Sennheiser Momentum Sport Review: Polar-powered running headphones tested by 3 runners

The Sennheiser Momentum Sport are truly wireless sports earbuds built in collaboration with Polar that are designed to deliver that signature, high-grade Sennheiser sound when you’re hitting the gym or going for a run.
The Sport comes packed with audio smarts like ANC, dedicated modes for listening to podcasts and boosting bass with scope to make sure these buds best suit your preferred running sounds.
They also host some additional smarts to help give them added appeal with built-in heart rate and body temperature sensors also included that work with Polar’s Flow app, smartwatches like the Apple Watch and Garmins (heart rate only) as well as Polar's latest watches.
Testers Mike, Nick and Kieran have been marathon training and racing with the Momentum Sport to find out if these pretty pricey truly wireless earbuds deliver where it matters.

Thanks for the review! A few follow up notes:
Glad you used the touch sensitivity controls! Indeed, some runners are smooth and others stomp a bit more and this allows you to customize the experience to your running style.
We noticed you put the earfins ON TOP of the "blank" bands (see 11:07 into the video), which should have been removed when applying the earfins. This is incorrect and will add unneeded thickness, create a looser fit (they bounce around more, and may create the phantom tap you experienced), and HR accuracy. When used as directed you'll get much, much better results
We've posted a video on our channel on how these can be removed, it's easy and takes just a few seconds to do. We hope you get to check it out.

Hey thanks for the comment, the blank bands are on the headphones in the vid but this was just a mistake during filming when I was swapping them in and out. When running I just had the earfins, and experienced the problems mentioned in the video with HR accuracy.

Now do proper Garmin support, Sennheiser!

Any sounds from foot strike in the earbuds?

[@sennheiser]

These have a new acoustic relief channel built in, so footsteps are nearly silenced

[@bobbyblade1423]

can the hr sensor be turned off?

[@sennheiser]

It is always on, but only the app you choose can track/log, if the app is capable
