Using Polar products with Sennheiser MOMENTUM Sport

Sennheiser MOMENTUM Sport earbuds measure in-ear heart rate and body temperature during training sessions that can be analyzed and tracked with Polar products. The earbuds are completely compatible with Polar Flow ecosystem and can be managed in your Flow account just like any other Polar devices.

Body temperature tracking during training can be useful for both amateurs and pros alike. For example, how the body responds to extreme conditions, the importance of refueling and understanding the effect of body temperature on performance in the hardest sessions.


Sennheiser MOMENTUM Sports earbuds are fully compatible with:

  • Polar Flow app
  • Polar Vantage V3 with firmware v. 2.0 onwards
  • Polar Grit X2 Pro with firmware v. 2.0 onwards


After pairing, the earbuds will be registered to your Polar account just like Polar devices are. They can be found from your Devices list in Polar Flow app and Products list in Polar Flow web service.

  1. Insert the earbuds into your ears to turn them on.
  2. Go to Start > Training > Training settings.
  3. Find your earbuds from the list and tap Pair.
  1. Insert the earbuds into your ears to turn them on.
  2. On your watch, go to Settings > General Settings > Pair and sync > Pair sensor or other device and Pair MOMENTUM Sport xxxxx is displayed. Press OK to start pairing.
  3. Pairing done is displayed.

Use in training

MOMENTUM Sport earbuds can be used individually, but only the left earbud has the sensors for tracking heart rate and body temperature.

  1. Insert the earbuds into your ears to turn them on.

  2. Go to Start > Training and choose your sport.

  3. Wait for your body temperature and heart rate reading to appear on the top of the view.

  4. Tap Start to begin your session.

During training with the Flow app there is another training view for body temperature that can be accessed by swiping left.

After the training session, the body temperature statistics are included among others:

  1. Insert the earbuds into your ears to turn them on.

  2. On your watch, go to Start training, select your preferred sport and wait for the green circle around your heart rate reading to turn blue and a thermometer icon to appear. This indicates that the earbuds are connected and now measure your heart rate, instead of the heart rate sensor of your watch.

  3. Start your training session by pressing OK. The earbuds now record your heart rate and body temperature during the training session.

During training with the watch:

When you have connected the paired earbuds to your watch, there will be a new watch training view added for temperature. Access it by UP/DOWN like other training views.

It will show your

  • current body temperature
  • a time line curve of your body temperature during the training session
  • your average and maximum body temperature in your session so far

You can also add body temperature data fields to new training views of your watch in the Flow Sport profiles settings, like in this one:

After training with the watch

In the watch training summary the temperature statistics are included after others.
