds are a weird mix. Build quality is genuinely top-tier, and the Polar-powered fitness tracking is a neat trick. But the sound tuning lands near the bottom of our database, which is a strange look for a Sennheiser product. These are workout buds first, music buds second.
Common Questions
Q: Do these work with non-Polar fitness apps?
The Polar sensors sync with Polar's ecosystem and some third-party apps, but you'll get the best experience using Polar Flow or compatible platforms. Check app compatibility before buying if you're locked into a specific fitness app.
Q: How secure is the fit during running or HIIT workouts?
The interchangeable ear fins and tips provide a snug, stable fit that holds up well during intense movement. The IP55 rating also means sweat won't cause them to slip out.
Q: Is the sound quality good for non-workout listening?
Not really. The sport tuning emphasizes bass and energy, which works for the gym but sounds muddy and unrefined for critical listening. If you want balanced audio, these aren't the pick.
Who Should Skip This
Skip these if you care about sound quality first. The 20th percentile audio score is a dealbreaker for anyone who wants Sennheiser's signature clarity. Also skip if you take a lot of calls, the mic is genuinely bad. And if you don't need fitness tracking, you're paying extra for a feature you won't use.
Verdict
Buy these if you want a fitness tracker that also plays music. The Polar integration is the whole point, and it works well. If you just want good-sounding earbuds for the gym, look elsewhere. These are for people who care about heart rate zones more than soundstage.
